Screw conveyor is used for conveying powder, granular, general purpose small bulk materials conveying equipment, all kinds of bearings are in dust work, so reasonable operating and maintenance work under such conditions would have more screw conveyor great significance, screw conveyor operation and maintenance of the main requirements are as follows:

1. The screw conveyor should be no load start, that does not start at the shell material, after starting the beginning of the feed screw conveyor.

2. Screw Conveyor irregularities occur during operation should be checked, and eliminate it, can not be forced to operate.

3. In order to ensure the screw machine without load starting requirements, before stopping the conveyor should stop feeding, and other materials to make completely lost inside the casing rear was stopped.

4. screw conveyor cover while the machine is running should not be removed, so as to avoid accidents.

5. shall not be mixed within the material being conveyed bulk materials hard to avoid the death spiral card spiral machine damage.

6. The initial feed screw conveyor, the feed rate should be gradually increased until it reaches the rated transmission capacity, feeding should be uniform, or likely to cause delivery of materials product plug, the drive overload, so that the entire machine early damage.

7. Use the screw machine regularly review the work of each member state, pay attention to each fastener is loose, loose parts if found, should immediately tighten the screws, so that re-tighten.
