In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. Coal mill is the most commonly used in coal mine production line of the most basic equipment,and it mainly consists of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. Working process of fote machinery coal mill is as follows: raw materials are sent to grind mill through feeder and rotate with mill cylinder after the hot air entering the grinding mill, then coal and hot air carry out heat exchange.Coal mill is the coal pulverized coal crushing and grinding into mechanical, it is an important auxiliary equipment of pulverized coal furnace. Quarry crushing and screening equipment malaysia Coal grinding process is the process of coal was broken and its surface area increased. To add new surface area, we must overcome the molecular bonding force between the solid, and requires energy expenditure. Pulverized coal into coal in the coal mill, mainly through the crush, crush and pulverization three ways. Crushing process energy consumption of the province. Trituration process is the most energy consuming. All sorts of coal mill in milling process are both the above two or three ways.And we also have other mining machines, such as stone crusher plant, mini granite crusher and portable rock crusher, hammering machine and so on.
