Four Main Working Steps of Coal Slime Dryer

Coal is one of the main fuels in power generation plant and our daily lives. The byproduct-coal slime is featured with high water content and holding capacity, high viscosity and low heat value, and that makes the storage and transportation very difficult. So the coal industry in the past was not able to make use of the coal slime. Now the modern technology makes the coal industry capable of deep processing of raw coal and dealing with the large quantities of coal slime, coal slime becomes one main raw material for coal product. The coal slime product is fit for industrial and home use, the industrial use means the power generation plant.Process flow of coal slime dryer: 1. Guiding section. Upon entering into this section and blending with the high temp, negative pressure hot air, moist material will be promptly evaporated much and thanks to the shovelling plates, the material is tough to be bond together but led into next section.2. Cleaning section. Due to the work of shoveling plates, a vaporific curtain by the material will come into being and the drum internal walls will be bond with the material which will then be cleaned off swiftly by the cleaning device hereby, during which the coal slime lumps and agglomerates will also be crushed. Consequently, the heat exchange degree, ratio and the drying speed will all be increased.3. Shoveling section. Also called low temp drying zone. The coal slime hereinto remains slacked status with lower water content which means no possibility of bonding, however, after heat exchanging, the material will have met the requirement for water content and then go into next sections.4. Discharging section. Within the drying drum, there is no shoveling plate available. But the dried material will slide to the outlet.It consists mainly of such systems as heating, scattering, feeding, conveying, drying, dust collecting, electric controlling and crushing.Henan Fote Heavy Machinery Co., Ltd is a joint-stock mining machinery...
