FUNCTION PRINCIPLE
The feed material passes through the hopper onto the conveying chute. This is made to vibrate at 50 (or 60) Hz by an electromagnetic charging vibrator. The volume flow can be infinitely adjusted. The layer height on the hopper can be adjusted in accordance with the product and need. The DR 100 can be driven externally via an interface; for example, the volume flow can be adjusted automatically to the grinding capacity of the Retsch ZM 200 Ultra Centrifugal Mill. The compact, no-maintenance design means that the vibratory feeders can be integrated simply into many devices or laboratory installations.
