Feeding, Micro-feeding & Metering

Rotary Feeders (Rotary Valves), Macro- and Micro-Batch Feeders, and Loss-in-Weight Feeders have been key to WAMGROUP’s success for decades, forming an integral part of its product portfolio and offering reliable, precise feeding solutions for a wide range of applications.

Drop-Through Rotary Valves

WAMGROUP’s Drop-Through Rotary Valves or Rotary Feeders are designed for controlled discharge and feeding of powders and granular materials from hoppers, silos and conveying systems. The range provides continuous material flow while maintaining pressure differentials between connected equipment. Available in different sizes and configurations, the valves can be supplied with various rotor, seal and drive options to suit specific materials and operating conditions.

Macro and Micro-Screw Feeders

WAMGROUP’s Macro- and Micro-Screw Feeders are designed for controlled, accurate feeding and metering of powders and granular materials. The range includes equipment for both high-capacity discharge and precise dosing of smaller quantities. Different screw configurations, sizes and drive options allow adaptation to material characteristics and required feed rates. The feeders can be integrated into weighing, batching and process systems across a wide range of industrial applications.

Double Dump Valves

WAMGROUP’s Double Dump Valves are designed for the controlled discharge of high-temperature bulk solids and materials with particularly large particle sizes, while maintaining pressure separation between process areas. Their two-flap configuration enables controlled batch discharge and helps limit air leakage during operation. Available in different sizes and configurations, the valves can be supplied with various materials and actuation systems to meet diverse industrial requirements.
