The BPS Model BBD-4K is a large capacity bin vibrating unloader discharger. This reliable and robust unit is used to unload large capacity bulk bags that may need additional force to discharge the material. The BBD-4K uses heavy isolation mounts along with an 1800RPM vibratory motor to agitate the material inside the bag.

FAQ

Frequently Asked Questions

Can the BBD-4k handle bags larger than 4,000 lbs?

The standard design accommodates up to 4,000 lbs. For heavier capacities, consult the manufacturer about potential upgrades or a customized frame.

What if my material doesn’t flow easily?

Optional agitators, massage paddles, or vibration aids can help loosen compacted material. Adding a proper flow control valve also helps regulate discharge rates.

How can I minimize dust during unloading?

Use a sealed spout clamp, integrated dust hood, or connect the unloader to a dust collection system. Proper ventilation and filtration can further contain airborne particles.

Do I need a forklift or can I include a hoist system?

Either approach works. Many models include an overhead hoist assembly for facilities without forklift access. Choose the option that best fits your workflow and space constraints.
