Feeder Screw (Auger): Capacity 0.1-100 m³/h, Diameter 25-300 mm

Component Specifications

Definition

A feeder screw, also known as an auger, is a precision-engineered helical component that rotates within a tube or trough to transport powdered, granular, or pelletized materials from a storage hopper to a controlled discharge point. It ensures consistent material flow, prevents bridging or clogging, and maintains precise feed rates in automated industrial processes.

Working Principle

The feeder screw operates on the Archimedes' screw principle: as the helical flight rotates, material is trapped between the flights and the housing, moving axially along the screw's length from the inlet to the outlet. The pitch, diameter, and rotation speed determine the volumetric feed rate and material displacement.

Materials

Typically made from carbon steel, or AISI 304/316 stainless steel where corrosion resistance is needed, hardened steel for abrasion resistance, or food-grade plastics (e.g., UHMW-PE, acetal) for sanitary applications. Coatings like Teflon or chrome plating may be applied for specific material compatibility.

Frequently Asked Questions

What is the difference between a feeder screw and a regular auger?

A feeder screw is specifically designed for controlled, metered discharge in feeding systems, often with variable speed drives, while a general auger may be used for simple conveying without precise rate control.

How do I select the right feeder screw material?

Choose based on material properties: stainless steel for corrosive or food-grade applications, hardened steel for abrasive materials, and plastics for lightweight or non-contaminating needs.
