The unit is manufactured by Coperion K-Tron, and is a scale hopper that has an utmost operating capacity that ranges from 7 cu. ft. up to 104 cu.ft. The inlet of the unit has a tangential entry baffle, thus offers an improved material-air separation function, and fills the hopper even more. The hopper is steep, and is sloped at 63° that improves its functionality in discharging hard-to-handle objects.
