Device for feeding and metering of powderized or granulated goods contained in a hopper

摘要

The device has a drive unit (11) to produce an alternative transfer unit with an oscillating mechanism (16). The mechanism is actuated with a straight and dissymmetric to-and-fro movement with a horizontal stroke adjustable from 0.5 millimeter to 20 millimeter and an oscillation frequency comprised between 5 and 100 hertz. A guide and transfer chute (12) transports powder or granular material placed above a storage hopper.
