cement rolling press
Our rolling mill is a new type of cement grinding equipment developed on the basis of advanced technology. Its grinding system integrates rolling, dispersing, separating, drying and powder separation. In addition, when used with a ball mill, it can be used in a variety of processes such as pre-grinding, mixing, semi-finished grinding, finished grinding, and the like. Due to changes in the grinding principle, the mill and its grinding system have more advantages, such as a 50-100% reduction in energy consumption and a 100-300% increase in productivity.
Advantages of cement roller press
- Thermal surfacing has been adopted to make the maintenance of the wear layer more convenient. At the same time, the number of microcracks is greatly reduced, and the service life of the roller surface is not less than 8000h. It is very easy to maintain the roller surface.
- Aviation hydraulic technology makes the hydraulic system more reliable and stable.
- With the hydraulic system and automatic control system, it can complete the load control of the main drive motor, the deviation control of the roller pitch, automatic deviation adjustment and fault diagnosis.
- The matched powder separator has the ability of dispersion, classification and drying, which can reduce operating costs and improve work efficiency.

Working principles
The motor drives the grinding disc to rotate through the reducer, and the material falls from the feeding opening to the center of the grinding disc, moves to the edge of the grinding disc under the action of centrifugal force and is crushed by the grinding roller, and the pulverized material overflows from the edge of the grinding disc and is simultaneously from the nozzle ring ( Wind Ring) The high-speed upward hot air flow is brought to the high-efficiency classifier integrated with the vertical mill. The coarse powder is sorted by the separator and returned to the grinding disc for re-grinding; the fine powder is ground with the airflow and is collected in the system. Collected in the dust device, that is, the product. The coarse-grained material that has not been taken up by the hot air flow and the accidentally entered metal parts fall from the wind ring, are scraped off by the scraping plate, and are fed again into the grinding mill by the externally circulating bucket lifter.
