Broyeur à boulets de ciment
The cement ball mill is mainly used for the grinding of cement clinker and mixture materials in the cement production process. It can be used for open-loop grinding, and it can also be used for circulating loop grinding with a classifier. The cement ball mill has the characteristics of high grinding efficiency, large output, low energy consumption, and easy adjustment of the fineness of the grinding product.

30.3-16.3
Application:
Used in the grinding of finished products in cement plants, and also suitable for grinding various ores and other grindable materials in metallurgy, chemical, electric power and other industrial and mining enterprises.
Features of cement ball mill
1. High grinding efficiency and low energy consumption;
2. The fineness of the product is uniform, and the product is smooth;
3. Low vibration, low noise, good equipment sealing, no dust spilling, clean environment, meeting environmental protection requirements;
4. Special cement mills can be designed and manufactured according to users’ different requirements for grinding fineness and output.
Cement ball mill working principle
Cement mills usually adopt edge drive, generally equipped with 2 to 4 bins. The materials enter the ball mill No. 1 bin evenly from the feeding device through the feeding screw. There is a stepped liner inside the bin, which contains different specifications of grinding media, and the cylinder rotates. Centrifugal force is generated to bring the grinding medium to a certain height and then fall down, which will impact and grind the material; after the material is coarsely ground in the No. 1 warehouse, it enters the next warehouse through the partition liner, which is lined with a corrugated liner or a flat liner. , There is a grinding medium to further grind the material; the powdery material is discharged through the discharge grate to complete the grinding work.
The cement ball mill is composed of a feeding device, a discharging device, a barrel of the mill, a moving device (reducer, small transmission gear, motor, electric control) and other main parts.
