Difference between Crushing and Grinding 911 Metallurgist

17/02/2017· That is to say, the total work done in the machine is proportional to: a (m — p) + b (m — q) + c (m — r) — d (m — s) – e (m — t) = d s + et — ap – bq — cr because a + b + c = d + e = 100 This gives us, then, a very simple rule for finding the work done in a grinding machine, which we may best describe by a numerical example Suppose that we wish to compare the efficiencies of the grinding effected by two machinesHammer crushers and rotary breakers Grinding is conducted in mills There are three grinding stages, coarse grinding (hundreds of microns), fine (tens of mictons) and ultrafine grinding (<10 microns) Tumbling mills, rotary breakers, and pendulum mills are mostely usedCrushing Vs Grinding Minerallurgy08/07/2016· UNTIL THE THIRD THEORY OF COMMINUTION of “Work Index” method of determining crushing and grinding mill size was introduced, there was no way of accurately figuring the most applicable, most economical size of crushing and grinding mill Naturally, with little or no factual operating data correlated in useful form, it was easy enough, even for the most experienced, to arriveEquipment Sizing: Crusher or Grinding Mill
