Development of large-scale flotation machine ball mill liners currently, 50 m3 flotation machine (coal washing equipment equipment) in China has been rapid application, solve the technical problems of many companies and industries. Application of 50 m3 flotation machine total more than 200 units, involving non-ferrous metals, ferrous metals, non-metals, gold and solid waste utilization, etc. ball, creating greater economic benefits. 160 m3 successful development of large flotation machine, the overall strength of the flotation device, competitiveness and international influence further. 160 m3 and 130 m3 has been used as a number of the company's new large-scale concentrator device of choice. Many mining enterprises promote the use of mineral processing mill, and achieved good results. Learn mill operation preparation, start-up and shutdown sequence using a ball mill in place now with a lot of ceramic ball, but the first ball mill What precautions do you have? Here to explain: First, prepare ball before the operation: 1, check whether someone. 2, check whether the oil level is appropriate, add insufficient. 3. Check the ball filling ratio meets the requirements. 4. Check all parts are loose and reliably tighten. 5. Check the hole cover tightly secured reliably. 6, check and rectify the leak powder phenomenon. 7, the first test run or the long-term should be poured a small amount of lubricating oil after stop grinding, press the "jog" revolution, confirming that no abnormal phenomenon. 8, and related operations staff contact, allowing the signal to start after starting the mill. Second, the sequence starting mill: 1, the starting powder output device. 2, starting mill. 3, start the feeder. Third, the order of mill downtime: 1, stop feeding the machine. 2, stopped ball. Long-term stop grinding balls and materials should be emptied. 3, the material on the machine discharge after their stop. These are the preflight preparation, start-up and shutdown sequence.
