The scene to solve the shaft grinding of ball mill pinion - bearing small problems

Ball mill is widely used in cement, Portland products, new building material, refractory material, fertilizer, black and non-ferrous metal ore dressing and glass ceramics production industry, of all kinds of ores and other materials may be grinding of dry or wet grinding. Each startup equipment of ball mill in carrying load, so for the motor, reducer, and the size of the bearing and gear and other parts and equipment is very big, the influence of frequent start increasing the load of the component, increases equipment failure rate, reduce the service life of equipment. Ball mill in overloading, overlap of high speed high torque at low speed under the start, and under the action of vibration equipment, radial impact, bearing chamber or bearing a metal fatigue, produce permanent deformation; Bearing or bearing outer ring and inner ring on the shaft bearing chamber clearance fit, resulting in relative motion develop blemishes. Once appear this issue, seriously affecting the normal production of the equipment. In the 21st century, developed countries adopt more carbon nano polymer material line repair at the scene. According to different equipment, different running condition, different wear conditions, adopt corresponding repair process, can be fast, simple and effective to repair, especially due to the high polymer material rolled back, always keep 100% of the contact area, avoids the production of fit clearance, make the repaired equipment life even more than new equipment, fundamentally solve the problem of ball mill axial wear. An enterprise maintenance staff found that ball mill reducer pinion shaft bearing vibration is larger, and the bearing temperature rising. In this case the emergency stop, overhauling pinion shaft bearing, found that small gear shaft support side bearing damage, and bearing wear, originally the bearing with a diameter of 280 mm diameter bit, now wear after the size is 268 mm, 12 mm diameter size of wear, uneven wear depth of 6 mm, with partial abrasion is more serious. The speed of the equipment is higher, per minute up to 960 r/min, after repair concentricity requirement is very high. During this period, the enterprise management through the Internet and telephone details about the online repair technology, other online repair technology are turning control need, but enterprises don't have the condition of turning, but also for the depth of the wear depth of 6 mm are baffled. Final choice sauvy industrial enterprise ball mill wear problem for on-site online quick fixes. Sauvy carbon nanometer polymer repair technology is how to realize the rapid repair of concrete operation process is as follows: ( 1) Surface baked oil: oil using acetylene oxygen for baking, operation time control between 10 to 15 minutes; ( 2) Surface polishing: use the rough grinding polishing machine will surface, clean, improve sauvy carbon nano polymer SD7101H cohesive force. The whole grinding process control in 20 minutes or so; ( 3) Sauvy carbon nano polymer SD7101H dosage calculation, and according to the calculated results to reconcile SD7101H; ( 4) Will reconcile good SD7101H evenly to the bearing surface, and rapid tooling installed; From the harmonic SD7101H to equipment installed, 10 minutes to complete the whole process; ( 5) SD7101H natural curing after 30 minutes, in the heat curing, the curing time is 2 hours. ( 6) SD7101H curing is complete, ready to heating bearing and remove the tooling work, both at the same time. Do simple tooling after the removal of surface processing, verify size of repair, remove to the surface of the excess material. Bearing heating to specify the temperature at the same time, the rapid installed, after repair. On-site repair ball mill pinion shaft bearing a picture
