Horizontal grinding mills

In mineral processing, horizontal grinding mills must endure vibration, shock loads, moderate to slow speeds and a high concentration of particulates. In these conditions, contamination, loss of lubricant and even improper mounting techniques can all lead to failures for pinions or trunnions. And, of course, cause costly downtime and repairs

Sugar 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. Standard sugar mill practise limits the bearing pressure to about 10 MPa.
