Gold, Iron, Copper, Silver Plant Use Overflow Type Ball Mill

Ball Mill is the key equipment for grinding materials to get the product as per the requirement of process, used widely in electric, ferrous (non-ferrous) metal, nonmetal mining, chemical & building material industries. 

Ball Mill could be sorted as following:
As per the grinding media:ball mill, rod mill and AG mill (without grinding media)
As per material discharging mode: wet grinding mill, dry grinding mill & overflow mill.
As per driving mode:side & central driving. The former is more popular now.
As per driving configuration:
a. Asynchronous motor driving: Asynchronous motor + Reducer + Pinion + Girth gear
b. Synchronous motor driving: Synchronous motor + Air clutch +Pinion + Girth gear
c. Asynchronous motor + reducer +diaphragm coupling
Main bearing:  adopting slide bearing, rolling bearing or sliding-shoe-bearing as per requirement.
Liner:  adopting wear-resistant metal liner, rubber liner, magnetic liner and alumina liner (high aluminum lining brick). Following items as per options: inching driving device, high & low pressure lubrication station, spraying lubrication device of gear, jacking device  

Working principle of ball mill:
There are many grinding medium balls inside the continuous rotating drum (there are many rods inside the rod mill). The continuous feeding material is broken by the shooting balls which are coming from a certain height of the wall of the drum; The falling medium and material would produce irregular slip and roll during the rotation of the drum, and the material is pulverized fine by the grinding effect among medium, drum-lining and materials. The dynamic material level different is produced by continuous forced material charge and discharge, consequently more and more fine material is slow out from the drum, and finish the grinding process inside the drum.
