What is Coal Crusher? What are the uses of coal crushers?

Coal crusher is also called coal mill, coal crusher is a kind of impact rotor crusher with a crushing ring, the crushing ring sling of the coal mill is on the suspension shaft that rotates with the rotor, the crushing ring makes a rotating impact movement with the rotor, and there is also a spin movement around the suspension shaft; The coal crusher crushing process is completed by two stages of work in the crushing ring. When the material enters the crushing chamber of the coal crusher, the crushing ring that rotates in the first section is impacted and crushed. In the second section, the primary crushed particles falling on the sieve plate are further crushed by the crushing ring and discharged through the sieve hole.

Small quantities of material that cannot be crushed are fed into the scrap room, which is then removed from the scrap room on a regular basis. The adjustment of the discharge particle size is realized by replacing the sieve plate of different specifications, and the gap between the rotor and the sieve plate can be adjusted by the adjustment mechanism as needed.

The coal crusher is not only suitable for crushing coal, but also for crushing minerals of various brittle materials such as salt, white bar, gypsum, alum, bricks, tiles, limestone, etc. Coal crusher is widely used in highway, railway, building materials, refractory, cement, ceramics, chemical and other industries for medium and fine crushing of materials. The compressive strength of the material of the machine does not exceed 100 megapascals, and the humidity is not more than 15%.

Coal gangue crusher belongs to high-efficiency fine crushing special equipment, also known as (coal gangue hammer crushing). The new coal gangue crusher is mainly suitable for the crushing of cinder, Shanghai slag, shale, coal gangue, construction waste and other materials of masonry and gravel, and solves the problem of using gangue and cinder as masonry additives and internal fuel; The problem of crushing high-moisture materials with gangue and shale to produce standard bricks and hollow bricks.

The jaw crusher is used to crush large pieces of ore, generally used for first-stage crushing, and the latter is generally used as a hammer crusher.

Coal crushing can be divided into extrusion coal crusher, impact coal crusher and shear coal crusher according to the main force of the crushed material. Extrusion coal crushers mainly include jaw crushers, gyratory crushers, cone crushers, roll crushers, etc. The working principle is:

The material is crushed by squeezing, splitting and bending between the fixed toothed plate and the movable toothed plate of the crusher. This kind of crusher mixes and crushes the materials in the crushing chamber, which is easy to form over-crushing, and is easy to form large flake products, which cannot guarantee the product particle size and large power consumption. It is mainly used for the crushing of hard materials, and is widely used in metal mines and gravel materials.

Impact coal crushers mainly include impact crushers, ring hammer crushers, etc. This kind of crusher is to hit the material with a high-speed moving hammer, after each blow, the material accelerates and flies to the impact plate, the repeated action of impact and counter-impact and the mutual crushing impact of the hit object in the crushing cavity, and a part of it is sheared under the action of the striking edge and the impact plate, so as to achieve the purpose of crushing the material. This crushing method has poor controllability, which will lead to the production of a large amount of pulverized coal, and the situation is worse when the coal with low hardness and high brittleness is crushed by this method, and there is a limit to the feed particle size, which is not suitable for the coarse and medium crushing operation of coal.

It is more suitable for coal crushing operations in power plants and coking plants. The double-toothed roller classifier of the British MMD company, the WMG roll crusher in Germany, and the double-toothed roller crusher produced by the German KRUPP company are all shear coal crushers. This type of crusher makes full use of the strength characteristics of rock, coal, coke, etc., and achieves the purpose of crushing through the shearing, stretching, bending, puncture, breaking, and splitting of materials.

This type of crusher has a good effect of energy saving and consumption reduction.

Jincheng coal gangue crusher is quite average, mainly worried about after-sales, if you want to buy a high-yield coal gangue crusher, or go to Xincheng Machinery to see.

Generally, I haven't used it, but I heard that Zhengzhou Yuantong Machinery's gangue crusher is good.

The best of Gongyi Hongji machinery. Now 85% of the country's brick factories are in use. Coal gangue crusher Hongji is the most professional.

Coal crusher is mainly suitable for coal-fired power plants, because the coal used in the boiler is usually raw coal that has not been graded, and the particle size of the raw coal does not meet the requirements of the boiler coal and needs to be crushed, so the coal mill should be set up in the coal conveying system of the coal-fired power plant to crush the coal into a certain particle size to meet the requirements of boiler combustion.

The PCH ring hammer crusher is most suitable for crushing all kinds of brittle materials, such as coal, coal mine, coke, slag, red sandstone, shale, loose limestone, etc. The compressive strength of the material does not exceed 100MPa, and the surface moisture is not more than 15%. The equipment can adjust the gap and change the discharge particle size according to the user's requirements to meet the different needs of different users.

There are many types of coal crushers, such as the common jaw crusher, the hammer crusher equipment is better, cost-effective, the equipment is cheap, and the wearing parts are few.

There are also many roller stone crushers or toothed roller crushers used for coal crushers.

Coal crushers generally use roller crushers, two-stage crushers, etc.

Generally, commonly used coal crushers include jaw crusher, hammer crusher, impact crusher, cone crusher, compound crusher, etc.

The emergence of coal crusher solves the problem of crushing and crushing because of the high moisture content of the material, and the biggest advantage of the coal crusher is that it can also produce normally in rainy days. Because the coal crusher does not have a screen bottom grate bottom. Unlike traditional crushers, once the moisture content of the material exceeds 8%, it will clog and even burn the motor.

In addition, if you invest in a coal crusher, you can save investment costs in terms of discharge particle size, why do you say so, because the particle size of the coal crusher is very uniform, which can be controlled below 2mm (mm), while the traditional crusher must add a sieve to screen out the ideal particle size.

Now with the promotion of urbanization construction process, crushing equipment abounds, the competition is quite fierce, some manufacturers even ignore the interests of peers to lower the equipment, to know that behind this pressure is the crushing equipment material, parts, technology, technology, after-sales guarantee and other problems of condensation more crusher quality problems, even more no after-sales service, no technical support,. Because of the characteristics of strong water holding capacity, large viscosity, fine particle size, etc., the working capacity of the general crusher can no longer take effect or the finished product is a big problem, so I personally recommend choosing professional slime crushing equipment.

Buying crushing equipment is not the only consideration, as the saying goes, a penny for a penny, it can be said that how much money can buy how much is worth of grinding equipment, crusher users pay more attention to the quality of crusher equipment, crusher after-sales service, crusher technical support, crusher efficiency, crusher service life, etc., if you want to rely on the manufacturer, sincerely recommend Zhengzhou Huake machine for you, the company's professionals accompany you throughout the process, and design the perfect plan for you.
