Cylinder ball mill

Introduction
Cylindrical ball mill  is the key equipment for grinding after the crush process,is composed of feeding part, discharging part, turning part and driving part. The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.
Features
1.Structure is simple. The length of cylinder is much longer than the diameter. The whole cylinder is divided into 2 to 4 cabins with different lengths and function
2. Uniform ore particle size and less overgrinding
3. Easy maintenance and long service life.
Application
It is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Working principle
Cylindrical ball mill is horizontal cylindrical rotation device, driven by brim gearwheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball. After the secondary grinding, material is discharged from the discharging mouth. Then the whole grinding process is ended.
