Grinding Mill for Calcium Carbonate Powder

Grinding Mill for Calcium Carbonate Powder

The production line adopts the international popular continuous production process: ball mill and air classifier system. The technological process mainly includes crushing (generally using two-stage crushing), grinding, classifying, packaging, magnetic separation, transportation, lifting, etc. After the ball mill can be parallel or series multiple classifier at the same time to produce more than one size of the product.

Working principle: The raw material is fed into the hollow cylinder through the hollow shaft neck for grinding. The cylinder is equipped with grinding media of various diameters (steel ball, steel bar or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, the medium and raw materials in the cylinder under the action of centrifugal force and friction force, as the cylinder reaches a certain height, when its own gravity is greater than the centrifugal force, it will escape from the cylinder body wall and drop or roll down, smashing the ore due to the impact force. At the same time, the sliding motion of the grinding medium also produces grinding effect on the raw material during the rotation of the mill. The ground material is discharged through a hollow journal.

Features: Wide range adjustment, good grain shape (low abrasion value), stable quality, large scale (the maximum size of a single line is 1250 mesh, about 100,000 tons).
