Long-Cylinder Ball Mill
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.
Features
Cylinder diameter is much larger than the diameter. The cylinder is divided into 2-4 bins with different lengths and
functions by the bulkhead.
Application
Mainly used in cement plants, and can also be used for grinding other materials related to the industrial sector.

Special Single & Double Shaft Vertical Mill for Graphite
Principle
The machine consists of cylinder, disc agitator, transmission device, frame, etc. The cylinder is filled with some
grinding media (such as steel ball, corundum ball or gravel). Driven by the V-belt, the disc agitator rotates slowly,
and the grinding media and materials do multidimensional circular motion and spinning motion. As the media and
materials rotate up and down in the cylinder, the materials are effectively grinded by the heavy pressure of grinding
media, rotation friction, impact extrusion and shear force. The machine has the comprehensive features of the tower
mill, stripping machine and sand mill.
