Advantages and Working Principle of Coal Mill

It is known to all that Coal mill is an important auxiliary equipment for coal-powder furnace, and it has three methods to crush the coal lump and grind them into powder,like crushing, impacting and grinding. Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. Compared with the ordinary ball mill, it has advantages of higher capacity, more convenient operation, safer usage, and more reliable performance.

The raw coal enters the mill via an airtight feed screw and is discharged onto the centre of the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track where the coal is ground between the table and the three rollers. The coal then continues over the dam ring and is entrained in the hot drying air that enters the mill house through the nozzle ring. The air lifts the coarser particles back onto the grinding table and sweeps the finer particles up to the separator that lets the final product proceed to the mill outlet while returning the coarse fraction to the table for further grinding. Having left the mill at the top, the final product continues with the air to a cyclone or a bag filter where it is collected.

Of course, maybe my summary is not comprehensive. And we also have other mining machines, such as jaw crusher, ball mill sand maker and so on. If you have other supplement, you can comment about my article. We learn from each other, and make progress together. Thank you very much for reading my article. I hope you like it.

Air-swept Coal Mill Plays a Vital Role in Power Plant

Air-swept Coal Mill is an important auxiliary equipment of pulverized coal furnace. The grinding process of the coal is the process that the coal is crushed and its surface area increases gradually. To add the new surface area, it is necessary to overcome the binding force between the solid molecules, which requires the consumption of energy. Coal is grinded into the coal powder in the coal grinding mill mainly through three ways: crushing, shredding and trituration. Among these three ways, the way of crushing needs lowest energy consumption, while the way of trituration requires the most energy. The two ways mentioned above are generally used in the various kinds of coal grinding mills . According to the rotation speed of the parts in the coal grinding process, the coal grinding mill can be divided into low-speed coal mill , medium-speed coal mill and high-speed coal mill

Concrete is actually a kind of creating materials essential to interpersonal improvement. Recently, the actual concrete business has been around a continuing economic downturn and also the concrete manufacturing businesses possess slim earnings. Is actually which which means the marketplace doesn’t have powerful needs with regard to concrete? FOTE Machinery doesn’t believe therefore. Right now the actual urbanization building in a variety of locations is extremely warm, the reason the marketplace needs aren’t powerful? The essential answer is actually how the businesses ought to slow up the concrete production price to improve the actual income.

Utilizing air-swept fossil fuel generator ought to very first resolve the issue from the fineness from the fossil fuel powders. The actual fineness from the fossil fuel powders includes a excellent effect on the actual coming heat and also the combustion period. Growing the actual fineness from the fossil fuel powders may boost the shallow part of the strong cola within the fossil fuel powders as well as help to make it’s get in touch with region using the atmosphere improve, that is favorable in order to enhancing the actual combustion pace from the fossil fuel powders.

Two Main Problems often Appear When using Cooling machine

Cooling machine is regularly used in compound fertilizer production lines, to cool fertilizers with a certain temperature and granularity. If used in combination with a dryer, cooling machine can largely increase cooling speed, reduce labor intensity, and improve finished-product quality. Meanwhile, it can further reduce materials’ water content. Additionally, cooling machines are also applicable for cooling many other powder materials and particles.

The clinkers are lifted for many times in the lifting area, and evenly thrown about, and the cooling air will have strong heat exchange with the hot clinkers. Especially in the low-temperature area, through improving the structure and arranges patterns of the lifting boards and adjusting the inclination and rotary speed of the cylinder, the contact time of the clinkers and cooling air can be increased and the moving speed of the clinkers can be controlled, so that the heat inside the clinkers will have sufficient time to transmit to the surface, thus sufficiently recycling the heat of the clinkers with low temperature. This type of countercurrent heat exchange working principle is the ideal method for heat recovery of clinkers as the heat recovery efficiency is very high, but there are still problems lifted below.

1. The slow cooling of the clinkers in the high temperature area leads long length of the cylinder. Due to reason of texture, the temperature for long time use of the lifting board inside the cylinder should be about 900℃, and the temperature of the clinkers discharged from the kiln is generally 250℃~1400℃, which requires to set up a bricklaying zone without lifting board at the feeding mouth end of the cooling machine. This bricklaying zone not only increases the heat loss of the cylinder surface, but makes the clinkers cannot get quenching, thus influencing the quality of the clinkers.

2. There are many problems in the feeding chute of the hot end of the cylinder. As for modern dry process rotary kiln, especially the kiln using multi-channel coal-injection ducts, the temperature of the clinkers discharged from the kiln can be as high as 1350℃, which often crust at the chute end. For this reason, at the chute end there are usually installed many air cannon or timely deals with the crust with high pressure, which will damage the refractory materials.

Air-swept Coal Mill Plays a Crucial Role in Building Materials

It is known that coal is also called“black gold” which reflected its importance to human life. In fact, most of China’s power supply depends on thermal power. Hydro-electric power requires favorable location, and nuclear power is not safe enough, so only thermal power is the perfect and mature power generation by far. As coal-producing province, coal production in Shanxi has had a larger impact to the country’s electricity supply, and FOTE air-swept coal mill and coal crusher can also benefit from it.

Adopting air swept coal mill wind for grinding powder, and reducing the pulverized coal fineness, plays a crucial role in the cement rotary kiln production line, is proportional to the burnout time of the pulverized coal and grain diameter of quadratic, pulverized coal combustion. The smaller the pulverized coal fineness is, the larger the pulverized coal specific surface area is, the greater the pulverized coal with oxygen in the air is, the greater the contact area can reduce the ignition temperature, combustion is easier.

Air-swept coal mill produced by FOTE Machinery can be widely used in concrete building materials, thermal power generation, metallurgy, chemical industry and so on. Air-swept coal mill has reasonable structure and high grinding efficiency, so it is ideal equipment for pulverized coal preparation. FOTE air-swept coal mill is edge driving mill driven by electric motor through reducer and gears. The grinding machine used wind-swept-type structure with a drying storehouse, so it has greater adaptability on coal with certain moisture. The grinding house of FOTE air-swept coal mill is followed by the ladder liner, double ladders, ruffle liner and other combined layout, improving grinding ability of the grinding machine.

Using FOTE air-swept coal mill, low quality coal, coal with high ash content, coal with poor net calorific values or low volatile bituminous coal and anthracite coal can be used in cement production line. With excellent FOTE air-swept coal mill, even “defective raw materials” can become wealth.
