Grinding miller

Industrial grinding machine, a type of grinder, is a cylindrical device used for grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. It is a key piece of equipment for grinding crushed materials and widely used in the production lines for powders such as cement, silicates, refractory, fertilizer, glass ceramics, etc. There are two ways for the industrial grinding machine to grind materials ---- the dry way and the wet way. And according to the different expelling ways, this grinding miller can be devided into tabular type and flowing type.

 Working Principle of the Grinding Miller

The grinding miller is a horizontal cylindrical rotation device with two chambers and grids, which is driven by the brim gearwheel. Through the feeding inlet and the hollow shaft, the material goes into the first chamber uniformly. In the first chamber, there are stage liners and ripple lines as well as the steel balls with various specifications. The centrifugal produced by the rotation of barrel takes the steel ball to a certain height, and then under gravity the ball drops down , thumps and grinds the materials. After the coarse grinding in the first chamber, the materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel balls. The materials will get further grinding in the second chamber. At last, the materials will be discharged through the discharging screen.

Structural Characteristics of the Ball Grinding Mill

This grinding miller is mainly composed of the feeding part, discharging part, rotation part and driving part (including gear box, small transmission gearwheel, motor and electric control device, etc). The hollow shaft is made of the cast steel, whose inner liner can be changed. The big rotation gearwheel is made by the processing of cast hobbling which has the wearable liners in the drum, so it has the good wear resistance.
