Question 1

How fast can a big bag unloader empty FIBCs?

Accepted Answer

Many standard duties run about 6-12 bags per hour. Actual rate depends on bag weight (often 0.1-2 t), powder flowability, massage aids and how fast operators change bags.

Question 2

How is dust controlled at the spout?

Accepted Answer

A pneumatic spout clamp seals the FIBC outlet to the hopper. Local dust extraction or a pulse filter removes fines at the connection; light dust may only need a vent cartridge. Closed-cabin styles add further containment.

Question 3

What if the powder bridges or does not flow?

Accepted Answer

Pneumatic massage / beating paddles squeeze the bag to promote discharge. Hopper geometry, liners and vibrators can be added for sticky or hygroscopic powders after material review.

Question 4

Can the station feed a vacuum conveyor or weigher?

Accepted Answer

Yes. Buffer hoppers commonly discharge through a screw, rotary valve or vacuum pickup. Optional weigh hoppers release a set weight to downstream mixers or conveying.

Question 5

What information do you need to size the frame and hoist?

Accepted Answer

Bag dimensions and safe working load, material properties, required bags/h, available headroom, dust / ATEX zoning, preferred construction, and downstream equipment (mixer, silo, vacuum line, etc.).

Question 6

What maintenance is important on the hoist?

Accepted Answer

Operators should regularly check hoist condition, wire rope or chain, hooks and supports, keep the station clean, and lubricate moving parts per the manual. Stop use and service if any lifting component is damaged.
