Product Description
Polysius high-pressure grinding rolls have been used successfully in the grinding of raw materials and binding agents. Polycom HPGR grinding is based on the principle of supplying the material to be ground to two counter-rotating rolls via a feed system. These rolls draw the feed material into the gap between them, where it is ground under high pressure. A hydro-pneumatic system generates the required grinding pressure of up to 250 MPa.
The grinding process produces compacted cakes containing a high proportion of fines, as well as coarser particles with cracks in them. These compacted cakes are broken up, separated and, if necessary, subjected to further grinding.
