Before starting the screening machine, check whether the main shaft of the shaker is flexible, whether the screening machine is lubricated, and whether the connecting parts such as bolts are loose. The screening machine with dust removal device should start the dust removal device first, and then start the screening machine. After normal operation, the screen surface of the drum screen can be evenly distributed.

2. During the operation of the roller projector, the staff should regularly check the wear of the equipment, check whether the local wear of the screen surface leads to leakage, whether the screen surface is too large or deformed due to the screen hole wear, which affects the accuracy of particle classification and fertilizer screening efficiency. If the screen is damaged, it must be stopped for repair. Parts and components of over worn screen should be replaced in time.

3. When the drum screen is running, the bearing of the filter should be lubricated correctly. In normal operation, grease should be injected once a week with an oil gun. Every two months or so, remove the bearing cover to clean the bearing and re insert the grease. At the same time, check the temperature of the bearing carefully. The bearing temperature shall not exceed 40 ° C and the maximum value shall not exceed 60 ° C.
