Types Of Coal Mill Used In Cement Plant

Types Of Coal Mill

• LUM vertical roller mill is used to pulverize and dry coal before it is blown into the power plant furnace in the coal-fired power plants.
• As we all know coal production line is with serious pollution, In order to provide a environmental friendly coal grinding mill for customers, MTW trapezium mill is designed with sealed structure.
• Raymond mill is used for crushing coal resources. Relying on the impaction between high-speed Raymonds and materials to realize the crushing effect, the Raymond coal mill has the characteristics of simple structure, high efficiency, high ratio of reduction, and so on.

Coal Mill Fineness Analysis

Every coal mill is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index (HGI), based on a defined raw coal size, moisture content, and desired fineness level.  It may also be used to confirm the influence of coal fineness on combustion performance and to evaluate carbon loss.

Coal Mill In Cement Plant

Coal powder after grinding by coal mill enter in to the rotary kiln with each other with cement raw meal for burning. Coal powder has unique strict demand in fineness. The completed size is 0.0445mm. Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment is mainly consisted of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. So coal grinding mill is widely used in cement plant.
