Raymond mill use in maintenance rules

1,Raymond mill in addition to the upper end of the sliding bearing spindle, the rest of the drive section rolling bearing, it must run in good lubrication condition, otherwise it will damage the bearings and shorten life. Maintenance as follows: spindle refueling time once per shift, but it must be noted that the oil cup oil found no loss or loss is too slow, you should immediately wash the oil channel, plus 50 # machine oil, oil cup position at the upper end of the spindle, the spindle pedestal bearings, roller shaft bearings with grease gun filling each class 3 # lithium grease once a parser bearings cleaned once every six months apart, add a little 3 # lithium grease, fan bearings room plus lithium grease. 2, non-metal block into the machine, otherwise it will damage the grinding roller and grinding ring, and even center hanger. 3, feeding should be uniform, not erratic. Excessive feeding blocked duct will reduce the yield, easy to burn out motor, feeding too little will feed production. Feed size: hard material is less than 15 mm in diameter are suitable, soft material diameter of 20 mm, non-bulk materials added to the machine. 4, air volume control: the fan into the wind pipe located on the control valve, generally open to the maximum position, according to fineness, yield requirements appropriate adjustments. Valve exhaust outlet is located on the exhaust pipe, transferred inlet at no dust spray can. A small amount of wind, fineness. It should be noted, wind is too small, easy to precipitate within the host material beneath the duct, make the appropriate adjustments. 5, fine adjustment, based on the size of the material, hardness, moisture content, different specific gravity, thickness of the process is different, you can adjust the top of the analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, output will be reduced accordingly, if it is mainly the fan speed debugging, the user can be flexible. 6,Raymond roller mill scrap ring limit, the remaining minimum wall thickness not less than 10mm. 7, stop, stop feeding, the host continues 盍, the residue of abrasive proceed milled about a minute, turn off the main engine of the motor and motor analyzer, stop grinding work, which then stops the blower motor, in order to purge the remaining powder.
