Volumetric Dry Material Feeders

September 2, 2014

Schenck Process Tuf-Flex FeedersFor volumetric dry material feeding applications, the economical Tuf-Flex™ Series Feeders handle a wide variety of fine powders, flakes, granules, chips and pellets. Designed with a unique form of agitation the Series Feeders are manufactured with a Tuf-Flex™ vinyl hopper that is agitated on the exterior by two alternating paddles. The paddle action gently massages the material down into the metering screw, eliminating ratholing and bridging while conditioning material into a consistent bulk density. The helix flights are filled uniformly, resulting in excellent accuracy.

Offered in model sizes accommodating feed rates from .000017 to 280 cubic feet per hour, the Series Feeders can be found in various processing plants throughout the world.
