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.

Dimensions and design features are tailored to the customer's specific requirements
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

Shakeouts are generally placed directly after the ball ejector of a green sand molding line. The separation of casting and molding sand is carried out by high-frequency vibrations of suitable parameters with high acceleration. The separation channel is provided with a case with a customized grid surface through which the used sand is discharged downwards.
