Barrel/Housing: Temperature Range -20°C to 200°C

Component Specifications

Definition

The barrel/housing in a metering screw/feeder is a cylindrical or rectangular structural component that forms the main body of the equipment. It houses the rotating screw, provides a controlled pathway for material transport, maintains pressure conditions, and protects internal mechanisms from contamination, wear, and environmental factors. It typically includes mounting interfaces, inspection ports, and connections for material inlet/outlet.

Working Principle

The barrel/housing creates a sealed or semi-sealed environment where the metering screw rotates to move materials at precise rates. It maintains geometric alignment, contains process pressure, prevents material leakage, and facilitates controlled feeding through its internal bore and discharge configuration.

Materials

Carbon steel (ASTM A36), stainless steel (304/316), hardened alloys, or wear-resistant liners (UHMW, ceramic). Material selection depends on application: food-grade stainless steel for sanitary requirements, carbon steel for general industry, or lined barrels for abrasive materials.

Frequently Asked Questions

What are the main functions of the barrel/housing in a metering screw feeder?

It contains the screw, guides material flow, maintains alignment, prevents contamination, and withstands operational pressures.

How do I select the right material for a feeder barrel?

Consider material compatibility (corrosion/abrasion), sanitary requirements (food/pharma), temperature, and regulatory standards.

Can barrel liners be replaced?

Yes, many designs allow replacement of wear-resistant liners to extend service life without replacing the entire housing.
