Dry Ball Mill
The dry ball mill is mainly used for the grinding of finished products and raw materials in cement plants, and is also suitable to grind various ores and other grindable materials, for mining, metallurgy, electric power and chemical industry.
| Production capacity | 21-155TPH |
|---|---|
| Specific surface area | 330-380m²/kg |
| Power | 800-3550 kw |
The materials are uniformly sent to the first compartment of dry ball mill by the feeding device through the feeding trunnion. The first compartment of dry ball mill contains stepped lining board or corrugated lining board, and steel balls of different specifications. The centrifugal force generated by the cylinder rotation will bring the steel balls to a certain height and then drop down, which will have a pounding and grinding effect on the materials. After the rough grinding is finished in the first compartment of dry ball mill, the materials will enter into the second compartment through the single-wall partition, which is lined with flat lining board and steel balls to further grind the materials. The powder material is discharged through discharge grates, then the grinding operation is completed.

1. With high stability, won a number of new patents: Double-sliding-belt tube mill of CHAENG is the first one in China to solve the problem that grinding mills cannot continuously work due to the high temperature of sliding-belt shaft bush at the discharge end, and won national patent for utility models with patent No.: ZL201020285841.9. Many examples prove that CHAENG cement ball mill can run steadily for a long time.
2. Novel structure, strong production capacity: CHAENG cement mill adopts the latest and unique streamline design of the world, to reduce the ventilation resistance, increase the effective volume, make discharge easy, and improve the output of the mill. Lining plate in the mill adopts combined structure design, and different lining plate structures are used in different stages of raw material mill, so that the grinding efficiency is improved greatly. Its material drying capacity can reach 10%～15%.
3. Specific surface area of finished product is 3300-3800cm²/g: Specific surface area of the cement produced by CHAENG cement mill is 3300-3800cm²/g. Compared with other mills in the same industry, CHAENG cement mill has advantages of high-fineness product, larger specific surface area,quick hydration reaction, and fast strength development.
