Automatic Metering Screw Feed System for Mixing and Dispensing Dry Powders into a Secondary Process
Designed as a direct replacement for Wallace & Tiernan 32-055 volumetric feeders, the new Scaletron VMF-90WT Volumetric Screw Feeder is a fully-featured, automatic feeding system capable of accurately dispensing many common chemicals found in the water and waste water industries, as well as, a host of other industrial chemicals. The VMF-90WT is the perfect choice for for seamless integration with an existing system using a Wallace & Tiernan feeder. The complete system is comprised of a screw feeder, hopper with W&T adaptor, SCR motor control module, wetting cone with eductor or solution mixing tank with mixer and a base stand.
