Flexible Screw Conveyors
Simple. Reliable. Cost‑Effective Powder Handling.
One moving part, dust‑tight conveying, and compact layouts that go where rigid conveyors can’t. Move powders, granules, and small pellets—horizontally, vertically, or on the incline.
Why Flexible Screw Conveyors?
- One moving part → low maintenance and high reliability.
- Dust‑tight operation with sealed inlets, tubes, and discharges.
- Versatile routing—run horizontal, vertical, or around obstacles.
- Blend integrity for many mixtures; gentle on friable products.
- Low total cost—economical install, simple operation, easy cleaning.
Design Features
Shown: typical features available on industrial and sanitary flexible screw conveyors. Your configuration may vary by application.
Configurations & Options
Compact Layouts with Custom Hoppers
Standard 45° incline or horizontal runs; curved routing to bypass obstructions; stainless or carbon construction; low‑level sensor and safety grate options.
Tool‑Free Disassembly & Hygienic Design
Rounded corners, smooth contact surfaces, washdown‑rated drives and controls, removable tubes/spirals, and drip/drain management for fast changeovers.
Easy Access to Spiral & Tube
Tilt feature pivots the conveyor to a horizontal position for cleaning or maintenance. Pair with quick‑release clamps for tool‑less disassembly.
From Bag Dumps & Bulk Bags
Integrate with bag‑dump stations, bulk‑bag unloaders, and feeders. Multiple discharges and transitions available to suit your process.
Common options: portable base frames, multiple outlets, flexible or rigid discharge chutes, level sensors, VFD speed control, clean‑out caps, inspection windows, and custom hoppers.
Capacities & Sizes
Throughput depends on product characteristics (bulk density, cohesiveness), auger size/pitch, tube diameter, and incline. We recommend testing to confirm rates.
| Common Tube Sizes | Typical Materials | Indicative Rates* | Notes |
|---|---|---|---|
| 3" (≈76 mm) | Powders, fine granules | Up to ~6 ft³/min | Great for flour, starch, sugar, protein powders |
| 5" (≈127 mm) | Granules, pellets, higher rates | Application‑dependent | Use for larger particles or higher throughput |
*Actual performance varies; we’ll size auger pitch/diameter and drive speed for your material and elevation.
Applications
Ideal for food (flour, sugar, spices, starch, coffee, protein powders), chemicals (additives, pigments), and plastics (pellets, regrind). Flexible screws also shine for compact bag‑dump to mixer transfers or bulk‑bag discharge to process.

FAQ
Will a flexible screw damage my product or separate blends?
Most powders and granules convey gently with minimal attrition. Many blends maintain integrity. We’ll review your material and, if needed, run a test.
Do I need a dust collector at the discharge?
Not typically; the conveyor is dust‑tight when properly sealed. Your receiving vessel may still need venting depending on process conditions.
How do I clean between products?
Choose easy‑clean features: quick‑release clamps, clean‑out caps, removable tubes/spiral, and tilt‑down access. For sanitary builds, add washdown‑rated components.
Can it run at any angle?
Yes—horizontal, vertical, and incline. Capacity changes with angle and product; we’ll size auger pitch/diameter and speed to suit.
