The feeder is an airlock and is the heart of the feeder assembly, robust in construction, tight tolerances between the rotating rotor assembly and the housing keep air from escaping.
The feeder assembly consists of a rotary airlock, drive, tee-injector and support base. Metered material is directed into the top of the feeder, the feeder internal rotor assembly rotates and allows material to be deposited into the tee-injector below. The feeder size is based on material volume passing through the feeder. The internal helical rotor assembly is constructed of thick steel blades, the ends of the blades have stainless steel overlay tips. The feeder internal housing is machined and chromed to extend the life of the feeder. A chipper quality knife is located at the top on one side and allows for shearing by the helical rotor blades.
A tee-injector is mounted directly below the feeder and allows material to fall from the feeder into an airstream created by the blower assembly. A base supports the feeder and the tee-injector, the centerline of the tee injector is typically 12” off the ground.
