Screw Conveyor
Product Highlights
Energy-efficient, stable, and reliable with adjustable flow rate. Fully enclosed to prevent dust, easy to disassemble and clean. Features intelligent start/stop control and low maintenance costs.
Application Scope
Widely used for continuous feeding and conveying of powders and granular materials in industries such as chemicals, food, pharmaceuticals, feed, building materials, and plastics.
Suitable Materials
Plastic pellets, flour, medicinal powder, feed, mineral powder, grains and cereals, various chemical powders, small granular raw materials, and other powdery or granular materials
How it works
Motor-driven spiral blades rotate to push material forward, ensuring uniform conveyance through the spiral thrust. Feed rate is precisely controlled by adjusting motor speed. The compact, fully enclosed design ensures smooth operation with low energy consumption and supports both inclined and vertical installation to adapt to site requirements.
Use Cases
Proven across multiple industries and material scenarios.
Food Industry
Frequently uses 304 stainless steel models for sealed conveying of powders and granular materials, preventing dust leakage and product contamination. Ideal for continuous feeding in food production lines and compatible with cleaning structures.
Healthcare Industry
Hygienic screw conveyor with seamless polished structure to prevent material residue and cross-contamination. Ideal for powder conveying in tablet and capsule production lines, meeting GMP cleanliness requirements.
Chemical Industry
Choose carbon steel or stainless steel models based on material properties for conveying dry chemical powders and granules. For sticky, bridging-prone materials, select variable-pitch configurations to enable sealed transport and minimize dust emissions.
Mining
Heavy-duty carbon steel spiral with wear-resistant blades for conveying dry slag and mineral powder; primarily used in short-distance transport for mineral processing, ideal for low-moisture ore powders.
Feed Industry
Universal spiral feeder for consistent, stable material feeding. Compatible with feed mixers and pelletizers; handles bulk raw materials in both granular and powder forms.
Building Materials Industry
Heavy-duty wear-resistant screw conveyor for transporting building material dry powders; commonly used in batching plants and putty production lines. Enclosed design suppresses dust generation.
Environmental Industry
Anti-stick screw conveyors are available for transporting desulfurization, denitrification, and solid waste treatment powders. Commonly used in garbage incineration and wastewater treatment chemical dosing systems.
