Cylindrical Energy-Saving Overflow Ball Mill with Rolling Bearing
Principle
The main component is a cylinder with smaller diameter and longer.
Driven by the transmission device, the cylinder rotates slowly with the
materials fed from the cylinder inlet and crushed by the falling impacts
and autogenous grinding of the steel balls and ores in the cylinder. Due to
the continuously feeding materials, the pressure pushes materials to the
outlet and 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; in dry grinding, the materials
are taken out by air. 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.
engineering construction and equipment installation;
Large ore outlet and large capacity;
Oil mist lubrication device guarantees the lubrication
of all gears.
Features
Large double row self-aligning roller bearing with low
friction force is used to replace sliding bearing, easy to
start with energy saved by 20-30%;
Grooved ring plate liner is used to increase the contact
surface of ball and ore, strengthen the grinding, lift the
ores, and reduce the energy consumption;
Overall frame is used, which is convenient for civil
Application
Generally used in the grinding of ores with finer
fineness.
