Four maintenance instructions for drying equipment: 1. Bearings are an important part of the dryer. The full load of the dryer is mainly borne by the bearings, so the lubricating oil directly affects the service life and operating rate of the dryer. 2. The lubricating oil of the drying equipment is clean and well sealed. The quality of the lubricating oil is crucial for the maintenance of the dryer. 3. The rotating bearings, root rolling bearings, gears, movable bearings, sliding surfaces, and newly installed wheel rims of the dryer are prone to loosening. Regular inspections should be conducted to ensure that all parts of the dryer are functioning properly and to check the degree of wear on easily worn parts. If necessary, worn parts should be replaced. 4. The dust removal work of the dryer should also be carried out daily to avoid interference from stains and dust, which may affect the smooth operation of the dryer.
