The scene processing mill pinion shaft grinding of small problems

Ball mill is widely used in cement, Portland products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, such as glass ceramic industry consumption of all kinds of ores and other materials may be grinding stop dry or wet grinding. Each startup equipment of ball mill in carrying load, so about 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, increase equipment trouble rate, reduce the using life of the 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 attack metal fatigue, produce for variant; Bearing inner ring and the shaft or the bearing outer ring and bearing housing is clearance fit, wear by relative motion. Once appear this problem, seriously affect the normal consumption of the equipment. Prosperous nation in the 21st century with carbon nano polymer materials field repair. According to different equipment, different running condition, different wear condition, adopts the corresponding repair process, can be fast, simple and effective to repair, especially because of the high polymer material concession, has always insisted on 100% of the contact area, prevent the formation of the fit clearance, make the repaired equipment life that go beyond the new equipment, basically deal with ball mill axial wear problem. An enterprise maintenance staff found that ball mill reducer pinion shaft bearing vibration compared, and the bearing temperature rise from time to time. Emergency stop under this condition, the overhaul 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, now wear after the size is 268 mm, 12 mm diameter size of wear, uneven wear depth of 6 mm, some wear more and more serious. Equipment of high speed compare with, per minute up to 960 r/min, after repair concentricity of the request is very high. During this period, the enterprise management through the network and telephone counseling meticulous understanding of the online repair technology, other online repair technology are turning demand site, but the enterprise equipment basic does not have turning condition, and about the depth of the wear depth of 6 mm are helpless. Choose sauvy industrial ball mill for business wear problem eventually stop performing live online quick fixes. Sauvy carbon nano polymer repair technology is how to complete the scene the fast repair the detailed operation process is as follows: ( 1) Baked oil: appearance using acetylene oxygen to stop baking oil, operation time control between 10 to 15 minutes; （ 2) Exterior burnish: appearance using the polishing machine polishing rough, clean, progress 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, according to the calculation results to reconcile SD7101H; （ 4) Harmonic average good SD7101H daub to bearing an appearance, and rapid tooling equipment in place; From harmonic SD7101H to tooling equipment in place, 10 minutes to complete the whole process; （ 5) SD7101H natural curing after 30 minutes, stop heating 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 to stop. Tooling appearance to do a simple disposal after the end of removal, verify the size of repair, remove the appearance to the redundant data. Bearing heating to specify the temperature at the same time, the device in place quickly, repair at the end. On-site repair ball mill pinion shaft bearing a picture
