MODEL BDS
BAG DUMP STATION

FOR 50/100 LB. SMALL BAG UNLOADING

LOADING THE UNIT

B.E.S.T.'s "BDS" Bag Dump Station provides a safe and ergonomic design for the batching operator. Loading of the BDS "Bag Dump Station" is simple and easy, in a totally dust-contained environment. 50 to 100 lb. bags are easily broken and unloaded. A screen deck on the support surface retains any paper, foreign products, or oversize lumps from entering the process system.

The cover is maintained in an up or loading position via a gas- filled cylinder. Bags are dropped onto a knife-like edge, to cut and split bag into two halves. The air vibrator, shaker grate, cleans the bags in the collector and returns all collected dust, back into the product flow hopper below. Controls include a NEMA 12 twin pushbutton station for starting the dust collection and/or the vibration of the shaker grate.
