Due to the manufacture, the end of the discharge pipe in the hollow journal of the discharge end cap is flared, and an annular retaining ring is usually also installed at the root of the hollow shaft, so that the slurry leaking from the bolt hole of the end cap can be prevented. Flow into the bearing. At the same time, a spiral is cast in the discharge pipe, and the direction of the spiral is opposite to that of the mill, thereby preventing the steel ball and the ore block from being discharged out of the machine with the slurry. However, the unit has a low volume production capacity per unit volume and is prone to over-grinding.
Due to the long grinding time of the machine, the ore can be fully ground in the machine and the residence time is longer, so the grinding product is finer. Therefore, the grinding machine is usually used as a stage grinding and is suitable for concentrate. By re-grinding, a qualified product with a finer particle size can be obtained.
