Raymond Mill Installation And Maintenance Of Common Sense

Raymond Mill Installation And Maintenance Of Common Sense
Raymond Mill main structure:
Raymond Mill mainly by the host, analyzers, blower, finished cyclone, cyclone powder and air tube. Among them, the host from the rack, inlet volute, blade, roller, grinding ring, cover composition. Swimming in order to meet the needs of users, very solid machine frame design, therefore, laying the foundation for regular removal equipment is not only to the device on a hard flat surface can be true and, if the fixed installation, belt machine, the best hit concrete foundation. Installation, please refer to installation diagram below. Put stability first, and a fixed host, and then install the fan and connecting duct, and other cyclone. Must be used between the flange asbestos rope, rubber or foam seal, and then use alkyd white Houqi (commonly known as lead oil), strict sealing for the job in order to avoid leakage of production.
Raymond Mill Working Principle:
Work, will need to crush the material from the hopper into the machine casing to join the side of the machine, rely on the host plum hanging roller device shelves, the revolution around the vertical axis, while its rotation, the rotation of centrifugal force, grinding Roll out swinging, pressed on the grinding ring, the shovel blade to grind the material between the roller and grinding ring, because of the rolling roller compacted to achieve the purpose of crushing.
Raymond Mill winnowing process:
After grinding the material, fans will be blown in the White case, the blowing powder, placed in the grinding chamber through the top of the analyzer for sorting, fine through coarse material into the grinding raymond mill chamber and re-grinding, compliant with the fineness airflow into the cyclone collector, collected and discharged through a powder outlet, is finished. Airflow from the top of a large cyclone collector tube back into the return air fan, air duct is circular, and in the flow under negative pressure, circulation air duct to increase air flow between the host partly by the exhaust fan and exhaust pipe into the small cyclone collector device, for purification.
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. Maintenance is as follows: spindle oil time to class time, but must note that the cup of oil loss or loss of oil is not too slow, they should immediately wash the oil channel, plus 50 # machine oil, oil cup top position in the spindle, spindle base bearing, roller bearing axle with grease gun filling each class 3 # lithium grease once every six months apart bearing analyzer washed once, add a little 3 # lithium based grease, lithium plus fan bearing room grease.
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 motor, feeding too little will affect production. Feed size: hard materials less than 15 mm in diameter, preferably, soft material for the 20 mm diameter, non-bulk material added to the machine.
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. Located on the exhaust pipe outlet exhaust valve, transferred into the feed opening can be no dust emitted. Air volume is small, thin high. It should be noted, the wind is too small, the host is easy duct below the sediment material, please adjust.
5. Fine adjustment, based on the size of the material, hardness, moisture content, the proportion of different degree of processing are different thickness, can be adjusted at the top of the analyzer, high speed, fineness, low speed, low fineness. 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 10mm.
7. Stop, stop feeding, the system still continue to operate, continue to make residual abrasive grinding, about a minute, turn off the main motor and the motor analyzer, stop grinding work, and then stop the fan motor to blowing off the powder residue.
