Classification and Characteristics of Cement Grinding Mill

Dec 04 2014

Cement grinding mill is mainly used for grinding raw materials into powders in cement production line. It can also be used to grind other ores and grinding materials in metallurgy, chemical industry, electric power and other industrial and mining enterprises. It is capable to both dry product and wet product powders. This article will introduce you the classification and characteristics of cement grinding mill.

1. Ordinary cement grinding mill

It is suitable for medium and small scale raw material grinding system. Generally, it is used in powder-circuit grinding systems for selecting powders at outside of the grinder.

2. Wind sweep cement grinding mill

Wind sweep cement grinding mill is characterized by short and fat. The diameter of the hollow axis for transporting materials is big. The gap between every board grate of storehouse is large. There is no grate board at the discharging port, so there is little obstruction and the speed of wind in the grinding room can reach more than 5M/s. A large amount of heat can enter into easily, improving the drying capacity.

3. Trail-discharging and lifting type cement grinding mill

Compared to wind swept cement grinding mill, the difference of this type cement grinding mill is that materials directly arrive at the end of the grinding room after being dried, then they are discharged by machine, and are sent to the powder selection equipment by elevator. At last, coarse materials are back to the grinding room for re-grinding.

4. Center-discharging and lifting type cement grinding mill

Center-discharging and lifting type cement grinding mill in the combination of trail-discharging and lifting type cement grinding mill and wind swept cement grinding mill. It is equal to the secondary-circuit grinding system. There is a drying room at the frond of this type cement grinding mill, providing good drying effect. Raw materials enter into the equipment from its head, and the coarse materials come back to the coarse grinding room and fine grinding room from its head and tail. The finished products are discharged at the center of the grinding system and are sent to the powder selection machine by elevator.
