High Capacity Stainless Steel Feeder: Flat Bottom (FB)

The new Coperion Flat Bottom (FB) is a high-capacity stainless steel feeder designed specifically for handling materials with light and fluffy characteristics. With a bottom-driven vertical agitator and an auxiliary agitator, the FB is perfect for hard-to-feed materials such as chopped polypropylene or PET plastic film when feeding to an extruder. The main agitator runs close to the flat bottom of the feed module to assist in the filling of the feed screw and the auxiliary agitator supports product flow at the lower end of the extension hopper. Having dual agitators makes it ideal for feeding lightweight materials in plastics processing applications.

The Coperion can be operated either as a loss in weight or volumetric feeder. When designed as a loss-in-weight feeder the unit comes equipped with VKN weighing modules that are either placed underneath the feet of the feeder or directly on the mounting floor. A modular hopper concept supports easy installation and a one-seal concept for all shaft seals provides quick maintenance.

The new FB is the perfect solution for feeding plastic flakes, cellulose, hemp, glass or carbon fibers, and other virgin or recycled materials for plastic film or compounding applications.
