Vibrating Trough Type & Tube-Type Feeder

Vibrating feeders especially suit this conveying task as beyond

the simple design without any maintenance-intensive parts an extensive low-wear conveyance procedure (micro throw) of the product is permitted. The design and the choice of the conveying system is mainly determined by the feeding capacity to be required, the conveying length to be realized and certainly the efficiency.

For this JOEST offers an Vibrating Feeder (type FUF), executed with 2 unbalance drives which are fixed at the vibration saddle. The execution of the saddle varies when the conveying length increases. With regard to the frequently limited installation heights beneath the centrifuge station – lengths of up to 7,5 m each feeder have proven to be reasonable. A combination of several feeders offers the possibility to overcome larger lengths. In this case the increasing number of feeders and drives as well as the different interfaces has to be considered.

In addition to vibratory feeders with unbalance drive, JOEST also offers feeders with JOEST magnetic drives (type FMF) in its extensive product portfolio. With this design, the discharge capacity can be varied over a very wide range, since the vibration amplitude of the magnetic drive can be continuously adjusted with the thyristor controller. Furthermore, this design has the property that the conveying process stops almost immediately and without overrun after the conveyor is switched off. Magnetic chutes are therefore particularly suitable for metering purposes (scale feeding). Conveying lengths of up to approx. 4.5 m can be realized with a magnetic drive.

Vibrating tube-type feeders can be easily adapted to the required conditions for different industries. Both round and rectangular tubes can be used for both types of drive. Particularly ATEX and hygiene requirements can be well met by the closed design. Diameters between 89 mm and approx. 800 mm can be realized for round tubes.
