China Energy-Saving Wet Overflow Ball Mill for Gold Ore Plant

China Energy-Saving Wet Overflow Ball Mill for Gold Ore Plant

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. 

1. Usage:
Raw material mill is used widely for grinding (both drying and grinding) cement raw material and other materials in building material, metallurgical, electric and chemical industries.

2. Sorts and Features:
a. Common Raw Mill It is used for small & medium-sized raw materials separating system outside the mill.
b. Air-swept Mill The feature of Air-swept mill is short and thick in shell, wide in diameter of inlet &outlet trunion, large in grate gap area of diaphragms between drying chamber & grinding chamber, no grate plate in mill outlet. therefore, air speed inside of mill could reach 5m/s due to small resistance and drying capacity is strong since large amout of hot air could get in.
c. Outlet Discharging & Lifting Cycle Mill Comparing with Air-swept mill, material, passing through the drying chamber, are discharged at the outlet of grinding chamber by mechanical way, and then fed into separator by elevator which would return the coarse material to mill again for cycle grinding.
d. Middle Discharging & Lifting Cycle Mill From the view of drying, it is the combination of Air-swept Mill & Outlet Discharging & Lifting Cycle Mill; from the view of grinding, I workssimilar to secondary stage cycle grinding system. At the front end, it has drying chamber with high drying efficiency. Materials are fed from mill inlet, returned material from separator are fed through mill inlet & mill outlet into rough grinding chamber & fine grinding chamber respectively.
 
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.
