Recently, coal crushing processing have been paid more and more attention ,In order to maximize the dissociation of waste rock and coal, to increase the surface area of raw materials, improve the quality of coal to reduce ash content, increase the heat, remove the sulfur in coal, phosphorus and other harmful substances, reduce the burning of coal in air pollution, must be effective crushing of coal.
1. Coal crushing processing Developing
On the economy should control the product granularity tightly especially those coal choosing customer for different demands. What’s more, this demand is changing with the market. Once the coal cannot reach the customer’s demand, the coal will become unsalable or returned back for no paying the unmatched granularity, which directly influence the enterprise effectiveness. Simultaneously, different period, particle size have different price, so enterprise have to adopt efficient crushing process to acquire more profit. On the technology, different selecting and washing equipment has different handling granularity scope, which all of these must approve the crushing process. Heavy medium swirl cyclone is the high efficiency separating and washing equipment with high adoptability and automatical used in many fields.
Over-crushing process not only damage the waste of resources, but also makes the coal powder have more water content, which cause low production of practical output. With the higher requirement of environment protection and higher increasing of coal processing fee, the key point is lowering the powder coal at lowest limitation.
2. Coal crushing processing Factory
Output of 5 million ton/year even more than 10 million ton/year coal separating plant increase rapidly, and the simplification of coal separating makes a demand of 1000-2000t/h even more than 3000t/h output grading & crushing equipment.
High reliability of grading, separating & crushing equipment is compared as the key equipment for open-circuit crushing system, which can realize double function. But once this equipment occur problem, the whole separating and washing system can not run normally.
3. Coal crushing processing
Low maintain and repair is suitable for large high output and efficient modern coal separating plant with high automatic. Meanwhile, as the high handling crushing equipment with heavy weight, it’s difficult to repair on the working site, so the wear-resistance part should be demanded for easy replacing on working site.
