Overflow ball mill

Product introduction

Except for the different production conditions and ore discharge method of the grid ball mill, the overflow ball mill can be configured according to the grid ball mill standards. In addition, the overflow ball mill also has the following features:

Performance Features

1. The engine uses large double-row spherical roller bearings instead of sliding bearings, which greatly reduces friction, makes it easy to start, and saves 20-30% of energy;

2. The grooved annular lining plate is used to increase the contact surface of the ball ore, strengthen the grinding effect, and have the ability to lift the ore, reducing energy consumption;

3. The bearing uses static and dynamic pressure Bearings, operation is smooth and reliable.

4. The overflow ball mill below 1.2m can be made into an integral frame design. The entire mill is installed on an integral welded frame. The frame is connected to the foundation for easy installation and debugging ( The same can be said for grid ball mills).

Product structure

How it works

The working principle of the overflow ball mill is mainly supported by rolling bearings. The cylinder is driven by the transmission device to rotate, so that the materials and steel balls rotate together with the cylinder, and complete the dropping, impact, impact and self-grinding operations in the cylinder to realize the material grinding. When the material is continuously fed, it will be under pressure, causing the material in the cylinder to gradually be discharged to the discharge end. When the slurry is higher than the lower edge of the hollow shaft at the discharge end, the material will flow overflowing by itself, and the steel at the discharge end will The balls and coarse materials will return to the mill through the anti-spiral blades and continue grinding.
