Coal comminution and sizing ScienceDirect

Jan 01, 2013· Depending on the nature of the coal and of the planned processing, during mining the largest lumps may be broken to a topsize as large as 200 mm, or as small as 50 mm. The preparation plant will then apply sufficient crushing to control the topsize of the preparation plant feed, followed by screening or classification to separate the coal feed by size for later processing.

Feed Coal an overview ScienceDirect Topics

In light of the changed characteristics of coal, raw coal has to be crushed to 13 mm before treating it (13–0.5 mm) in HM cyclones. The fines (<0.5 mm) in the washery generally amount to around 25% at present. After crushing the coal to 13 mm, the quantity of fines will increase, this will have a detrimental effect on coal preparation. The percentage of fines may go up to 30%.
