Gold Mining Rock Crusher 900*2100 Grinding Machine Grinding Small Ball Mill
Ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grid type and overflow type due to different ways of discharging material.

Ball mill machine is edge drive, center discharge, and ball mill machine has inlet and outlet device, end cover, hollow shaft, barrel, large and small gears, reducer, motor and other components.
Working process of the ball mill is that the material enters the cylinder one after another in the hollow shaft of the feeding end cover, and when the cylinder rotates, centrifugal force and friction are generated, so that the medium (steel ball) and the ore rise to a certain height with the cylinder wall, and then fall down parabolically or cascade down with their own weight, and the grinding of the ore is mainly realized by the impact force when the crushing medium falls down and the grinding effect when it moves, and the movement of the ore in the cylinder is realized by the pressure that is constantly given to the ore. The movement of the ore in the cylinder is achieved by the pressure of the ore. Finally, the ore is discharged from the hollow shaft of the discharge end cap. In wet grinding, the ore is carried away by water, and in dry grinding, the ore is carried out by the airflow pumped out of the cylinder. The rotation of the ball mill is driven by the motor through the speed reducer, the pinion gear rotates, the pinion gear engages the large gear installed on the cylinder and decelerates, the large gear rotates at an even speed, and the cylinder starts to work.
