Characteristics of Grate ball mill：
The hollow axis adopts the cast steel;
The lining can be replaced;
Rotating adopts casting rolling gear;
The barrel body is wearable;
The ball mill runs smoothly;
Works realiably.
Working Process of Grate Ball Mill：
Through material hollow shaft spiral the material is sent to the first mill chamber, in which there are ladder liner or corrugated linings, with steel balls of different specifications in it. When cylinder rotating, centrifugal force will produce steel ball fall down from a certain height, thus impacting and grinding the materials. After coarse grinding in the first chamber, materials enter into the second chamber through a single diaphragm. In this warehouse with flat lining board and steel balls in it, materials are further grinded.
