Different types of crushing circuit involves various crushing machines, the primary crushing process circuit usually includes only a crusher and auxiliary equipment of vibrating feeder and conveyor. Except the prime equipment, secondary and tertiary crushing circuit also have impact crusher or cone crusher and vibrating screen or storage bins.
SBM provides coal crushing production line capacity range from 800tph-1200tph. Of these crushing machinery, the coal crushing plant capacity 200tph is the best choice for medium scale coal mining project. We also developed mobile coal crushing equipment for sale, which can be equipped with jaw crusher, impact crusher, cone crusher and screening machine for different applications. There are also used coal crushing machine with low price for choice.
Coal Preparation Production Line
coal preparation production line begins with crushing and screening of freshly mined coal, which normally results in removal of some of the non-coal material. Some coal, especially coal from thick-bedded surface mines, is merely crushed and screened before shipping. Additional cleaning, known as mechanical cleaning, may entail separating out non-coal material in a liquid medium, which led to the widely used term “washing.” The washing medium is an aqueous chemical solution prepared to enhance wettability and dissociation of the coal and non-coal materials or to produce specific gravities calibrated higher than water alone.
Coal Production Line Benefits
Coal preparation is processing of run-of-mine coal, the raw coal coming out of the mine, in order to enhance its characteristics for shipping and ultimate utilization. Benefits of coal preparation may include:
- removal of non-combustible material, whose weight raises shipping costs and which can increase wear in coal grinding equipment and boilers;
- enhancement of deliverable heat content;
- removal of unwanted minerals that can foul boilers or damage the environment if entrained in boiler emissions or ash;
- suppression of dust and improvement of handling and shipping qualities.
