Coal crusher technological demand

Coal crusher technological demand: to achieve gangue monomer disintegrate from coal at maximum limits, increase the comparative surface of coal and coal quality, reduce ash content, higher heat productivity, remove the sulfur, phosphorus, etc harmful substance and reduce the air pollution produced by coal burning, coal must be crushing effectively.

In recent years, crusher task is being paid more and more attention with its main reason of coal crushing effect not only direct influence the whole coal washing and separating system, in whose process for adjusting, recording and measuring. And electromagnetic flow meter is mainly used for measuring flotation material separating, liquid and water flowing.

1.Strictly control product granularity

On economy factor, coal user has a higher requirement for finished product granularity with different granularity of different customers, which is changing continuously with market changing. Once it does not achieve the demanded granularity, the coal will become unsalable and unpaid by customer for unmatched granularity, which directly and heavily influence the coal industry and company economical profits. Simultaneously, different time and different particle sized product have different price, so company depends on coal crushing task for maximum profits.

On the technological factors, different washing and separating device have different range of handling granularity, which must be via crushing work for fitting the demand of washing and separating. Heavy medium swirler is the suitable washing and separing device of high efficient, strong adoptability, easy automation with widely application. But if the material granularity is ultra limit, the pump or pipe is easy to block without high efficient, to solve this problem, crushing work is needed to control the feeding material granularity.

2.Lower the powder smashing in coal crusher working process

The over crushing in crushing process not only cause the resource waste, which influence the company profits especially anthracite coal crushing, but also increase the water content after coal separating with clean coal lower productivity.

3.High handling capacity

Recently, 5 million ton/year even 10 million ton/year large and extra-large coal separating plant is increasing with simple coal separating flow require a classifying equipment of 1000-2000 t/h even 3000 t/h to fit for coal crusher working.

4.High reliability of device

Classifying equipment as washing and separating system key device usually adopts open circuit crushing method to achieve multifunction of graded crushing. Once this problem occurs, the whole coal crusher separating system will not run normally, so the high reliability is the basement of coal crusher separating system application successfully.

5.Low maintenance and simplicity of checking and repairing

For large sized modern coal separating plant of high output and efficient, the coal crusher device must meet the situation of high automation with low maintenance. Meanwhile, as high handling capacity coal crusher equipment, the whole machine is too weight to overhaul so the main part must have a reliable running with easy changing of wear-resistant parts in working site.
