Product Description
Overflow ball Mill
The wet ball mill for mining is divided into lattice ball mill and overflow ball mill according to different mining methods. It has the advantages of high crushing ratio, good reliability, strong adaptability and large processing capacity. It is widely used in mineral processing, metallurgy and construction，chemical and other industries, is the main equipment for grinding operations.

Working principle
Overflow ball mill is used in concentrator. The discharging is due to the fact that the hollow axis diameter of discharging end is slightly larger than that of feeding end, resulting in a certain inclination of pulp in the mill towards discharging end. When the height of pulp surface is higher than the lower busbar of inner diameter in the discharging inlet, the pulp overflows and discharges from mill. This is a non-forced high-level ore discharging, the discharging speed is slow, so the ore resides in the
machine for a long time, the efficiency of grinding media is also low, so the overgrinding of the overflow ball mill happens very often, and the handling capacity is lower than the lattice type of the same specification. Generally, it is usually used for fine grinding or two-stage grinding.

Technical characteristics
▲ The transmission type of ball mill include edge drive, center drive, multi-point meshing edge drive, etc. The drive mode is asynchronous motor + reducer + pinion + big gear and synchronous motor + air clutch + pinion + girth gear.
▲ In general, the support mode of static and dynamic pressure bearings at both ends is adopted, and the fully closed self-aligning 1200-line contact'rocker-type'bearing is adopted. The support mode of static and dynamic pressure of single and double sliding or full static pressure support can also be adopted.
▲ The open girth gear is designed by the US AGMA standard, equipped with a reliable gear cover and an automatic glycerol spray lubrication device.
▲ Cylinder is the key part of the mill. The finite element analysis is carried out by computer to ensure the reliability of the mill.
▲ Large and medium mills are equipped with slow drive devices.
▲ Large and medium mills are equipped with lubrication stations of high and low pressure.
▲ Control and protection system is controlled by PLC.
