Raymond mill bearing locking do you know why?2015-02-06
Raymond mill bearing locking is generally caused by large bearing rotation friction. Why the bearing friction is so large? Today, Shanghai Clirik Machinery, 25 years in Raymond mill producing, introduces the reason cause bearing friction.
Bad state of bearing lubrication, the Raymond mill bearing works under the conditions of lack of oil or no oil will reduce the flexibility of bearing operation. The bearing will has many difficulties in slide. Too much sludge and dirt inside the bearing, the sludge and dirt occupy many space of the bearing, while a smaller space occupied by the use of grease, which results in poor bearing lubrication state; it is difficult to rotate the shaft. Too small bearing clearance can lead to difficulties in bearing operation, the bearing locking.
To solve Raymond mill bearing locking solutions, it need regularly add appropriate quantitative bearing lubricant, and periodically clean the bearing cavity foreign bodies and impurities. In addition it need increase the bearing clearance and the bearing operating flexibility. What is more, we need pay attention to Raymond mill maintenance and periodic maintenance.
1, for the raymond mill normal operation, the user should develop equipment "equipment maintenance safe operation of the system" to ensure the long-term safe operation of the mill. At the same time have the necessary repair tools and grease and the corresponding accessories.
2, after a period of use, maintenance should be carried out, while roller grinding ring blade overhaul replacement of wearing parts such as processing, grinding roller device before and after the use of the connection bolts and nuts should be carefully examined to see if there is loose phenomenon, whether to add a little grease.
3, roller device use time more than 500 hours or so to replace the roller, the roller of each rolling bearing kit must be cleaned, damaged parts should be replaced, fuel pumps and hand tools available grease gun.
4, fineness adjustment, according to the size of materials, hardness, moisture content, different proportion of different fineness processing, adjustable top analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, the output will be reduced accordingly, if it is below standard debugging fan speed, users can be flexible.
5, roller mill scrap ring limit, the remaining minimum wall thickness of not less than 10mm.
6, Raymond mill stop, stop feeding, the host continues , residual abrasive grinding continues, after about a minute, turn off the master motor and the motor analyzer, stop grinding work, which then stop the fan motor to blow residual powder.
