Are You Acquainted with Inspection Standard of Ball Mill

The inspection content of ball mill includes: 1, after the repair: the main check the oil amount, adjust each clearance, fortified by bolt, the replacement of individual liner or liner wear examination, repair feeder; 2, minor repair: check cleaning measurement of tooth surface wear, check the liner wear, replace if necessary; 3, repair: change the incoming parts, replacement drive small gear wheel and bearing, reducer strip inspection. Big gear in run 3-5 years of use can be adjusted according to situation, hollow shaft run 3-5 years should be measured; 4, overhaul: disintegration inspection cleaning, measuring, according to the wear condition, repair or replace the big gear, hollow shaft, spherical, drive shaft and pinion and cylinder, is repaired change regulation of the electrical components, electrical equipment repair, commissioning acceptance work must be conducted. However, do you know the inspection standard of ball mill?

The inspection standard of ball mill is in the following:

1, two bearing base processing surface on the same horizontal plane, center distance tolerance of 1 mm, longitudinal centerline deviation 0.5 mm, not parallel axis deviation 0.5 mm per meter.

2, tile spherical uniform can contact Angle; Within every 50 x 50 was not less than 1-2 PM;Hollow shaft and tile interface should be 90 °, 100 ° per square inch of not less than 2 points, journal and bearing clearance approximately the same on both sides;

3, cylinder flange fitting surface shall ensure good contact with the front end cover, are not allowed to add gasket, two hollow shaft alignment tolerance is less than 0.8 mm. Big gear ring and cylinder end cover assembly correction, connectors should be strong thrust, superior dowel, ring gear radial swing is not greater than 0.5 mm, axial runout no greater than 0.84 mm;

4, lining board installation should be according to the loading end cover, cylinder liner should start with population, according to the requirements of...
