How to effectively improve the grinding efficiency of ball mill is an important problem. In this paper, 10 methods to improve efficiency are summarized. 1. The hardness, toughness, dissociation and structural defects of the raw ore determine the difficulty of grinding.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
