Energy saving ball mill
Principle
The main component is a cylinder with diameter and length at a reasonableproportion. Driven by the transmission device, the cylinder rotates with thematerials fed from the cylinder inlet and crushed by the falling impacts andautogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outletand the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.

Features
Large double-row self-aligning roller bearing with lowfriction force is used to replace sliding bearing, and is easy to start with energy saved by 20-30%.
Grooved ring plate liner is used to increase the contactsurface of ball and ore, strengthen the grinding, lift the ores, and reduce the energy consumption.
Technical Parameters
Overall frame is adopted for small size ball mill (Dia <
2.1 m) which is much more convenient for civil work and installation.
Oil mist lubrication device guarantees the lubricationof all gears.
Application
Generally used in the grinding of ores with finerfineness.
