Straight cylinder energy-saving overflow ball mill

The working principle of the straight-cylinder overflow ball mill is supported by rolling bearings and rotates slowly through the transmission mechanism. The material is fed from the feeding end of the cylinder. In the cylinder, the material is crushed due to the impact and self-grinding of the steel balls and the ore itself. Due to the continuous feeding of materials, the pressure causes the materials in the barrel to move from the feeding end to the discharging end. The slurry is higher than the lower edge of the hollow shaft at the discharging end and overflows by itself. The hollow shaft is equipped with anti-helical blades, which can return overflowing steel balls and coarse ore blocks into the mill. The equipment structure of this new ball mill consists of the feeding part, main bearing, rotating part, transmission part (large and small gear devices), air clutch, main motor, slow transmission device, jacking device, lubrication system, electronic control system, etc.

A copper dressing plant in Yunnan found that although the grinding efficiency in the pre-selection work was high, the material particle size was large, equipment consumption was heavy, and the cost remained high. After repeated discussions and selections, Huston’s straight-cylinder energy-saving overflow ball mill was finally selected. Although the output has declined, it fully meets the needs of the dressing plant. Moreover, Huston ball mill has good material, low wear, and simple structure. It uses corrugated lining plates to increase the ball-ore contact area, strengthen the grinding effect, and reduce energy consumption. Ultimately, we achieve the goals of reaching standards, production and basic cost control.
