Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment mainly consists of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system.
As the “black blood of industry”, coal is usually ground into micro size powder, which can ensure a high combustion efficiency. However, different degrades of coal are used in different application with different requirements. Hongxing Machinery can supply all kinds of coal mills to process coal ores like hard coal, woody lignite and lignite, anthracite coal and petroleum coke. Besides, Hongxing coal mills can be installed with other assistant equipment such as the bag-type dust collector and electric magnetic iron mover, to meet the requirements of any industry.
In order to control the energy production of the plant, the coal flow into the furnace is an very important factor. Unfortunately, it is not possible to measure the coal flow from the coal mill to the furnace. The coal flow out of the mill is often estimated based on the incoming coal flow. In case of a fault in the coal mill the plant operator would need to take accommodating actions as fast as possible. Fault detection in the coal mill is consequently important.
