Screw conveyors are versatile mechanical handling equipment used to transport bulk solids, powders, granules, and slurries. With a rotating helical screw blade inside a trough or tube, the conveyor moves material continuously along a precise path. Our screw conveyor systems are designed for reliable performance in industries such as agriculture, food processing, chemical production, mining, cement, building materials, and wastewater treatment. Every conveyor is manufactured with high-quality materials and advanced fabrication techniques to deliver long service life and consistent throughput. Our factory-direct pricing offers excellent value.

A standard screw conveyor consists of a motor, gear reducer, coupling, screw shaft, helical flighting, housing or trough, end plates, inlet and discharge spouts, and optional bearings. The motor drives the screw at a controlled speed. As the screw rotates, the flights push bulk material forward. The housing prevents spillage and keeps the conveyed material enclosed. Depending on the application, the screw element may be a shafted auger, a shaftless spiral, or a ribbon flight. We offer both tubular and U-trough designs. Tubular screw conveyors are fully enclosed for dust-proof operation and are suitable for fine powders; U-trough conveyors allow easier cleaning and inspection.

We provide a complete range of screw conveyors for different materials and installation conditions. Horizontal screw conveyors are ideal for moving dry bulk materials over short or medium distances. Inclined screw conveyors lift materials at angles up to 45 degrees or more with reduced efficiency. Vertical screw conveyors save floor space and elevate powders and granules to elevated hoppers. Shaftless screw conveyors are perfect for sticky, stringy, or high-moisture materials because the spiral has no shaft and can handle more material volume. Flexible screw conveyors use a special spring-like screw inside a flexible tube, allowing materials to follow bends and reach difficult locations. Our team can customize the length, diameter, motor power, screw pitch, and discharge position to match your process.

Material selection is critical for screw conveyor performance and service life. Our standard equipment is made of Q235 carbon steel with a durable powder coating. For food, medicine, or corrosive chemicals, we manufacture the screw, housing, and contact parts from stainless steel 304 or 316L. Optional surface treatments include electro-polishing, acid washing, and wear-resistant hard facing. All welds are performed by certified welders and inspected to ensure smooth, crack-free joints. We also provide custom hoppers, flanges, supports, and discharge valves to integrate with your existing process line. Each conveyor is test-run before shipment to confirm correct rotation, alignment, and sound level. This strict quality control ensures our screw conveyor performs reliably under demanding operating conditions.

Proper installation and operation are essential for maximizing screw conveyor service life. Before installation, check the foundation and support structure to ensure alignment and sufficient strength. Flange connections should be sealed to prevent dust leakage. During operation, monitor the motor current, bearing temperature, and vibration. Do not start the conveyor under full load unless it is designed with a soft starter or frequency converter. The inlet feed should be controlled to avoid choking or overloading. Lubricate bearings and gearbox according to the maintenance schedule. Inspect screw flighting, shafts, and troughs regularly for wear. Replace worn parts promptly to prevent jamming and unscheduled downtime. Always follow lockout/tagout procedures before cleaning or repair. With these safeguards, our screw conveyor delivers efficient, safe, and long-lasting material handling.
