Ball mill ball is ball mill equipment grinding material medium, through the ball mill ball ball and material between the collision between the friction produced mill strip effect, important basic parts, especially the precision industrial ball in the national Ball mill ball Economic development plays an important role. Widely used in cement plant, power plant, etc. High and low chromium multielement alloy steel ball, high and low chromium multielement alloy casting.
