Ball bearings are mainly divided into:. Radial ball bearings are the most commonly used bearings for radial loads, especially in the single row version. By virtue of the geometry of the raceways they can also withstand axial loads (to be verified for each application) even bidirectional, at the same time reaching high rotation speeds and, with adequate lubrication, low noise levels.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems. Mills are available in both light-duty and heavy-duty construction to meet your specific requirements.

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.
