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 is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
Pulverizing solid fuel to powder enables its drying and transport for combustion in large furnace sizes. Fine grinding increases the fuel exposed surface area while simultaneously drying and controlling its distribution. These are integral steps to efficient, low emissions combustion which are optimized together with boiler thermal performance.
