Raymond mill dust selection method includes a complete set of milling equipment several important equipment Mill (Raymond), fans, crushers, dust and other components. And in the choice of these types of equipment, Zhengzhou Lei Machinery Co., Ltd. First to introduce the dust under Raymond selection. Raymond filter material is based on the nature of dust to choose to buy the mill, which is mainly in two ways in terms of flammability and charged dust resistance, dust flow and friction. Dust combustion or explosion ignition source is usually caused by friction sparks, static electricity sparks, hot particles caused by coal mills, where the charge of damaging. This is because the fiber filter is usually easy charged, if the dust is charged at the same time easy to produce sparks, so easy for combustible dust charged as coal, coke, aluminum powder and magnesium powder, etc., should be Select retardant and conductive filter media. When the dust flow and strong friction 85 mills, wear dust filter bag will directly reduce the service life. In common dust, aluminum, silicon powder, coke powder, charcoal, and other sintered ore is a high abrasion dust. For wear dust filter should use good wear resistance. Wear parts and form dust filter is varied, based on experience. More wear and tear in the lower bag, this is because the upper bag filtration rate is low, gas dust concentrations of small reasons. 4r mill | Lei Machinery (Online) | mill provided by Zhengzhou Machinery Co., Ltd.
