Coal Washing Crushing Plant

Coal Washing Crushing Plant

Coal is a byproduct of coal washing process generated, which still contains certain low ash content, the direct sorting difficult to meet the quality requirements of sorted coal products, but if abandoned, will undoubtedly result in a waste of resources. Thus, coal re-election technology has become a hot research topic. Coal for re-election programs, according to the coal quality coal to choose, in general, the following two coal more common way of re-election. Due to the need of the market, users of the products of coal particle size requirements are very strict, different users have different size requirements, and such requirements as the market is constantly changing, so that the coal will once mainly the result of poor sales or granularity overrun and refuse to pay, directly affect the economic benefit of coal enterprises. At the same time, at different times, coal washing crushing plant different size specifications of the product prices of different companies in order to obtain maximum profit, it must rely on effective crushing operations. Deep processing of coal, clean coal washing and processing needs of coal in the process, in order to maximize the monomer solution with waste rock from coal, an increase of the specific surface area of raw materials, improve the quality of coal (ash content reduced to improve heat) to remove coal sulfur, phosphorus and other harmful substances, reduce coal pollution in the atmosphere caused by the combustion of coal must be effective crushing operations.

Coal washing crushing plant requirements, different devices have different washing process particle size range, the job must be broken in order to meet the requirements of washing equipment. For example: heavy medium cyclone is very high separation efficiency of washing equipment, and adaptable, easy to automate production, is widely used. However, if the particle size of the overrun washing products, can easily result in closure work phenomenon, it can not play an effective role in order to solve this problem it is necessary to strictly ensure the feed size by crushing. Reduce the crushing process is too crushing, crushing process over crushed, not only a waste of resources, the impact of the economic benefits of coal enterprises, but also after the election will increase pf water, slime water system pressure increases, the actual yield of coal re-election reduce. With the improvement of the pulverized coal and an increase in treatment costs of environmental protection requirements will minimize the amount of pulverized coal crushing operations will become the key.

Improve productivity crushing, crushing reduce the power consumption of great significance, then how to choose coal washing crushing plant? At present, in the form of coal washing crushing plant is very large, its main force crushed material can be divided into extrusion type, impact type, shear crusher, crusher mainly includes extruding jaw crusher, gyratory crusher , cone crusher, glossy or groove tooth roll crusher. Its working principle is: the material between the crushing machine fixed gear tooth plate and the movable plate being squeezed split and bending role to be broken. This kind of crusher crushing cavity material mixed broken, easy to form over the ground, and easily form a large sheet product, we can not guarantee product size, power consumption. Mainly used for crushing hard materials, widely used in metal mining and aggregates areas. Impact crusher mainly includes crusher, hammer crusher and so on. The crusher is a kind of high-speed movement of the hammer blow material after each blow, the material accelerated toward the impact plate, impact, reverse impact, repeatedly subjected to the same effect, while being crushed against each other was under attack in the crushing cavity , and part is cut in combating edge effects and impact plate. This fragmentation method controllability is poor, it will eventually lead to a large amount of pulverized coal, for high hardness and high brittleness of coal in this way when broken even worse, but also for the feed size is limited, not suitable for coal coarse, medium crushing operations. More suitable for crushing operations.
