Home » Charging & Feeding » Hopper Discharge Feeder (unbalance channel)

Hopper discharge feeders are special discharge devices for a wide range of bulk materials from hoppers and silos.

Two self-synchronizing counter-rotating JÖST unbalance drives are attached to a channel-shaped machine body which they excite via a linear oscillating movement, which in turn conveys the bulk material by means of micro throwing movements and discharges it from the hopper. With this type of design, very high discharge rates can be achieved. 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.

Advantages

Hopper Discharge Feeder (unbalance channel)

High discharge rates are achievable

Not susceptible to blockages

Existing bridges in the bunker are eventually dissolved by vibration

Discharge mass flow is largely independent of the hopper filling level

Good adjustability of the mass flow via the layer thickness slider
