Common sense of Raymond mill maintenance Comparing with ball mill, raymond mill features high efficiency, low power consumption, small size, a one – time investment and widely used in small barite, calcite, potash feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bleaching, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc whose mohs hardness is not greater than 9.3 and humidity is below 6%. Raymond Mill is chiefly consist of the milling method, analysis method and dust removal method. Raymond Mill is chiefly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. Raymond mill can produce powder from over 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain, clay, basalt, gypsum etc.The final size is between 613micron and 440 micron(0.613mm 0.044mm). Raymond mill use and maintenance of common sense: 1. The aircraft except the top of the sliding bearing spindle, the other transmission parts for rolling bearings, lubrication must therefore be in good running condition, otherwise it will damage the bearings and shorten life.

2 Non-metal block into the machine, otherwise it will damage the grinding roller and grinding ring, and even center hanger. 3 The feeding should be uniform, not suddenly much less ignored. Excessive feeding blocked duct will reduce the yield, easy to burn out the engine, feeding too little will affect production. 4 Air volume control: the intake pipe is located on the blower air volume control valve, generally open to the maximum position, according to fineness, yield requires an appropriate adjustment. 5. Improve the fineness, the output will be reduced accordingly, if it is mainly the fan speed when debugging, the user can flexibly. 6 Ring roller raymond Mill scrap the limit, the minimum remaining wall thickness of not less than 10 mm. 7 Stop, stop feeding, the system still continue to operate, continue to make residual abrasive grinding, about a minute, turn off the main engine and the engine analyzer, grinding work, and then stop the engine fan to stop blowing off the powder residue.
