Horizontal Mining Process Equipment Overflow Grate Discharge Ball Mill

1. Summary

Overflow discharge ball mill is one of the traditional grinding equipment. It has been widely used in cement, silica, new building material, ferrous and non-ferrous metal, fertilizer, glass, ceramics and other industries for power grinding and milling process. Ball mill can grind various stones, mineral ores and materials with dry type or wet type. Due to different ways of discharging, there are lattice type and overflow type ball mills for usage. Ball mill is one of the key milling equipment for the raw material which has been primarily crushed by jaw crusher or hammer crusher.

2. Working principle

Ball mill is horizontal cylindrical rotation grinding device. The ball mill is driven by brim gear wheel (outer gear), and there are two or more grinding chambers. When the material was fed into first chamber through the quill shaft spiral uniformly, as there are stage liners and ripple liners as well as grinding steel media balls inside it, the drum (shell) rotates so as to generate centrifugal force and bring the grinding steel balls to certain height and then the balls drop down by gravity, and this impact and grind the raw material to small particle. After the primary coarse grinding process, the ground material goes into the second chamber through segregate screen. Inside the second chamber, there are flat liners and grinding media balls which grind and impact the material further. After the secondary grinding and milling process, the powdered product was discharged through the grid plate to accomplish the complete grinding process.
