Grinding Cylpebs widely used in cement plant. With the special heat treatment system, LONGSHENG cylpebs has been achieved good properties, high hardness, martensite or bainite metallographic structure and lowest wear rate .good wear resistance, etc.
Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm. According to different chromium content, the grinding ball can be divided into three kinds, namely low, medium and high chromium balls.
