RFH Type Rubber Spring Feeders
High-capacity type for high-speed and large-volume
This Rubber Spring Feeders are vibrating feeders in which strong vibration generated by rotation of unbalanced weights is effectively combined with rubber springs. Due to the use of resonance vibration, high efficiency can be obtained and only a small amount of drive power is required.
As the feeding rate is easily adjusted during feeder operation and instant interruption of the flow of material is possible, this equipment also can be used as a weighing feeder.
Suspended
Base mounted
Operating Principle
The structure consists of a trough that carries the material, a drive unit that generates the vibration, and a resonant rubber spring that connects them. The elliptical vibration generated by the rotation of the unbalanced weight in the drive unit has the same effect as linear vibration on the material on the trough. Therefore, a large amount of powder, grain, or bulk material can be speedily cut out and fed.
Structural Diagram
Both suspension type and floor-mounted type are installable.
The trough and the drive unit are hold by suspension device (if you use a suspension type) or supporting device (if you use a floor mounted type).
