APPLICATION TECHNICAL MANUAL OF XINHAI MINING MACHINERY PRODUCTS 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.

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. - 24 -
