Rod mill

Rod mill

Principle

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 rods 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.

Features

Smaller curvature of conical cap of the rod mill enables the regular movement of the steel rod in mill. Larger diameter of discharging hollow shaft is easy for maintenance, and can reduce the slurry liquid and realize rapid discharging.

Even particle size and little over grinding.

Application

Mainly used for coarse grinding operation. Suitable for the fine crushing and coarse grinding in the first stage grinding, especially for processing brittle materials.
