ZENT ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. Ball mill is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine.

Ball millis widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. It has two ways of grinding: dry process and wet process.

The main bearing of the ball mill with the shell diameter 900-2100mm is spherical liner bearing; for the shell diameter 2700mm, the main bearing is completely closed self-aligning 120bearing with strong alloy of high lead and low tin with low hardness, underneath laid with cooling copper piping full of water The bearing is of static pressure structure with high and low pressure united oil lubricating system.

Ball mill can be used widely in coal ball milling plant, silica grinding plant, quartz grinding plant, manganese grinding plant, limestone powder plant, limestone grinding plant, iron ore grinding station, coal power plant, coal processing plant, bauxite grinder plants, cement grinding plant etc.

1. The ball mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on. 2. The hollow axis adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears. 3. The barrel body is inlaid with wearable plates. 4. The machine runs steadily and efficiently.

This Ball Mill, a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding. In the end, the powder is discharges by output material board.

The cement roller press is a kind of cement equipment for brittle materials, apply for cement clinker, and cement raw material, gypsum, coal, quartz sand, iron ore, blast furnace slag, and other materials.

The cement roller press is generally applied to the cement grinding plant, according to the real working process, cement roller press works with cement ball mill or vertical cement mill, which helps cement grinding plant to works well.

As new-type and energy-efficient cement grinding machine, cement roller press has advantages of energy-saving, high efficiency, less steel consumption and less noise. Both apply for new cement plant building and old cement plant revamping. According to the data, roller press helps ball mill system to increase the output by 30-50%. The 0.08mm fine material in the extruded material cake accounts for 20-35%, and smaller than 2mm accounts for 65-85%.

install the roller press in the cement grinding plant, the high pressure load is transmitted to the layer of the grinded material through the diameter of the double roller, most of the energy is used for the mutual extrusion between the materials. The sound energy and thermal energy generated by the friction of the material are transformed into the deformation energy of the material, which causes deformation, tearing and pulverization and fully utilize the potential of the cement grinding equipment, increase the output by 50-100%, and reduce the total energy consumption by 20%-30%. Promote the production efficiency of the entire system.

The material after grinding is greatly reduced in both particle size and the Bond function index, thereby greatly improving the grinding condition of grinding machine, and the power consumption of the entire cement grinding system is significantly reduced. It can save25-50% energy compared to traditional grinding methods, and the annual electricity saving are considerable.

Compared with the tube mill, the roller press is simple in structure, small in size, light in weight, and takes up less space in the workshop. It can save civil construction investment and also facilitate the original investment. In addition, the operation and maintenance of the roller press is very simple.

The material is squeezed and smashed continuously in the roller cover, and the harmful dust is not easy to spread. At the same time, the noise of the roller press is much smaller than that of the tube mill because of no impact.

The traditional tube mill is limited by processing, transportation, heat treatment and other conditions, and the large-scale tube mill is greatly restricted. The roller press grinding system solves such problems well.

The roller press works according to the principle of high-pressure layer pulverization, and adopts the work mode of single-grain pulverization. The brittle material is subjected to high pressure extrusion (the pressure of the machine in the pressure zone is about 150 MPa), the particle size of the material is rapidly reduced, the fine powder content of less than 0.08 mm reaches 20-30%, and the material of less than 2 mm reaches 70% or more, and a large number of cracks are present in all extruded materials, so that the energy required for the material to be ground in the next process is greatly reduced.

The main body of the roller press is two rollers that rotate in opposite directions, one is a fixed roller and the other is a movable roller. The brittle material is fed into the weighing chamber with the load cell by the conveying device, and then passes through the feeding device of the roller press into two rolls of the same size and opposite to each other, and the material is pulled into the nip by one side of the roller. The material is pressed into a dense material cake with high pressure, and finally falls from the nip, and is discharged from the hopper by the conveying device. The cake is further dispersed or ground by the next process.

Both the cementball mill and the cement roller press have their own advantages and disadvantages, but in actual production, the cement roller press has the advantages that the ball mill does not have, mainly reflected in the following points.

Note: Due to the large force of the roller of the roller press, the roller press has some problems, such as the material and the wear of the roller surface, the bearing is easily damaged, and the gear of the reducer is prematurely broken. In addition, the process operation process is strict. For example, the feed material column is required to be dense and full, and a certain feed pressure is maintained. The feed amount control should be appropriate, and the grinding process system configuration should be appropriate, otherwise its superiority cannot be exerted.

comparative study on improving the ball mill process parameters influencing on the synthesis of ultrafine silica sand: a taguchi coupled optimization technique | springerlink

Taguchi-based experimental design technique has been a major research area for making systematic approaches to understand the complex process of ball mill process parameters influencing on the synthesis of ultrafine silica sand monolayer degradation. To determine an optimal setting, Taguchi coupled optimization technique has been applied with a novel approach as there is no previous work focusing on the synthesis of ultrafine silica sand taking in account the ball milling process parameters and Taguchi coupled optimization techniques. The high-grade silica was milled in planetary ball mill and the selected samples were passed through washing, crushing, dehydrating, meshing and drying operations. The samples were analyzed using Malvern Instruments for particle size distribution. The experiments were conducted as per Taguchis L9 orthogonal array. Process parameters were analyzed using the signal-to-noise ratio based on the-smaller-the-better approach. To minimize the effect of uncontrollable variables, The ANOVA results determined the significance of the influential controllable variables so that the variability in the response is small. Optimization results confirmed that the balls to powder weight ratio were the most influential process parameter. The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum speed of the ball mill is 105rpm. Using SEM characterization, the improved particles of silica sand presented a spherical shape with a cluster. Using TEM of different structures of the ultrafine silica sand containing asymmetrical characteristics of particles confirmed the solid form of the ultrafine silica sand.

what is a sand mill?

what is a sand mill?

A sand mill is a piece of industrial equipment designed to grind a given material into very small particles of roughly equal size. Sand mills are used for processing a wide variety of products, and can also be used as mixers and dispersants, creating a uniform mixture of several components during the grinding process. A number of companies produce sand mills for various applications, including different designs and sizes to meet the needs of various applications.

In a sand mill, a central bar agitates the sand, causing it to have a grinding action. Many sand mills produce very small particles on the first pass, with the particles passing through a mesh screen. Others have recapture systems, allowing people to pass the mixture through the sand mill again to make it finer and more even. The design works by agitating the sand, rather than creating pressure, ensuring that the grinding medium does not break apart in the device when it is used properly.

As the name implies, sands can be used as grinding media, but other materials may be used as well. The choice of medium depends on the material being ground. Some companies maintain several mills dedicated for specific uses, while others may change media as needed in a single sand mill. Sand mills are used in cosmetics manufacturing, the production of paints and pigments, and similar activities.

In the case of mixtures, sand mills can be used to run a mixture of components through for processing into a uniform paste or powder. This is widely applied in the production of paints, where pigments need to be ground with stabilizers and other components before being blended with a base. As the ingredients pass through the sand mill, they become thoroughly mixed. The very fine grind offered by this device allows for highly stable mixes without patches and chunks of various materials.

Companies with need for a sand mill may be able to rent or lease equipment for their needs, offering an opportunity to test different kinds of equipment before making a decision to purchase. It is also sometimes possible to buy used and refurbished equipment from a manufacturer or third party. Brand new sand mills can be very expensive. Grinding media are available from sand mill manufacturers, as well as other suppliers. The operator must select the best medium for a given application, weighing a number of considerations, including concerns about contamination and discoloration.

I used to work in a sand mill and let me tell you, its like spending all day every day on a beach with a high wind. There is sand blowing everywhere all the time. It gets in your hair, your shoes, its coarsens up your skin and clogs up your nose. Every day I would go how and spend a good 20 minutes getting all the sand off my body. The pay was good and the work could be interesting but it gets round feeling like a human sandbox day after day after day.

When you start to look around there is sand everywhere. It is there as both sand and as concrete. When you thunk about it like this you start to realize how much sand it must take to support the world. It makes me wonder how much sand is produced every year. It must be hundreds of millions of tons. That is a lot of output but I have never once thought of where all that stuff comes from. Sand factories. Who would have guessed?
