Size selection requirements and feeding device of mine mill

- Aug 13, 2019-

Mine mill with the particle size of grinding material selection, material by hollow shaft ball mill feed end into the cylinder body, when the ball mill cylinder rotation, grinding medium because of inertia and centrifugal force effect, the effect of friction, making it attached to the cylinder liner was taken away by cylinder, when was brought to a certain height, be cast down by its own gravity, the whereabouts of the grinding medium like projectile of cylinder body of the material to break. 

The material of mine mill enters into the mill bin uniformly through the feeding device through the feeding hollow shaft spiral. There are ladder lining plates or corrugated lining plates in the bin, and steel balls of various specifications are installed inside. Centrifugal force is generated by the rotation of the cylinder to bring the steel balls to a certain height and then fall down, resulting in heavy hitting and grinding effect on the material.After the material is coarsely ground in the warehouse, it enters into the second warehouse through the single-layer compartment plate, which is inlaid with flat lining plate and contains steel balls to further grind the material.The powder is discharged through the unloading grates to complete the grinding operation.
