A comparative study on the effects of dry and wet grindingKnow More
nbsp 0183 32 In a feasibility study dry grinding of magnetite ore for particle production from 50 mm to 90 181 m was performed by using HPGR Results showed that two stages HPGR followed by dry grinding in a closed circuit with 7 and 1 mm screens could reduce energy consumption by...

nbsp 0183 32 However in ore processing applications it is conventional to use the 80 wt passing size P 80 to represent the particle sizes at different stages in comminution This is easy to measure i e weighing the separated fractions after sieving although two P 80 values can have vastly different size distributions and therefore differ greatly in mean particle sizes...
