Stirred media mills are indispensable members of the mineral processing flowsheets, which are requiring regrind and fine grinding applications. Such a high utilization of these technologies comes from their energy-efficient operation over the …

In mineral processing, 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, not to ...
