The ball mill’s high pressure oil system is designed to lift the trunnions during start-up by supplying high pressure oil. The high pressure pump is programmed to shut-down after the mill has been running for a predetermined amount of time. The high pressure pump pumps oil through the high pressure supply lines to the trunnion bearings.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Modern dry-process cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kg-cl of thermal energy and 100 kWh/mt of electrical energy. Older plants with inefficient systems, combined with operational and maintenance failure, tend to have much higher energy consumption.

Due to their high separation efficiency and its high circulation factor, VRM tends to produce cement with a steep PSD curve unlike those generated by ball mills. Cement with a steep PSD is one with a high water demand. To address this issue, VRM manufacturers have come up with a more conventional raw mill VRM design. Investment Cost
