The choice of mine mill is one of the main equipment of material crushing.

　　Choose a mine mill maintenance and overhaul 1. When the mill is running continuously, after thorough cleaning the oil, all lubricants should be released. In the future, oil will be replaced once every 6 months while in progress. 2. The lubrication status and oil level should be checked at least every 4 hours. 3. When the mill is operated, the temperature rise of the main bearing lubricant does not exceed 55 ° C. 4. When the mill is operating normally, the temperature rise of the transmission bearing and the speed reducer does not exceed 55 ° C, no more than 60 ° C. 5. The gear and pinion of the gear are stable, no abnormal noise. Adjust the gap in time if necessary. 6. The ball mill is stable and there is no strong vibration. 7. The motor current should have no abnormal fluctuations. 8. Each connection is fasteningless, no oil can be passed, no water, no leakage. 9. Add steel balls in a timely manner according to the wear. 10. If you find an abnormal situation, stop the repair immediately. Regular work in the maintenance plant.

　　The quality of maintenance work directly affects the running speed and service life of the ball mill. In order to find hidden dangers in time, ensure that the mill is operating normally, in addition to daily maintenance, it is necessary to stop grinding regularly. For important components, such as air mandrels, main bearings, cylinders, reducers, carefully check the detailed record of the size gear. Determine and arrange the intermediate and overhaul programs according to the shortage of defects. The choice of mine mill is one of the main equipment of material crushing. High manganese steel lining is usually used. Life is generally only 6-12 months, resulting in a large number of metal consumption. Only the metal minerall plant consumes 80,000 tons of liner per year. Magnetic lining can be widely used in a metal mine ball mill. Since the working principle is different from ordinary liner, the service life is far more larger than the ordinary liner.

　　The working principle of the magnetic lining is: due to the magnetic field of the lining, when the mill is operated, the fragment in the ore is adsorbed on the working surface of the lining, and the surface is not required to be directly worn, using magnetic liner. Instead of high manganese steel pads will bring huge economic benefits to your business. The magnetic lining is used in the ball mill of the ferromagnetic material having the following advantages: 1. The liner working surface can adsorb a layer of ferromagnetic material to form a protective layer, so that the surface of the liner is not directly wear, so that the lining life is prolonged by 5 to 8 times; 2. The price of each lining is twice the high manganese steel liner, which reduces the cost of the lining to 25-40%; 3. Reduce the time and workload of replacement and repair, improve equipment operating rate; 4, can be self Magnetic adsorption is attached to the cylinder, no need or notBolts, easy to install and maintain; 5, the thickness of the manganese steel liner can increase the volume of the cylinder, improve the milling of mill processing; 6. The protective layer has sound insulation effect, reducing noise; 7. Magnetic for ten years.
