Size Reduction In Ball Mill

Praticle Size Reduction in the Ball Mill Drug

· The size distribution produced by the ball milling of various crystalline and non crystalline materials showed that initially there was a fairly even distribution over the size range up to 355μm However as milling proceeded two distribution modes developed one at about 90μm the persistent mode and one at about 250μm the transitory mode Unlike the work of Heywood 1 on coal
