Inspection and maintenance during the use of the ball mill

The ball mill is a grinding machine commonly used in mineral processing. Therefore, the reasonable maintenance of the ball mill is an important condition to ensure a high operating rate and long service life of the ball mill for sale. The maintenance work of the ball mill in the beneficiation equipment should be combined with the operation and maintenance, often The successful move is accompanied by a good maintenance plan and maintenance record. Formulating a complete set of maintenance plan and maintenance policy is one of the important tasks in the production of the new concentrator. The maintenance plan is thorough and the maintenance personnel's attitude is serious. The degree and the correctness of the maintenance plan are obviously reflected in the economic benefits. In order to smoothly carry out the planned maintenance and repair work every time, the equipment maintenance record should be made in time. The operation status of each equipment and the effect after maintenance are recorded in detail. For example, the main bearing, grid plate, lining plate and other easy-grinding parts are carefully recorded. The number of replacements, and the use of these records as a history of the equipment in order to predict the life of the components. And plan to replace parts (spare parts). The number of repairs and time can be determined according to the operation of each grinding machine, but also depends on Wearing parts or easy-to-wear parts - wear level of the lining. Maintenance of the grinding machine In addition to routine maintenance inspection, the ball processing equipment of the mineral processing equipment is regularly carried out with minor repairs, medium repairs and overhauls. 1 minor repairs. Generally 1-3 Once a month, the main maintenance project is to inspect, repair or replace worn parts such as mill liners, feeder heads, pinions, couplings and pads, feed tubes, motor bearings Wait. Check each fastener; inspect the oil pump and lubrication system, clean and change oil, temporary accident repair and minor adjustment of wear parts, small change and trapping. 2 medium repair. Usually 6-12 months, its overhaul In addition to all the minor repairs, the project also needs to clean and adjust the various parts of the equipment, such as repairing the rotating gears, and replacing a large number of easy-to-grind parts. 3 Overhaul. The cycle is generally about 5 years, and its maintenance In addition to all the items included in the repair, the project also replaces the main bearing and large gears, inspects, repairs or replaces the cylinder and end caps, repairs the foundation, and aligns or refills the grout.
