SBM vertical mill are used in the cement industry for grinding cement raw material, coal, petroleum coke, blast-furnace slag, pozzolana and cement. In order to extend the life of our vertical mill, you should do some maintenance .
1, vertical mill in the use process, there should be regular staff responsible for the custody of the operator must possess a certain level of technology. Milling machine before installing the operator must carry out the necessary technical training, so that to understand the principle of mill performance, are familiar with operating procedures.
2, for the vertical mill to normal, should be developed equipment "equipment maintenance safe operation of systems" can ensure the long-term safe operation of mills at the same time have the necessary repair tools and grease and the corresponding accessories.
3, vertical mill used for a period of time, maintenance should be carried out, while roller grinding ring Blade repair of replacement of wearing parts such as processing, grinding 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 lubricant.
4, roller devices of the time more than 500 hours or so to replace the roller, the pairs of rollers each bearing kit must be cleaned in time to replace the damaged parts, fuel pumps and tools can be used to manually add butter gun.
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.
