overflow type: ore discharged through hollow shaft. grid type: ore discharged through grid plate. peripheral type: ore discharged around the cylinder. types on the basis of drive mode. center drive ball mill: the drive power device is in the center of the fuselage, and the motor realizes the operation of the ball mill through the reducer. In operation, the hollow shaft in the center of the ball
steel rod is usually used as grinding medium in rod mill, while steel ball is used as grinding medium in ball mill. the steel balls are in point contact with each other, and the steel rod of rod mill is in line contact with each other, so their working features are obviously different. medium filling rate.

the grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of the overflow type ball mill. the overflow ball mill discharges the ore by the gravity flow with the slow speed, so its production capacity is relatively weak, and because the material stays in the ball mill for a long time, it is easy to cause the over-grinding phenomenon.
usually, the concentrator chooses the grid type ball mill in the one-stage grinding and the overflow type ball mill in the two-stage grinding. generally, the upper limit of particle size of the grid type ball mill is 0..m, so it is often used in the one-stage grinding, and formed the
