JOEST dual-mass resonance conveyors are used for transporting bulk material and general cargo over long conveying distances. An oscillatory system consisting of a trough and working springs with active vibration absorbers at regular intervals is energized at very low frequencies by an eccentric slider-crank drive unit.
The machine’s base frame is anchored to the foundation, and the system requires only very little drive power. Since the dynamic restoring forces of the working springs are largely compensated for by the active, mass-compensated system of vibration absorbers, only very low residual dynamic forces are transmitted into the foundation. With this system, large oscillation amplitudes are possible, enabling high flow rates. The maximum technically feasible length is about 70 meters. In these machines, the conveyor trough is bolted to a support frame and is interchangeable. The slider-crank drive contains standard housing bearings, a three-phase standard motor (foot type) and a V-belt drive. This machine is available in a curved design. This type of machine is often used as a sorting or breaking conveyor in the foundry industry. With vertical acceleration values below 1 g, the material does not lift off the trough during the conveying process (low-noise / gentle). Nevertheless, during conveying even heavy castings can be rotated or moved slightly on the trough, allowing ergonomic, energy-saving working over a prolonged period.
Dimensions and design features are tailored to the customer’s specific requirements.

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.
