ball mill

Detailed Product Description

Ball mill (dry or wet process)
Application:
Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Working principle:
The 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. Then the whole grinding process end.
Structure:
The machine is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The rotation big gearwheel is made by cast hobbling processing and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
