Screw Conveyor - Key Information

A Reliable Seamless Conveying Solution for Bulk Materials

Screw conveyors (also known as auger conveyors) are reliable solutions for transporting bulk materials (powders, pastes, granules). Widely used in wastewater treatment, chemical, food production, and construction industries, they effectively solve problems such as dust leakage, material blockage, and operation in narrow spaces. They support horizontal, vertical, or inclined conveying.

Core Advantages

Enclosed Design

Fully enclosed trough prevents dust leakage; sealed end caps avoid contamination; optional UHMWPE lining reduces adhesion, meeting food/pharmaceutical standards.

Flexible Configuration

Supports 0° (horizontal) to 90° (vertical) conveying; customizable trough length (2-30m) and diameter (150-800mm); modular structure for easy assembly/expansion.

Durable Construction

Trough options include carbon steel, 304/316 stainless steel, and manganese steel; screw blades made of 50-55 HRC hardened steel; sealed self-lubricating bearings reduce maintenance.

Precise Control

0.75-45kW frequency converter adjusts speed (0.5-50 RPM); capacity range 5-250 m³/h; optional blockage sensor prevents malfunctions.

Main Specifications

  • Models: SC-150 (small) to SC-600 (large)
  • Trough Diameter: 150mm, 200mm, 300mm, 400mm, 600mm (optional 700mm, 800mm heavy-duty models)
  • Conveying Length: 2m-20m (optional 20m-30m with intermediate support)
  • Conveying Angle: 0° (horizontal) -45° (inclined) (optional up to 90° vertical with special screw design)
  • Capacity: 5-200 m³/h (optional up to 250 m³/h high-capacity screws)
  • Materials: Trough: carbon steel, 304 stainless steel; Screw: hardened steel (optional 316 stainless steel, manganese steel trough; 304/316 stainless steel screw)
  • Motor & Protection: Power: 0.75kW-22kW; Protection class: IP54 (motor), IP65 (panel) (optional 30kW-45kW power; IP67 protection class)
  • Additional Components: UHMWPE lining, blockage sensor, inspection holes (optional load cells, heating jackets)

Industry Application Cases

Food & Beverage

A French bakery uses 2 SC-300 conveyors (304 stainless steel) to transport flour, reducing flour waste from 5% to 0.3% and achieving full automation.

Construction

A Chinese concrete plant deployed 3 SC-600 conveyors (manganese steel) to transport sand, operating 24/7 with 60% reduction in trough wear.

Wastewater Treatment

A Canadian plant uses a 35° inclined SC-400 conveyor to handle sludge, reducing blockages to zero and lowering disposal costs by 20%.

Equipment Integration & Cooperation

Screw conveyors can be seamlessly integrated with bucket elevators, dual-hopper packaging scales, and silos to build a complete "conveying-lifting-storage-packaging" workflow.
