High-pressure grinding roller mills are used to grind raw materials. Damage to the bearings of grinding rollers results in disruptions to the production process. In order to minimize this risk, Schaeffler was commissioned to conduct vibration measurements as part of a pilot project supported by the machine manufacturer (OEM).

ادامه مطلبHigh 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.
