If you have not ever heard of it, today our expert of HXJQ will talk something about it. I think you can read this article with your a little time.

The maintenance work of coal mill is in the following: 1. guide Check the guide block and guide plate gap, when the gap is more than 8 mm, padded transferred to the required value. Check the abrasion of guide block. Check cycle: 2000 hours at a time. Abrasion of the surface of the guide block, will be able to adjust the clearance or adjusted anything run time, replace the new guide plate.6 hinged deviceCheck the hinge axis, hinge axis wear or plastic deformation. Testing time: during overhaulingIf wear, deformation, change a new one.

2. casing wear armor check casing wear abrasion of guard board. Check cycle: 2000 hours at a time. Wear and tear and wear guard was more than the original thick 1/2, shall be replaced. 8Roller shelf wear armor check wear armor plate, the abrasion of wear armor plate fastening screws, screw fastening wear guard.Check cycle: 2000 hours at a time. Wear plate and wear more than 1/2 of the original thickness When to replace. Roller oil levelCheck the oil seal and plug in oil.Open the lid on the roller support, measure the oil level, the oil level should be above the minimum oil level, the highest oil level, or must fill oil or oil. Check measuring time: 1000 ~ 2000 hours at a time (with a simultaneous assay for oil).

3. roll ring and linerMeasuring roller cover, liner wear and make records.Check cycle: 1000 hours at a time detect the abrasion of roller shell and lining board, according to wear flip or replacement.11 roller oil seal Oil seal check in roller disintegration. 8000 ~ 20000 hours, the service life of the oil seal of coal mill (http://www.crushing-mill.com/coal-mill/) is determined by the usage and maintenance cycle, when there is a skeleton deformation, lip wear, replace the new oil seal lip cut.12 rubber o-ring check in roller disintegration. Generally the service life of 8000 ~ 20000 hours, change is determined by the usage and maintenance cycle.
