Key Features

Fully Enclosed Structure
Dust-tight design prevents material leakage and contamination.

Compact & Space-Saving
Ideal for installations with limited space or complex layouts.

Safe Operation
Enclosed system minimizes operator exposure to moving parts and materials.

Product Types

Horizontal Screw Conveyor
Designed for continuous horizontal conveying of bulk materials with stable and uniform flow. It is the most commonly used configuration for production lines and general material
transfer.

Inclined Screw Conveyor
Used to transport materials at an angle, combining conveying and lifting functions. Ideal for feeding systems and applications where elevation change is required.

Vertical Screw Conveyor
Engineered for vertical lifting in compact spaces. Suitable for handling powders, granules,and bulk materials in silo feeding and processing systems.

FAQ

Q: What types of bulk materials are your screw conveyors best suited for, and how do you prevent clogging or bridging?

A: Our screw conveyors are engineered to efficiently handle powders, grains, granules, and small pellets (such as flour, plastics, cement, and chemical powders). For cohesive, sticky, or hygroscopic materials that tend to compact or bridge in the hopper, we offer specialized engineering solutions. These include variable-pitch screws, ribbon flights, and integrated hopper vibrators or mechanical agitators to ensure a continuous, clog-free material flow.

Q: Are your screw conveyors compliant with food-grade sanitary standards, and how easily can they be cleaned?

A: Yes. For food, dairy, and pharmaceutical applications, we manufacture systems using high-grade polished Stainless Steel (#304/#316L). Our designs strictly comply with FDA and EU food safety regulations. To minimize maintenance downtime, we can equip the conveyors with quick-release split tube clamps, drop-bottom troughs, or bolted inspection hatches, allowing your operators to thoroughly wash down and sanitize the internal screw mechanism without complex disassembly.

Q: Can your engineering team integrate the screw conveyor into our existing production line, blender, or silo system?

A: Absolutely. We specialize in fully custom engineering. We provide comprehensive 2D layout drawings and 3D CAD models (STEP/IGES formats) within 24–48 hours for your technical team to verify space constraints, inlet/outlet alignments, and custom incline angles (standard 45°, or custom 30°/60°/vertical). Complete installation manuals, electrical schematics, and CE compliance certificates are always provided upon delivery.
