3 The Vibratory Feeder DR 100
Use the Retsch DR 100 feed units for uniform feeding and conveying of free-flowing bulk
materials and powders. Whether in direct connection with Retsch shredders or for simple
feeding of balances, mixing and stirring processes or measuring devices; the DR 100 is suitable
for flexible and effective applications.
The sample material enters the vibrating chute via the feed hopper. This is caused to vibrate at
50 or 60 Hz by an electromagnetic inline vibrator and to generate uniform material transport.
The vibration intensity and thus also the feed rate are infinitely adjustable.
The duration of the feed can be preselected and is digitally displayed. In standard operation, the
DR 100 is directly controlled by the downstream devices depending on the load.
Parts which come into contact with the sample material are all made of stainless steel.
Performance data:
•Uniform feed and conveying of free-flowing bulk materials with a particle size
of up to 12 mm or fine powders
•Digitally preselectable time operation from 1-99 min or continuous operation
•Stepless selection of vibration intensity
•Height adjustable hopper
•Parts which come into contact with the sample material made of stainless
steel
•Customization to external and standard operation in combination with Retsch
devices
NOTICE This laboratory instrument is designed for 8-hour single-shift operation at 30 % duty
cycle. This device must not be used as a production machine or in continuous operation.
