Cement Grinding Machine Selection: Vertical Roller Mill VS,
For roller press, the grinding parts are two rollers of the same size. The materials fall vertically from the top to the two rollers to form the material bed. Under the extrusion force of the two rollers, materials are ground to fine particles. There are two transmission modes of roller press, namely double drive, and single drive. The double drive roller press is the more popular type. The transmission device of a single drive roller pressCement Roller Press - Roller Press In Cement Plant,,The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process.
