Tube mill

 

Description of Tube Mill

 

Tube mill is a key equipment for further grinding after the materials were first broken. Tube mill is widely applied in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metal ore dressing and glass ceramics production industries, etc. The machine is used for dry or wet grinding a variety of ores and other grinding materials.

 

Tube mill working principle

 

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 tubes. The shell rotates so as to generate electricity, and this force brings tube 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 tubes. After the secondary grinding, material is discharged from the discharging mouth. Then the whole grinding process is ended.

 

 

 

 

Tube mill structure:

 

The machine is composed of feeding part, discharging part, turning 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 turning gearwheel adopts casting hobbing process 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 tube mills and wet tube mills for choice.
