Concrete Grinding Mill

Posted on: February 12th, 2018 by

Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a robust stone-like material. Concrete is used to make pavements, pipe, architectural structures, foundations, motorways/roads, bridges/overpasses, parking structures, brick/block walls and footings for gates, fences and poles. 

Concrete is used more than any other man-made material in the world.As of 2006, about 7.5 cubic kilometres of concrete are made each yearmore than one cubic metre for every person on Earth.

The purpose of the Shenbang High Pressure Grinding Mill is to grind materials in the fields of building materials, mining, metallurgies and chemical industry. The materials should be non-flammable and non-explosive. Examples of the materials are: quartz, feldspar, barite, fluorite, dolomite, garnet, carborundum, bauxite, zircon, marble, calcite, iron ore, rock phosphate, coal, ceram, slag and so on(400 kinds of materials). The materials should have the hardness less than 9.3 in Mohs scale and humidity less than 6 percent. The granularity of the end products can be changed from 30 to 425 meshes.

The High-pressure Suspension Grinding Mill has the same working principle as Raymond Mill, but its grinding fitting is furnished with 1000 1500 kg pressure spring. When the machine works, the grinding roll, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure ratio is 1.2 times of that of Raymond mill given an identical condition, but its output may increase 20% to 30%When the grinding roller and grinding ring reach a certain degree of abrasion, please adjust the length of high-pressure spring to keep the constant grinding pressure between grinding roller and grinding ring, so as to ensure a stable output and fineness. 

Features Of The Three-ring High Pressure Grinding Mill:

1. High-efficiency and low consumption

With the same end-products fineness and motor power, its output is over 1 time of that of Jet Mill, Mix Mill, and Ball Mill.

2. Easy-damaged parts with longer working life

The grinding roll and ring are made of special materials. Generally, their work life is more than one year, but, which could come up to over 3 years, when it processes calcium carbonate and Calcite.

3. Security and Reliablity

Because there are no rolling bearing and bolts in the grinding chamber, we can not see the problems of bearings and sealings easily damaged and machine destroyed due to the bolts looseness.

4. Cleansing and Environment Protection

Adoption of Pulse dust collector and muffler reduces the industrial dust pollution and noise, which reaches the National Standard.

When the machine works, the grinding roll, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure ratio is 1.2 times of that of Raymond mill given an identical condition, but its output may increase 20% to 30%

Concrete Washout Systems

Posted on: February 3rd, 2018 by

Construction sites have long been identified as a major contribution to the pollution of urban runoff pollution prevention good practice not carried out regularly. Materials washed into the storm drain have a direct impact on local waterways and habitats in this environment.

The most common discharge into our storm drains from concrete construction of residues and contaminants from washing down equipment such as concrete trucks, pumps, mixers, chutes, hand tools and wheelbarrows.

In this regard, a high potential for pollution of urban runoff, U.S. Environmental Protection Agency (EPA) has intensified its efforts to keep storm water pollution prevention plans are compatible with the National Pollution Discharge Elimination System. All of these essential criteria are part of the U.S. Clean Water Act and mandates the use of best management practices (BMPs) on construction sites. Potential emissions of the storm drainage systems from concrete work has become a priority of federal and state EPA, water quality control officials, regional and local inspectors, as well as the strategic goal of advocacy and environmental groups. Illegal discharges into our waterways can bring a fine of $ 32,500 per day if the U.S. EPA is involved.

Polished Concrete Process

Posted on: January 25th, 2018 by

Polished concrete is strong, durable and low maintenance while having that earthy texture of stone with a polish equal to granite. Here is how it is done.

It is similar to traditional polished terrazzo which is very flat and poured as a special mix to make the finish more successful. Polished concrete floors can also look almost bumpy and have little or no aggregate showing. Flatness and polishing are not necessarily the same thing which is a good point to clear up before agreeing to your project.

It costs extra time and diamond wear to cut floors with a concrete grinder until they are flat. They can either be ground flat to fully expose the aggregate like terrazzo, or the aggregate can be partially exposed, or the concrete grinding can expose no more than the fine sands at the surface. It often takes skill and experience to control the process of polished concrete floors and the quality of the concreter’s original laying work is also a contributing factor in the quality of the finish. Where the aggregate is a feature special materials can be added to the wet concrete mix such as coloured pebbles, metals and glass to enhance the final appearance.

Most people are unaware that there are ten to fifteen steps for polished concrete floors which takes a long time to complete and can be quite expensive.

Typically it takes many grinding passes to finish a highly polished floor although there are other ways as explained later. The general rule is to double the diamond grit size under the concrete grinder for each pass so a contractor might start with very coarse, 16 or 32 grit size diamonds, then use 60 grit diamonds followed by 120, then start again with a 50 grit diamond resin pad instead of a metal segment. Using the resin pads the steps may be 100, then 200, 400, 800, 1500 and finally 3000 grit. That would be ten separate grinding passes which does not count the two other essential steps.

Two more essential steps:

1. Hardening the surface

Polished concrete floors usually have the surface hardened with a chemical before the second, third or fourth grinding pass. The chemical soaks into the floor to a few millimeters (up to half an inch) and causes a chemical reaction to take place that makes the floor harder and easier to polish to a high finish. These floors are very strong and durable without having a surface coating.

2. Filling holes

After the first concrete grinder pass removes the top layer of concrete paste it will expose millions of tiny air holes. If these are not filled before the hardening process then the final polished concrete floor will show these unsightly imperfections. The holes are usually filled with an acrylic tile adhesive type of product mixed with either the grinding dust or cement powder which is hand scraped across the floor using a trowel. The preferred way to fill the holes is to spray the acrylic adhesive ahead of the grinder so that the diamonds mix it into the holes with the grinding dust on the third or fourth pass at around 120 grit. This method is faster and the dust matches the colour of the floor to hide the holes better than when using cement powder.

Very flat or slightly bumpy polished?

Some floor grinder machines are designed to produce a very flat floor by cutting off the high spots while some others are designed to follow the contours of the floor more. If the surface is to be polished without necessarily exposing the aggregate then only the finer resin pads need to be used on a concrete grinder that allows for movement of the pads so they can follow the contours of the surface. This will result in a polished floor without showing the pattern and texture of the exposed aggregates within the concrete which is faster and less expensive. Hardening can still be an advantage to help the durability of the surface and to produce a final gloss.

Problems with exposed aggregate

Sometimes the finish of exposed aggregate can be uneven if the mix of concrete was poured unevenly or finished off poorly. Boot marks or kneeling board marks can appear suddenly because they have pushed the aggregate down further which might require grinding down another two or three millimeters (quarter of an inch) which will cost more than was quoted. Grinding this far may not be what the customer wanted either so it can be a risk.

Single head or multiple head machines

Original terrazzo grinding was done with single head floor grinders until the production of three-head planetary machines. Planetary means that each head turns one direction while the turntable that houses the heads turns independently in either the same direction or the opposite direction. Some grinders can vary the direction of both the turntable and the heads and some can vary the speed of each. There are also multiple head planetary machines with four or more heads.

The planetary heads can follow the contours better than single or twin head grinders and are faster to use with less effort due to eliminating the requirement to physically move the grinder from side to side or in a circular motion. Single head terrazzo grinders should be moved in a circular motion to avoid grinding lips or shoulders.


As with wood floors the edges must be finished separately to the main floor area because the large machines may bump and damage the walls if they are used too close. For the first grinding passes a nine inch angle grinder is used having a diamond wheel attached with a dust extraction shroud fitted to remove the dust. The sit-down-to-use edge grinders are more controllable than stand up grinders while kneel-to-use grinders have good control, but are exhausting.

After the first two or three cuts a different dust extraction shroud with a corner feature is used with a seven inch polisher or a five inch, multi speed grinder to polish with resin pads and get tight into the corners.

Simple polished concrete floors “look”

The number of processes for polishing concrete can be reduced by up to 60% and still achieve a similar appearance by grinding and then coating with a clear sealer. The first step is to grind with 30/40 grit diamonds to expose the aggregate, then fill all the small air holes as described above (in 10 to 15 steps….) before a second grind with 60/80 grit or 80/100 grit diamonds.

This will produce a smooth enough surface to coat with a sealer. Polyurethanes are very hard sealers with a high gloss and can be purchased as UV stable to stop yellowing (usually double the price of non UV stable urethanes), clear epoxy sealers are not as smooth and will chalk and deteriorate if exposed to sunlight and acrylic sealers have a much shorter lifespan due to their poor resistance to wear. Two coats are necessary to provide a high gloss level.

Different ways to achieve “polished concrete”

The first is to cut the floor with coarse diamonds until all the high spots have been removed to produce a flat floor and then use all of the 12 to 15 steps to eventually polish it or as it is sometimes called, hone it. This is the true polishing system.

A variation of the above is to cut perhaps half of the height of the higher peaks by starting with a medium coarse diamond grit and proceed through to polishing using a machine that can ride up and over small rises.

A third alternative way of producing a honed surface is to start with relatively fine diamonds and simply polish to top of the surface after hardening without removing much of the top cement paste. It is easier to do this when the floor has been laid flat and smooth.

Lastly, a “polished look” can be obtained by grinding with coarse diamonds and then fine diamonds before coating over with a clear sealer.

Only truly polished floors will retain their gloss with little maintenance because all coatings scratch with wear and lose their high shine. Special buffing pads on a standard floor polisher that contain very fine diamonds can be used to maintain cleanliness and the high gloss levels of true polished concrete. Janitors can be provided with these and keep the floors in great condition without special treatment.

Some hire companies provide the grinding equipment for do-it-yourself concrete polishing and have all the pads for the purpose. This may not be so economical though because the pads may be only half worn when you finish depending on the area involved.

Concrete Protector For Your Concrete Surfaces

Posted on: January 14th, 2018 by

During the past few decades, the protection of concrete floors has shifted to a fairly sophisticated process of protective coating or surfacing. The main aim is to provide clear weatherproof protection against deterioration caused by gasoline, oil, de-icing salt, grease, weathering and efflorescence (white, powdery, salt-like deposits visible on surface). Efflorescence occurs when moisture moves through surface. And, the moisture picks up minerals, carries them to the surface and leaves them behind in the form of tiny crystals on the surface as it evaporates.

Concrete Protectors: Why Use Them?

The main reason to use a concrete protector is to restore and beautify existing surface. Cleaning concrete periodically will provide protection to the surface from deterioration or contamination, and provide some benefits such as chemical resistance, physical performance, aesthetics, wear, and a myriad of other benefits. You can also consult your manufacturer for an expert advice and see samples of various finishes achieved by surface cleaners, polishers and protectors.

How much maintenance is required?

Mostly all surfaces, when coated with a concrete protector, are resistant to stains, dirt and grease. Still, they need occasional cleaning to look their best. Ask to have a cleaning and maintenance procedures and life-time performance expectations before committing to a surface care regimen. Concrete floors are susceptible to wear and abuse. They are also subject to abrasion and chemical attack. It’s for this reason that all concrete needs some sort of protection. Some recommend protecting surfaces annually, depending on the amount of traffic they receive and whether they are exposed to freeze-thaw conditions.

Be sure to check with the manufacturer for recommendations as to the appropriate cleaner to use for a particular application and to verify compatibility with the cleaner. Not all cleaners are suitable for exterior use. The flooring expert can guide the owner in application, long-term performance, thereby reducing the overall cost of floor-maintenance. To keep maintenance manageable, you will need to choose the right cleaner. For instance, for cleaning a walkway, you need a coating that repels grease and oil and prevents water penetration.

As flooring evolves to meet changing tastes and needs, so must the products and procedures used to enhance the beauty of surface. Although recent innovations such as concrete protectors have made floors easier to clean, they have also met both beauty and budget standards. A concrete protector, can give lackluster concrete a decorative makeover or restore it to like-new condition at a fraction of the cost.

Concrete Solutions With Australasian Concrete Specialists

Posted on: January 12th, 2018 by

Concrete is a word that has been derived from the Latin word “concretus,” which means compact. Concrete is a special mixture made with cement and other materials like aggregate and fly ash mixed with water and chemical bonding agents. For concreting to be done right, people usually go to the concrete specialists. They are the people who are well trained in concreting methods and materials. Australasian concrete specialists are experts in this field.

The Concrete And Its Specialists

Driveways, patios, pool front, garage pathway – all these are to be concreted just right to give the home a nice and fine look. Today concrete is not just boring and grey. It comes in different colors and patterns. They can be custom-colored and patterned to suit the needs of the clients. Spray paving is something new and unique to the concrete world. It is a technique where a pattern is sprayed on to the ordinary concrete, when it’s set, to give it a whole new appearance. Spray pave material can also be applied on to old concrete surface.

It’s actually polymer cement that is made in such a way that it can be directly applied on to the concrete. The resurfacing done with spray pave is durable and slip-proof, which is ideal for any surroundings. It also allows a person to have any kind of design sprayed on. Therefore, the options available with this method of concreting are almost unlimited. This method of concreting is a part of the decorative concrete arena. The other methods of decorating on concrete are stamped concrete, acid staining, and polishing. Stamped concrete is actually patterned concrete. It gives the concrete a completely different look. The concrete can be made to look like stone, bricks, or other material when it is stamped.

Whatever may be the method of concrete used, unless done by the experts, it can go terribly wrong and spoil the entire look of the area. This is where the concrete specialists come in. The specialists are experts in concrete and can give solutions to any concrete problem. The Australasian concrete specialists come to your homes and do the magic. They pave the path or concrete the driveway just the way the client requests and make sure there is no room for error. They are trained in all the new concreting materials and methods. They can advise the client as to what would suit best in the given area and circumstance. These specialists also can help to reseal concrete. Resealing is required to maintain the concrete. This can be done every two or three years. It is always better to call on the professionals to do the resealing.

Australasian concrete specialists are there to help people who want to give their homes a completely different look without too much cost. They convert a very ordinary driveway or entrance pathway into a beautiful place which would be the envy of the neighbors.

Things You Should Know About The Imprinted Concrete

Posted on: January 10th, 2018 by

There are different ways in which you can decorate the concrete in your house. For example, you can use different types of colors and dyes to bring in different types of shades on the concrete. However, if you want different interesting textures on the concrete, you can easily do this with the help of the rubber imprinting stamps. The Imprinted Concrete can have very interesting looks and can be used widely in different sections of the building.

In this process, the rubber imprinting stamps are pressed on the wet slabs and concrete. The impression is done to resemble the texture of natural stones or brick. Generally, these stamps are made from the molds that are made from the authentic wood or stone. Also, there is some release agents applied to the stamps so that they don’t get attached to the surface of the concrete. These release agents are available in both liquid and powder forms.

However, there are different types of imprinted concretes available in the market. They vary widely in terms of the textures. However, if you are looking for something creative for your concrete slabs, the overlays are one of the better options that you have. In fact, there are different types of overlays available including the stamped overlays.

In this process, the rubber imprinting stamps are impressed on the thin and pre mixed concrete overlay. Actually, the concrete overlays were first used during 1960s. This was the time when some leading chemical engineers of the time started to experiment with the acrylic resins and its effect on sand and cement mixes.

They found a thin topping material that can be easily attached to the concrete surface and thus, a resurfaced coating can be provided for the worn out concretes. Soon, this process became very popular. However, one major drawback of this process was that these overlays can’t perform for a long time. But, the acrylic resins provided good protection from the UV rays though they lacked in water resistance.

However, the polymer cement overlays seem to be an effective solution to this problem. Basically, these overlays consist of polymer resins, Portland cement and different aggregates. This combination enhances the capacity of the overlay to a great extent and at the same time, it lengthens the longevity and maximizes the versatility of the overlay. What’s more, these overlays can be applied both thinly and thickly without any fear of product failure. They are also very resistant to the petrochemicals, salt, harsh weather, and the UV.

The polymer cement overlays were actually used for the restoration of worn out concretes by using a thin coat on them. However, in 1980s, these overlays were introduced in the commercial flooring as well as in the architectural concrete. Soon, it becomes quite a regular affair as they are economical and durable for a long time. Also, the maintenance is relatively more convenient and comfortable as well.

Permeable Concrete Pavers – Smart Solution For Temporary Parking Lots

Posted on: January 3rd, 2018 by

Temporary parking lots have become popular in recent times mostly due to the space constraint that we are faced with. Moreover there is much less free time in hand to search for a favorable location and go in for a step by step parking lot construction. Today, with soaring demands for overnight setups, for example in case of big events, temporary parking lots are finding more audience than ever before. But along with construction there comes the question of maintaining the place and keeping it clean. Recently a Sydney based company has come up with a new concrete cleaning technology which they call “high pressure cleaning”. It essentially consists of shooting water out of a hose at a high force of 1000-3000 psi (Ibs/sq inch). This high pressure enables pressure-cleaning of tough grease-stained surface like parking lots. Using pressure cleaning technology may prove effective for temporary parking lots as well which are made up of permeable concrete pavers. This will certainly reduce the time spent in cleaning the parking spaces as well.

If you are wondering why permeable concrete pavers are increasingly being used in temporary parking lots, it’s nothing to be surprised at all. For almost every social event there is need for adequate space to park a lot of cars temporarily. In such situations, short term parking lots covered with permeable concrete pavers come across as a cost-effective and convenient solution. Take a look at the various advantages of using permeable concrete pavers over common asphalt paving.

An Innovative Time Saving Concept:

The need for a temporary parking space that’s dry, safe, clean, and secure all at the same time helped to popularize permeable concrete pavers to a large extent. To top it, this innovative technology saves time and is environment-friendly.

Easy On the Pocket:

Traditional asphalt is more expensive than permeable concrete pavers. Besides it’s not an easy task to remove asphalt cover from surfaces, whereas permeable pavers made of concrete can be easily removed as well as easily reinstalled. This further helps the customer in recovering about half of the initial installation cost.

Eco-Friendly Alternative:

From an environmental point of view, permeable concrete pavers are favorable over asphalts and other impervious materials. Due to its permeability, these special types of concrete paving allow water to percolate through the surface into the sub-soil. Hence it resists soil erosion as well as helps to restore the ground water level. Researchers have confirmed that permeable concrete pavers are especially effective in places previously affected with soil and water pollution.

Tempark offers an all-round solution for temporary parking lots. Hence, when it comes to installing permeable concrete pavers you shouldn’t look for any other!

Personalization – The New Statement for Polished Concrete

Posted on: December 30th, 2017 by

For demanding clients, customization is an old word. Personalization, however, is the buzzword for the moment. More than just a place where people move on, polished concrete delivers a unique style statement. Thanks to the many decorative possibilities available today, the options for making your concrete turn into an elegant jewel are endless. Stamped patterns, colored concrete, concrete engraving, intricately sawed or grooved patterns and concrete acid staining are just a few of the ways you can enhance the beauty of your polished concrete flooring.

Application Areas

The benefits of diamond concrete polishing are numerous as it provides an extremely smooth surface, and any possible look at a fraction of the cost. Some exterior applications of diamond concrete flooring are engraved concrete patio, driveways, and parking lots, entries, walkways, pool decks and patios. While, some interior applications are engraved concrete entry, fast food establishments, restaurants, shopping malls and residential entryway.

How to Maintain Your Polished Concrete?

Treat It With Care

Although concrete is one of the most durable paving materials, avoid the use of metal blades that might scrape or scratch the surface.

Remove Oil, Gasoline, and Spills Immediately

While a sealer will help to protect concrete from stain absorption, it is still a good idea to remove oil, gasoline, grease and other spills as soon as possible.

Avoid Using Deicers On Surface

In the winter using deicing chemicals on your concrete driveway can cause scaling and spalling. Products containing deicers are thus harmful because they will attack the concrete chemically.

Clean Your Concrete Regularly

Cleaning your concrete is the best measures you can take to keep it looking at its best. How often you clean will depend on the weather conditions the concrete is exposed to and the amount of vehicle traffic it receives. Ask your contractor for recommendations. Always apply and clean your floor according to the contractor’s recommendations.

How to Find a Diamond Concrete Polishing Contractor?

Get the names of the contractors who carried the polishing projects that appeal to you most. Be sure to ask about their experience and the quality of the workmanship. Once you come up with a list of polished concrete contractors, ask for references and get a list of concrete flooring projects in your area that you can personally check out. Also ask how long the contractor has been in the business, whether they have any professional certifications, and if they offer a warranty for their work.

The versatility and high light reflectivity of polished concrete are major benefits, especially for office buildings, hotels, restaurants, showroom floors, airports, shopping malls and other commercial facilities that are keen to project a bright, clean and professional image to their clients.

Guide To Building A Concrete Slab

Posted on: December 26th, 2017 by

More commonly used for making walkways, patios or foundation for a structure, concrete slabs are getting popular as an additional option for improving the beauty and durability of an area. With a good walkway, there will be no need to muddle through rain puddles or muddy areas. It is absolutely reasonable to design a slab that has a quality of not only being functional but also blends in the garden or porch. This simple article explains the basic steps to build a concrete slab and it is not only easy but needs a minimum cost to complete.

There are few things to consider like level and smoothness which is very important if it is the foundation for the house. The plan has to be well made and it must be ensured that everything is prepared for carrying out this project. The last thing required is to patch or trench the foundation. It is a boring and tiresome work when the needs of plumbing and electric means are not considered.

Before pouring cement on an area to set the foundation, the size and the location has to be determined that is to be occupied by the slab. For easy referencing, the stakes should be positioned for marking the boundaries. Any necessary adjustments can be made to the design as it is planned. Next, the area of vegetation has to be cleared. Few inches of the topsoil can also be removed and the dirt should be leveled to form a shallow hole. Some local authorities can also require to a vapor barrier below the dirt. This has to be confirmed with the local building authority. For setting the base for the slab, gravel should be spread over the hole. Steel mesh should also be laid. They are to be wired at the intersections with the help of pliers. This will strengthen the foundation where pressure is the highest.

Next, a form has to be used to keep the concrete well in position during finishing process. The string line will ensure that the form is square. For giving additional stability, they have to be nailed together. The slab level is supposed to be balanced in every direction. The sides of the form may be adjusted for accurately balancing the design. A cement mixer will work best for evenly mixing the materials that are required for the foundation. When cement is being poured, the shovel has to be made ready for evenly layering the cement. A ‘push and pull’ sawing motion can be used to layer the cement. It should be given time to dry. Anything heavy should be kept away from the area and it may take almost five days for a driveway.

The discussed steps and tips are the basics for building a concrete slab. A careful and successful builder will consider all the matters for ensuring the safety of the building’s occupants. In this matter, extra measures have to be taken for ensuring the stability of the concrete slab.
