The trough screw conveyor is a versatile and robust mechanical system designed for the horizontal or inclined transport of bulk materials. Featuring a U-shaped trough and a rotating helical screw, it efficiently moves powders, granules, and semi-solid substances with precision and minimal spillage.
Whether handling grains, cement, or industrial waste, the trough screw conveyor delivers reliable, continuous material transfer with high efficiency. Its adaptability and cost-effectiveness make it a preferred choice for bulk material handling across multiple sectors.
For enhanced performance, options like variable speed drives, specialized flight designs, and corrosion-resistant coatings can be integrated. Choose a trough screw conveyor to optimize your material transport process with precision and durability.
● Total sealed structure, no pollution to the environment
● Conveyor length can be customized according to your need
● Simple structure,compact design,which saves a lot of space
● Multiple inlets and outlets can be customized as per requirement
● Can be disassembled into several sections to save space during transportation
● The conveyor can withstand material temperature up to 200 ℃
● Wide application range to satisfy various bulk material transportation demand
1) Reasonable loading method, including the requirements of feeding and discharging devices.
2) Conveyor mutual relations in transmission line. The start-up sequence is started from material receiving conveyor. Shut-down sequence is started from material feeding conveyor.
3) If above requirements of start-up & shut-down sequence can't be met, surge bin can be added between conveyors to improve adaptive capacity and operation rate of the system.
4) Environmental protection requirements. Sealing type conveying or necessary dust-cleaning apparatus should be used for large dust transportation.
5) The supply availability of the standardization & universalization of components and quick-wear parts.
Maintenance of Trough Screw Conveyor
Regular maintenance of a trough screw conveyor is essential to ensure efficient operation and prolong its service life. Key steps include:
Lubrication – Regularly grease bearings and moving parts to reduce friction and wear.
Inspection – Check for wear on the screw flights, trough lining, and seals, replacing damaged components promptly.
Cleaning – Remove material buildup to prevent blockages and corrosion, especially in abrasive or sticky applications.
Alignment Check – Ensure the screw and trough are properly aligned to avoid excessive vibration or motor strain.
Bolt Tightening – Secure all fasteners to maintain structural integrity and prevent leaks.
Motor & Drive Maintenance – Monitor belts, chains, or gear reducers for tension and wear, lubricating as needed.
Safety Checks – Verify guards and emergency stops are functional to protect operators.
Following a scheduled maintenance plan minimizes downtime and ensures reliable performance.
