Screw (Auger) Conveyor Systems

Steady & Reliable Manufacturer

Product Detailed Professional Description

Screw (Auger) Conveyor Systems are mechanical systems utilizing a rotating helical screw flight (the auger) contained within a fixed trough or tubular casing. Rotation of the screw pushes bulk material (powders, granules, flakes) along the length of the conveyor. They are designed for sealed, horizontal, inclined, or vertical transport of flowable, non-sticky bulk solids. Key design parameters include screw diameter, pitch, flight clearance, and material of construction, which determine the transport rate and handling capacity for specific bulk densities.

Introduction & Company Integration

Wuxi Huiqian supplies specialized, contained bulk material handling equipment designed for precision dosing and reliable transport. Our Screw Conveyor Systems are engineered with robust screws and sealed casings to prevent dust leakage and ensure product integrity. We utilize systematic sizing and engineering calculations (based on bulk density and flowability) to deliver continuous, reliable transfer solutions essential for chemical processing, food ingredient handling, and agricultural applications.

Application Fields

Chemical Processing: Dosing and transporting powdered chemicals, resins, or pigments under sealed conditions.
Food Ingredients: Moving flour, sugar, spices, or grain from storage silos to processing mixers.
Wastewater Treatment: Conveying dewatered sludge, screenings, or chemical flocculants.
Plastics Industry: Feeding plastic pellets or regrind from hoppers to extruders.

Specification

Conveying Medium	Solid or Sectional Helical Screw Flight
Housing Type	U-Trough (for access) or Tubular (for sealed transport)
Screw Diameter	100 mm to 600 mm (Dependent on capacity)
Material Flow Rate	1 to 300 cubic meters per hour (Varies by size and speed)
Angle of Inclination	Up to 90∘ (Vertical, using special design)

Material Selection Guide

Materials must resist abrasion and corrosion specific to the bulk solid:

Screw Flights: Carbon Steel (general industrial duty). AISI 304/316 Stainless Steel (food, chemical, corrosive service). Abrasion-resistant coatings (e.g., Hardox) for extremely abrasive solids.
Trough/Tube: Heavy-gauge Carbon Steel or 304/316 Stainless Steel, often specified with high-density polymer or hardened steel liners for wear protection.
Bearings: External-mounted, sealed bearings (or hanger bearings inside the trough) appropriate for dusty or corrosive environments.

Services

Advantages & Core Features

Contained Transport: The fully enclosed design prevents material loss, dust emission, and protects the material from environmental contamination.
Versatile Routing: Capable of transporting material horizontally, on inclines, or vertically, offering flexibility in plant layout.
Metering Capability: When run by a Variable Frequency Drive (VFD), the screw rotation speed directly correlates to the volumetric flow rate, allowing for high-accuracy material dosing.
Simple Maintenance: Features such as removable covers and access hatches simplify internal inspection and cleaning of the trough or tube.

FAQ

FAQ (Frequently Asked Questions)

Q: Why do some screws use a tubular housing and others a U-trough?
A: Tubular housing offers the highest degree of sealing and is often required for vertical or highly dusty transport. U-Troughs are used for easier access to the screw for cleaning or inspection, especially with sticky or abrasive materials.

Q: Are screw conveyors suitable for sticky or high-moisture materials?
A: Standard screws can be problematic with very sticky material due to potential bridging or material build-up. Specialized designs, such as variable pitch flights or shaftless augers, are used to improve conveyance and flow characteristics for these challenging materials.

Production & Customization Services

We focus on flow optimization and access features:

Custom Pitch and Taper: Manufacturing screws with variable pitch or tapered flights near the inlet to improve material pickup and prevent bridging.
Multiple Inlets/Outlets: Fabricating the casing with multiple bolted inlet hoppers and slide-gate discharge ports for flexible material distribution.
Shaftless Design: Producing specialized shaftless augers for handling sticky, stringy, or extremely challenging materials prone to wrapping around the central shaft.
