  • HPGR High Pressure Grinding Rolls

    HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

  • High pressure grinding rolls (HPGR) Metso

    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.

  • Sugar Mill Bearings

    Mill Bearings Bearing Pressures. The maximum pressure that a bearing can withstand is mainly a function of the bearing material. The bronzes that are common in sugar mills have a recommended maximum bearing pressures of up to 100 MPa for phosphor bronze and 50 MPa for tin-bronzes.

  • What's normal: The role of temperature in bearing applications

    The ball bearings used in most electric motors are pre-greased, shielded ball bearings. Normal motor bearing operating temperatures range from 140° to 160°F. As in all bearing applications, this measurement should be taken at the bearing outer ring. If the outer ring is inaccessible, take the measurement at the housing and add 15° to 20°F

    Many bearings use three layers; a soft aluminum outer layer, a layer of copper in the middle and a steel backing plate. Such tri-metal bearings use copper, which is a softer but slicker metal than aluminum, to give the owner a last line of defense before the bearing wears down to the steel or fails completely.
