a.Raymond mill use and maintenance
1. Grinder in the use of the process, there should be a fixed charge of personnel, the operator must possess the necessary skills. Milling machine installed before the operator must carry out the necessary Jishu training, so that understanding of Raymond mill machine Yuanlixingneng familiar with operating procedures.
2, for the grinding mill normal equipment should be established “safe operation of equipment maintenance system” can ensure the long-term safe operation of the mill, also have the necessary maintenance tools and grease and the corresponding accessories.
3, Raymond machine used for a period of time, maintenance should be carried out, while ring roller mill for blade repair replacement of wearing parts such as handle, roller device in use before and after the connecting bolt nuts should be carefully examined to see if there are loose phenomenon, whether to add a little grease.
4, roller devices around the time more than 500 hours to replace the roller, the bearing of the roller kit must be cleaned of all, the damaged parts should be replaced, fuel pumps and hand tools used butter gun.
5, fineness adjustment, according to the size of materials, hard and soft, moisture content, the proportion of different thickness and degree of processing is different, adjustable at the top of the analyzer, high speed, small and high, low speed, fine low. Improve the fineness of the output will be reduced accordingly, if it is below standard fan speed when debugging, the user can flexibly.
6, ring roller mill scrap the limit, the minimum remaining wall thickness of not less than 10mm.
7, stop, first stop the feed, the host continues to Japanese sample, to continue the grinding abrasive residue, about one minute, turn off the main motor and the motor analyzer, stop grinding work, and then stop the fan motor, for blowing the powder residue.
b, Raymond mill operating improvement trends
Raymond Grinder in the powder industry will be mainly to the high reliability, energy saving, accurate, automated condition monitoring and automatic control direction. Can use the SCR power supply, AC variable speed control, oil lubrication, shock absorption and other measures, and a condition monitoring and control devices such as computers. Which require high reliability, enhanced by mechanical principles of rationalization of grinding ring, the wear resistance under the gland, etc., to improve the machine working in a continuous state of a bearing lubrication before. Automatic condition monitoring and automation control needs to increase in the Raymond machine within intelligent electronic control systems, automatic control of materials in and out, grinding, and the other quantitative. Operators operate only between the control button. Materials need to be strengthened to improve the precision grinding of machine accuracy.
