Cement Industry: Ball mills are extensively used in the cement industry for grinding raw materials, clinker, and additives to produce cement. ... They are widely employed in both wet and dry grinding processes for the comminution of materials such as gold, copper, iron, and lead-zinc ores. Pharmaceutical Industry: Ball mills are utilized in the ...
Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 μm are beneficial to …
— Ball mills in HPGR-Ball mill circuits tend to have more installed capacity than their counterparts in AG/SAG-Ball mill circuits. This is because the product size distribution from AG/SAG mills tends to have more fine material than the HPGR circuit product ( Morrell, 2009, Morrell, S., 2011 ) and hence need less ball mill power.
