Bulk Bag Dump Stations (BDS)

Bulk Bag Dump Station for 50 lb or 100 lb bags

BDS for 50 lb or 100 lb bags

For 50/100 Lb Small Bag Unloading
MODEL BDS

Loading the Unit:

The “BDS” Bag Dump Station provides a safe and ergonomic design for the batching operator. Loading of the BDS 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 push button station for starting the dust collection and/or the vibration of the shaker grate.

Rear door access to the bag unloading station

Rear Access Door:

Access to the bag area is via a hinged rear, dust-tight door. Optional features include a vibratory sifting screen below the BDS, as well as conveyors and feeders to meter or elevate product. Note the optional motor vibratory sieve unit below the bag dump area in the photo illustrations.
