[Introduction] : An overflow ball mill with rolling bearings, high efficiency and energy saving.
[Capacity] : Up to 160t/h
[Improvement] : Rolling bearings replace slipping bearings to reduce friction; easy to start; saving 20-30% of energy.
The transmission of straight type ball mill uses large double row spherical roller bearings replacing sliding bearings, which largely reduces the friction and easy to activate. It saves 20-30% energy
Corrugated liner is used, which increases the contact surface of balls and ores. It strengthens the grinding effect. It also has lift capacity to the ores, reducing the energy consumption.
Large discharging throat and large production capacity.
The whole rake is applied for small type ball mill with diameter under 2.1m, which is suitable for civil construction and equipment installation.
Spray lubrication device, ensuring the reliable lubrication of large and small gears.
The main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates 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. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With a simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
