Volumetric Screw Feeders

Introduction

Thayer Volumetric Feeders

DPH Engineering manufactures durable and long-lasting Volumetric Screw Feeders specifically designed to feed difficult powders such as TiO2, talc and calcium carbonate, and to address the flooding and bridging problems posed by many other powders.

Our innovative and high-quality volumetric feeders offer:

A unique feeder trough that deaerates and confines powder at the initial fill cycle to prevent flooding
An independently-driven agitator that conditions the material and introduces it to the feed screw with a consistent density
Feeders that disassemble easily (tool-free) for thorough cleaning, eliminating contamination problems which often occur when changing materials
Heavy-gauge 304 stainless steel as a standard offering (316 stainless steel is also available)
Customized screw lengths and special designs to facilitate operation over a wide operating range with both heavy- and light-density materials
