(1) first stop feeding equipment; (2) stop the main motor; (3) to stop conveying equipment; (4) stop (the powder) and dust collection equipment; (5) Stop lubrication and cooling water. 6, the emergency stop ball: ball mill operation, one of the following incidents, stop grinding processes: (1) the main bearing the vibration amplitude exceed 0.15mm; (2) main bearing temperature not greater than 60 ?, if it exceeds this value or continues to rise; (3) linings, Manhole, rotary component and the other connecting bolts loose or fall off; (4) compartment plate or discharge grate plate, the material sieve blockage of production; (5 ) ball mill parts or linings had broken off; (6) off the oil lubrication system failure occurs; (7) Ball Mill reducer and motor abnormal phenomena (such as the engagement is not normal, temperature is too high), does not meet the reducer and Motor specification of the relevant requirements; (8) sudden cooling water temperature is too high, or the sudden interruption; (9) main bearing cooling water leaks water into the oil surface and lubricating oils; (10) to start other parts , moving parts such as bolts loose or damaged components, affect the safety of production; (11) when the size of gear counterparts loose bolts. (Two) Maintenance 1, maintenance and repair of ball mill maintenance and repair is extremely important, and is a regular job, should the operation and maintenance with the ball closely together for. Mill maintenance work directly affects the mill operating rates and service life, therefore, should have full-time staff on duty checks. So that timely troubleshooting, ensure normal production. (1) main bearing, roller bearing, reducer, motor bearings injected oil (wax) must be clean, oil loading machine must be well sealed to keep the oil clean. Fuel oil level indicator shall comply with all requirements of lubricants are added regularly and replace as required. (2) on the newly installed or replaced friction and lubrication fittings, lubrication for 30 days after all the oil poured out another one in oil. Lubricating oil must be clean and free of contaminants to ensure, in line with the grades used (lubricants in Table 2) and scrub the oil sump. (3) winter fuel or oil change, the oil should be pre-heated to about 20 ? have been spoiled or prohibit the use of dirty oil. (4) Always check the bearing temperature does not exceed 60 ?, check the oil level lubrication points and lube oil pressure and fuel supply system, main bearing temperature Ball Mill should be controlled between 15 ? -60 ?. If the main bearings should be below 15 ? cooling water to reduce or temporarily closed. (5) of the newly installed liner bolts, a few days at the beginning of operation often prone to loosening, therefore need to regularly check and tighten bolts and should be careful to check the liner loose and broken. (6) Make sure to check and record the current value of the motor changes, if current decreases, indicating the grinding mill liners such as excessive wear and tear and should be replaced promptly adjusted. (7) In addition to routine maintenance, but to regularly check the main bearing, hollow shaft, cylinder, reducer, small gears, linings for wear and make a record, identify problems and timely treatment, good maintenance plan. 2 Notes (1) In the winter, if the stop grinding long time, it should be installed in the outlet of the main bearings had to turn on the water at the three-way cock position, using the siphon effect, the spherical bush string waterway water exclusion, avoid cracking spherical bush or bearing. (2) stopping every 5-10 minutes after grinding, the grinding half turn, stops opposite the original position until sufficiently cooled until the grinding body, to prevent the deformation of the mill body. (3) a sudden power failure during operation, and ancillary equipment shall mill motor power supply is disconnected, so call accidents. (4) Long-term stop grinding, should be poured out of the ball, in order to avoid deformation and bending cylinder. (5) produced in the winter end mill waste to the attention of insulation work, if less than the dew point, there will be cooling water, damage to the dust collector. (6) Winter (North) stop grinding more than 8 hours in a moving machine should start releasing the main bearing oil heated to 20 ? and then poured into the bearing. (Three) overhaul ball mill during operation, will produce some wear parts or components, if unscheduled maintenance will affect the normal operation of equipment, even equipment accidents occur. To ensure the timely recovery of each part of the original action, the use of units must be adjusted according to the equipment wear, cleaning and replacement of restoration and partial replacement. 1, the transmission device (1) for the motor the motor specification requirements for maintenance. (2) gear reducer overhaul specification requirements shall be carried out. (3) the size of the gear tooth thickness worn to account for 25% of the original tooth thickness, or break off the teeth should be replaced and repaired. (4) Drive Shaft 10mm deep cracks appear to be repaired or replaced. (5) Ball Mill flexible pin coupling studs break due to overloading should be replaced. (6) The rubber block rubber block coupling being crushed, or severely worn should be replaced. (7) Rolling bad seal oil leaks, excessive bearing wear, radial clearance greater than 0.3 mm, should be restored or replaced. (8) in the scraper unit gear cover wear or can not afford oil scraping effect, should be restored and replaced. (9) gear cover sealing device should ensure a good, if not a good seal or leakage should be timely adjustment and replacement. 2, the main bearing (1) spherical watts babbitt be crushed or worn 5 mm, to be re-cast babbitt. (2) the main bearing surface wear appear to be drawing more than 1 mm depth repair, hollow shaft cracks should be repaired and replaced. (3) scraping oil cooler with oil scraper ring with oil bad situation should be promptly repaired and replaced. (4) main bearing seal should be good. If found leaking seals should be checked for wear, such as wear and tear should be replaced with the adjustments, such as brush scraper scraper plate mounting angle is wrong, should be timely adjusted the brush scraper scraper plate mounting angle and position and direction of rotation for wear. (5) main bearing spherical watts or mixed with oil leaks and repair should be replaced. 3, the rotary part (a) out of the feed screw barrel and blades worn or frayed to the original 70% to be repaired or replaced. (2) grate plate, diaphragm plate wear more than 50% of the original thickness should be replaced. (3) grinding liner, liner broken off edges, cracks or wear off angle exceeds 70% of the original thickness should be replaced. (4) the thickness of the cylinder wear to the original thickness of 20% or cracks, local deformation, should be repaired and replaced. (5) Manhole Cover and seal is damaged, it should be replaced. (6) ball forging wear, should be regularly clearance sorting, replenish, but are prohibited from the feed screw barrel plus ball into the mill, in order to prevent abrasion feed screw barrel. (7) liner bolt wear, loosening liner shall replace bolts. 4, into the feed section (1) feed hopper wear, or replace worn to welding. (2) feed hopper and feed screw and barrel wear the seal between the drain material or ash leakage should be repaired and replaced. 5, the material part of (a) theBall Mill material to cover gray seal failure leakage, should be timely repair and replacement. (2) excessive wear discharging sieve, sieve or blockage should be worn between welding, repair, cleaning, replacement. (3) the material to cover ground to 1 mm or worn when welding or replacement.
