The uptake of HPGR technology by metallic mineral processors has involved a number of suppliers but primarily KHD Humboldt Wedag and Polysius for the HPGR machines and ABB for the drive systems. Normally, it is the HPGR supplier''s prerogative to choose the drive supplier; the end user normally buys the HPGR with the drive systems included.
WhatsApp An HPGR with a brand new set of rollers starts operation with identical torque and speed. Over time and based on various operating factors ( ore characteristics, operating pressure, feed etc.), the rollers experience different wear rates. With RollXtend the load provided by both rollers can be fine tuned by the operator based on the wear ...

HPGR feed increases and hence, results in a finer product. Because the total throughput of the grinding systems remains equal the size of the HPGR has to be increased to be able to handle both fresh feed and recycle. The fineness along the roll axis follows a certain gradient according to Figure 9. Reasons for

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
