To be checked before starting the grinding machine bearings, transmission equipment. Including connecting bolts, large gears connecting bolts, a material conveying equipment, safety facilities. And clear obstacle to the functioning of debris around the grinder mill. You should follow the order of "discharge convey Equipment → mill → feeding equipment " to start grinding machinel product line, and shutdown according to the opposite order.

In the operation period shall be strict compliance with operating procedures. To achieve constant attention to the grinding machine running sound is normal or not, check the lubrication of bearings and bearing temperature is normal, regular checks of the motor temperature and current, check the functioning of the transmission equipment. After the grinder mill outage, check the main bearings, hollow shaft, cylinder, reducer connections and other important components, and wear problems are discovered timely processing.

Normal operation and maintenance work, the choice of lubricants, use, storage is very important. Because the role of lubricants can avoid direct contact with the surface of grinding machine parts, reducing friction, reducing wear and tear. While taking advantage of thermal conductivity of the oil can pass the heat generated by friction, it should be kept clean and a certain degree of viscosity of lubricating oil, while oil to ensure adequate and smooth flow.

If you need to stop grinding machine for a longer time, you should put the poured out, to avoid the tube bend. In cold areas, to release bearing cooling water in winter, in order to avoid Frost Crack.

Raymond mill is a common industrial powder equipment, and the main factors you should pay attention to have been listed here:

1, The spindle refueling time should for each class plus, but it should be noted that the oil found in oil-cup there is no loss or loss is too slow, they should immediately wash the oil Road, together with 50 # machine oil, oil cup top position in the spindle, spindle base bearings, roller bearing axle with grease gun for each class notation 3 # lithium based grease once a parser bearings cleaned once every six months apart, add a little 3 # lithium based grease, fan bearings room plus lithium Grease.

2, forbidden piece of metal into the machine, otherwise it will damage grinding roller and grinding ring, and even center hanger and so on.

3, feeding should be uniform, non-erratic. feeding too much will be blocked duct, lower output, easy to burn out motor, feeding too little is not good also. Feed size: hard material in the diameters less than 15 mm, preferably, soft material diameter of 20 mm, large pieces of material is strictly prohibited to join the machine.

4, air volume control: in the fan on the intake manifold air flow control valve, generally open to maximum position, according to fineness, yield requirements appropriate adjustments. Is located in the exhaust pipe on the exhaust exit control valve, transferred to feed the mouth can be no dust emitted. Air volume is small, thin high. It should be noted, wind is too small, the host within a duct beneath the easy precipitation of materials, please be adjusted appropriately.

5, fineness adjustment, according to materials, size, hardness, moisture content, the proportion of different degree of processing of different thickness, adjustable top of the analyzer, high speed, fineness high, speed low, thin low. Improve the fineness, the output will be reduced accordingly, if it is mainly the fan speed when debugging, the user can flexibly.

6, roller mill scrap ring limit, the remaining minimum wall thickness of not less than 10mm.

7, parking, the first stop feeding, the host continues the mood, so that residual abrasive continued milling, about a minute, you can disable the host motor and motor analyzer, stop grinding work, and later stopped fan motor, the net in order to blow residual powder.
