Hopper discharge feeders are special discharge channels for a wide range of bulk materials from hoppers and silos. A JÖST magnetic drive, designed as a sub-resonant dual-mass system, is attached to a channel-shaped machine body which it excites via a linear oscillating movement, which in turn conveys the bulk material by means of micro throw movements and discharges it from the hopper. In this design, the discharge rate can be widely varied, since the amplitude of the magnetic drive is adjustable via the built-in thyristor. Furthermore, the conveyor stops immediately when switched off without running on. Magnetic feeders are therefore especially useful for dosing (weighed feeding). Various parameters have to be considered in the system’s design and configuration, such as hopper pressure, hopper geometry, particle size, flowability, humidity, tendency to caking, etc. Hopper discharge feeders are therefore designed individually for each application.
