Steel Ball Grinding Ball forged ball for Ball Mill use 65Mn 75Mn 40Cr 42CrMo4 50Mn

Grinding body in ball mill
Low chrome steel ball is the most important grinding body in ball mill, which is called grinding steel ball in foreign countries. Steel ball is the world's crushing industry and even the foreseeable future of the first wear-resistant materials, in 2010, only a domestic mineral processing industry that consumed about 2 million tons of various materials of steel ball, and the cement industry in 2010 is expected to consume a record 300,000 tons.
