Mill use of the process, should have permanent staff in charge of, the operator must have a certain technical level. Mill prior to installation of the operating personnel must carry out the necessary technical training, Raymond Mill, Principles of performance, are familiar with operating procedures. In order to make the mill should be developed equipment "equipment maintenance safe operation of the system can ensure the mill long-term safe operation, have the necessary tools for maintenance and grease and the appropriate accessories. Raymond used for a period of time, maintenance, roller mill ring blade and other wearing parts repair and replacement, roller device in use before and after the connecting bolts and nuts should be carefully examined to see if there is a loosening The lubricants whether to add a little. The roller device using more than 500 hours or so to replace the roller, roller kit, rolling bearings must be cleaned and damaged parts should be replaced refueling tool can be used manually pumps and grease gun. Fineness regulation, are also different depending on the size of the materials, hard and soft, moisture content, the proportion of different processing thickness can be adjusted to the top of the analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, the output will be reduced accordingly, and if it is mainly the fan speed when debugging, the user can flexibly. Grinding roller mill Central scrapped the limit, the remaining minimum wall thickness of not less than 10mm. Raymond machine stop, stop the feed, the host continues to He, residual abrasive continue to mill, about a minute, you can close the host motor and analyzer motor to stop the grinding work, then stop the fan motor, in order to blow the net residual powder.
