What regardless of the maintenance detection ball mill?

　　Ball mill is a very important part of the mineral process. This is very important for the maintenance of the ball mill. So what should you do to check the ball mill? First, Maintenance Cycle: After 1 month; small repair 1 to 3 months; medium repair 12 to 24 months; large repair 60 to 120 months. Second, maintenance content: 1. Repair: Mainly check the amount of oil, adjust the gap of each part, strengthen the bolts of each part, replace a single liner or check the wear of the lining, and repair the feeder. 2, small repair: Check the wear and measurement of the wear of the tooth surface, check the wear situation in the lining, and replace it if necessary. 3. Mid-repair: Replace the feeder, replace the transmission pinion and bearings, and disassemble the gearbox. Large gears can be adjusted according to the situation after 3 to 5 years. The hollow shaft should be measured after 3 to 5 years. 4. Dacao: Removing check, measure, repair or replace large gears, hollow shafts, spherical bricks, drive shafts, pinions, and cylinders, according to wear, repair and replace electrical components, after electrical equipment overhaul, test, accept Work. Third, the maintenance standard: 1. The machining surface on the two bearing hoses is 1 mm on the same horizontal plane. The non-parallel deviation of the longitudinal line is 0.5 mm / m. 2, the spherical contact surface of the tile holder should be uniform; each 50 × 50mm2 is not less than 1 to 2 points; the contact surface of the hollow shaft and the tile should be 90 ° ~ 100 ° per square inch is not less than 2 points, the journal The gap on both sides of the bearing is substantially the same. 3. The mating surface of the cylinder flange and the front end cap should ensure good contact. A gasket is not allowed. The two hollow shafts have a tolerance less than 0.8 mm. When the end cap of the large ring gear and the cylinder is assembled and corrected, the push pin should be firmly pushed and placed in place. The radial swings of the ring gear is not more than 0.5 mm, and the axial swing is not more than 0.84 mm. 4. When the ball mill is installed, the end cap should be installed first. The liner of the cylinder should start from the population and in accordance with the assembly requirements. The screw should be uniformly tightened and water is not allowed. The rubber lining should have no gap and should have a sponge to block the gap. 5. The pinion line is parallel to the line of the large gear, and the deviation is not greater than 0.2 mm per meter. The top gap is 1/4 modulus, and the side gap is 1.06 to 1.8 mm, and the tooth surface contact area is not less than 50 tooth long, and the teeth are 40. 6. Reducer, electricityThe drive coupling of the machine and the drive shaft should maintain a high coaxial degree. The axial direction of the line is different, no more than 0.3mm, and the wire angle is less than 1/1000. As long as you pay attention to the above three points, it is easy to improve the performance of the ball mill, improve the fineness of grinding, and prepare for the next flotation.
