Auger Feed / Blend Control

Microprocessor-based control system for automated mixing and blending of plastic pellets from multiple hoppers

Overview

The Auger Feed/Blend Control is a microprocessor-based control system which provided for the mixing of three hoppers of plastic pellets.

The hopper had three motor-driven volumetric augers. The augers ran for a period of time, each at their own speed, as required to satisfy the volume of a large blend tank.

Once the hopper was full, the augers stopped and the blend motor was activated for a predetermined period of time to ensure thorough blending.

After blending, an air cylinder was activated to dump the contents into a supply hopper, from which product was taken automatically via a vacuum system to production.
