Castings And Forgings High Abrasive Resistance Ball Mill Steel Balls For Mining
1. Introduction of steel balls of ball mill castings and forgings
Ball mill steel ball is ball mill equipment grinding material medium, through the ball mill between the steel ball and the friction between the ball and material grinding effect, important basic parts, especially precision industrial steel ball plays a huge role in the development of national economy. Widely used in cement plant, power plant and so on. High and low chromium multi-element alloy steel ball, high and low chromium multi-element alloy casting.
