According to the materials and methods of discharge, optional dry ball mill and wet lattice-type ball mill. Energy-saving ball mill, using self-aligning double row spherical roller bearings, Yunnan selected iron mill, a small running resistance, energy-saving effect is remarkable. Barrel portion, the discharge end of the cylinder in the original section of the cone cylinder increases, both to increase the effective volume of the small ball mill, and make more rational allocation barrel medium. The products are widely used in non-ferrous metals, ferrous metals, non-metallic mineral processing field and chemical, building materials industries for grinding use. Ball handling ability with the ball filling rate increases, increase the filling rate increases the chances of the ball crushing mill ore and ore autogenous grinding effect. Filling ball mill rate of 45% is the maximum load, with the filling rate of increase in its load dropped significantly when more than 45%. This is mainly because the filling rate increases, the ball is lifted from the throwing point, the ball hit the red fall together to accelerate the rotation center point of near and over, their moments together to shorten and become O negative, Its Ball (ORE) drop falling combined impact load torque required by large becomes 0 until turns driving force behind the barrel rotation (ie, beyond the center point of the joint effect of selected iron mill, combined torque is negative). Wet overflow type ball mill is by way of discharge discharge end of the hollow shaft diameter is slightly larger than the feed end of the hollow shaft, resulting in the pulp mill for the discharge end of a certain inclination. When the pulp surface height is higher than the minimum inside diameter of the discharge port bus, then the overflow discharge pulp mill. This is a non-forced high material level of discharge, grinding adequate, good grinding effect. Generally applicable to finely grinding or two in the second paragraph of grinding.
