A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

Flow control gates are designed to provide controlled discharging of bulk solids from silos and bins. Installed on airslide conveyors, flow control gate valves are used for shutoff, flow regulation and metering. A flow control gate valve has two chambers inside. Lower chamber supplies fluidization air to upper chamber. It works like an airslide conveyor, keeps continuous material flow.

Control of low speed mills. As PF flow to the furnace is not measured, generally feeder speed is used to estimate the PF flow. However, in ball and tube mills, storage capacity for the coal is large and hence, speed of the feeders does not provide a good indication of the coal flow transported by the primary air to the furnace [9]. The coal ...
