The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.



1. The jack-up device of wet grate ball mill makes maintenance easy.
2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill.
3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance.
4. The oil-mist lubrication device guarantees reliable performance of bearings.
