Wet overflow ball mill

The main component of the wet overflow ball mill is a cylinder with a smaller diameter and a larger length. It is supported by a rolling bearing and rotates slowly through a transmission mechanism. The material is fed from the feed 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.

In the original production process of tungsten concentrate, in order to pursue a larger processing capacity, a grid-type ball mill was used in the second-stage grinding process. In the end, it was found that the output was not up to standard and the equipment was severely damaged, so Huston’s wet overflow ball mill was used. The overflow ball mill does not require forced discharge of ore, and the slurry overflows automatically, which reduces equipment consumption and energy consumption. The discharge particle size is small, the grinding particle size qualification rate is greatly improved, and the cost is controlled.
