Learn mill operation preparation, start-up and shutdown sequence using a ball mill now place a lot, but before the 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, ore grading machine, 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. Flotation equipment described mixing bucket using a flotation machine mixing bucket using a range of equipment and features a mixing device ready for use concentration ≤3.5 ≤30% and the proportion of pulp and flotation reagent. The machine has a small power consumption, high flow centrifugal classifier, stir, Shanghai grader, simple operation, long service life. Second, the structure and working principle is mainly from the base, motors, pulleys, vertical axis, tank, stirring impeller, bearing body and other components. Work by the motor, pulley, transmission power, so that the lower end of the vertical axis of rotation of the impeller stirring, then add water, add agents, feeding, stirring. Third, the main technical parameters of mixing drum groove diameter: Φ1200mm tank depth: 1500mm effective volume: m3 impeller diameter: Φmm impeller speed: r / min Motor power: kw four flotation equipment mixing bucket operation Note 1, work , the spindle clockwise, not reverse. (From the top down view) 2, when the work spindle first run, then 2/3 of the amount of water injected into the tank, and then feed mixing. 3, before work, you must check whether the vertical axis perpendicular to the bottom surface. 4, in the production process is stopped before the operation, you must first open the drain holes at the bottom of the body will remain in the tank drained more than mine, powder classifier, and then to stop in order to avoid precipitate slurry impeller deposition, affect the start of the next machine and safe operation. Five body with grease lubricated bearings, grease once per shift. Sixth, the vulnerability of tapered roller bearings 7311 air classifier, Beijing grader, North mine Zhongcheng Zhongcheng from Shenyang North mine equipment Limited. Shenyang North Mine Zhongcheng equipment Limited (sybkzc.com) (www.sybkzcjq.com) strong, credible, in Shenyang, Liaoning province machining industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the public into North mine into the brilliant and you work for a better future!
