16.1 During operation, the ball mill hollow bearing bush, oil circuit system, gears, motors and lubrication parts, classifier shaft head return sand ditch, etc., check every half hour, require good lubrication, stable oil pressure, normal oil return, each motor The temperature shall not exceed 60 °C, and there shall be no oil leakage at each lubrication point. The bearing temperature of each part must not exceed 60 °C.
16.2 Ball mill end cover, cylinder screw, transmission screw, drive shaft and its coupling part, classifier, etc., check every hour, require screw fastening, good sealing, no leakage or leakage.
16.3 If an abnormality is found during the inspection, it is necessary to find out the cause in time, and the post personnel shall handle it. If it cannot be handled at one time, it shall promptly report to the class, the team leader or the factory shift schedule, and strengthen the inspection and maintenance of the hidden danger parts to prevent accidents. Fill in the operation record carefully.
16.4 When the front and back of the ball mill exceeds the specified temperature, it shall not stop immediately. It must be injected into the bearing bush with new oil. After the temperature drops to the specified temperature, it can be stopped for inspection.
16.5 If the oil pressure is found to increase, the cause should be ascertained. If the oil pipe is blocked, stop it.
16.6 Regular inspection and maintenance:
sequence number | Check dimension Protection part | Check maintenance content | Maintenance standard | cycle | Be responsible for Work type |
1 | Various parts of the body | 1. Each part of the screw fastening degree 2. Size gear wear 3. Hollow bearing bush wear and contact surface cleaning oil groove | 1. Firm and reliable, moderately tight 2. According to the standard specified by the gear and clean the oil 3. Alloy scraping tile standard cleaning pad or oil groove | Every shift February to April 12 months | Operator fitter fitter |
2 | Lubrication system | 1. Lubrication pump pipes, valves. Filter | 1. The normal working line is unblocked | 6 months | fitter |
3 | Feeder | 1. Wear condition, fixing screw and scoop | 1. Welding repair or replacement and fastening | per month | fitter |
4 | Transmission section | Coupling unit 2. Reducer gear bearing wear and clearance 3. Belt, pulley | 1. Adjust the axis to make the deflection reach the specified standard 2. Replace the rubber mat and the Xiao nail according to the standard of the reducer, no leakage 3. Adjustment, replacement, and fastening | 6 months 6 months 1 month | fitter fitter fitter |
5 | Electrical part | Motor temperature rise 2. Motor bearing 3. Short circuit slip ring and oil switch 4. All high and low voltage electrical appliances | 1. Not more than 60 ° C 2. The gap is appropriate 3. Sensitive and reliable 4. Cleaning is sensitive and reliable | Every shift 1 year 30 to 45 days 6 months | Operator Electric fitter electrician electrician |
16.7 Cleaning per shift (responsible for the operator).
Serial number | Cleaning site | Work content |
1 | Lubrication system | External cleaning of all lubrication systems after parking |
2 | Transmission section | 1. Shaft and bearing, gearbox housing, counter wheel and pulley, etc. 2. If the belt is driven, it is strictly forbidden to drop the oil onto the belt. If there is oil, it should be wiped clean to avoid erosion (must be treated in the parking) |
3 | Electrical parts | Wipe the electrical equipment and the dust outside the motor |
4 | Other departments | 1. When cleaning, the lubricating oil flowing out should be cleaned up in time and must not flow to the cement foundation. 2. Waste oil rags should be placed in designated places 3. Keep the equipment clean around |
16.8 Lubrication regulations are as follows:
Serial number | Lubricating part | Type of lubricant | cycle | Come on principal | ||
Come on | Change oil | |||||
1 | Size gear | Graphite grease viscosity Ð100=4～4.5 | Every shift 2 times | 6 months | Operator | |
2 | Hollow bearing | 50 # mechanical oil viscosity Ð50=5.24～7.07 | Every shift | 3 months | Operator | |
3 | Pinion bearing | slide | 50 # mechanical oil viscosity Ð50=5.24～7.07 | Every shift | 3 months | Operator |
scroll | Calcium-sodium grease drop point T=90°C | Every shift | 6 months | Operator | ||
4 | Reducer gears and bearings | 45 # machine oil viscosity Ð50=5.24～7.07 | Every shift | 3 months | Operator | |
5 | Electric motor | Calcium-sodium grease drop point T=120°C | 6 months | Electric fitter | ||
16.9 The oil pressure of the oil should be between 0.7 and 1.4 kg/cm 2 .
16.10 All lubricating pipeline joints and bearings shall not be allowed to leak oil. The fuel tank, bearings, bearing caps, etc. shall be well sealed and dust intrusion shall be strictly prohibited.
