Screw conveyor is a kind of material conveying equipment used to convey materials from the feed port to the discharge port. The thrust generated by the rotation of the spiral blades is used to convey the solid materials.
Screw conveyor is mainly suitable for conveying powdery, small, and non-wettable materials, such as cement, lime, mineral powder, bricks and tiles, fertilizers, corn and other granular or powdery materials.
Maintenance and overhaul requirements of double-axis screw conveyor
Daily regular overhaul is an important guarantee to ensure the long-term and stable operation of double-axis screw conveyor.
- Check the motor and other external components to ensure that they function properly. Check whether fasteners such as bolts and nuts are loose, and whether the screws of the spiral connecting shaft are firm to prevent malfunctions caused by looseness.
- Remove dust and debris inside and outside the screw conveyor, keep the spiral blades and the box clean, and prevent corrosion caused by accumulated materials;
- Regularly check whether the spiral blades are worn, and repair or replace the damaged spiral blades if serious;
- Regularly check whether the bearings and sealing devices are in good condition. The bearings need to be regularly filled with lubricating oil to ensure that the grease is sufficient and not deteriorated.
- Bearing wear or seal ring damage needs to be handled in time to ensure normal sealing performance.
- Check the support bearings and replace them in time if bearing wear is found.
- Check the transmission device regularly, including the tightness of the transmission chain (transmission belt), the clearance of the gear meshing, etc., which need to be adjusted to the appropriate range to ensure that the transmission device can operate safely and reliably.
Note: During the operation of the screw conveyor equipment, the cover, guardrail, etc. must be kept closed and must not be opened。
Conclusion
The screw conveyor is an economical and reliable general material conveying device with a simple structure, strong conveying capacity, and stable use effect. It is widely used in coal, petrochemical, metallurgy, building materials, food, light industry and other industries. During the use of the equipment, daily inspection and regular maintenance are required, and problems must be handled in time.Read More: screw conveyor wikipedia
