Roller press for cement plant is a grinding equipment of grinding brittle material, and is mainly consist of the two rollers with same speed, and rotating relatively. The material is discharged from the feedwell of the upper roller and enters the gap between the rollers. Under the 50-300MPa high-pressure grinding force, the material bed is squeezed, and pressed material become into the flat material with dense and full of cracks.

The roller type of roller press is similar to the roller crusher, but the difference is that the pressure between the rollers is much greater than that of the latter, so the material processed by the roller press contains much less fine powder than the roller crusher.

The following characteristics of roller press for cement plant compared to ball mill:

1.     High grinding efficiency, increasing production and energy conservation. In the ball mill, material is suffered the pressure and shear, which the combined effect of these two forces. In the roller press for cement plant, the material is basically only under pressure.

2.     Reduce steel consumption. Grinding cement, the yield wear of ball mill production is 300-1000g / t; using roller mill grinding system, the production of abrasion 0.5g / t, so it can meet the requirements of white cement grinding.

3.     Low noise. The noise of ball mill is more than 110dB, while the roller press for cement plant is about 80dB.

4.     Small size, light weight, small footprint, easy installation, or even the overall installation.

As the roller applied force of roller press for cement plant is too large, there will some problems about roller press for cement plant such as roll surface material is loss and wear, the bearing is easy to damage, the reducer gear is premature rupture and other problems, reducer gear premature rupture and other issues. In addition to the stringent requirements on the operation of the process, such as the feeding material column is required dense and full, and maintain a certain feeding pressure, appropriately control the amount of feedback material, applicable grinding process system configuration requirements, or it can not play the superiority of roller press for cement plant.

In summary, the characteristics of roller press for cement plant is high pressure, slow speed, full material, material bed crushing.
