To power the Big Bag discharger, an electric hoist or forklift is used, this defines whether the equipment to be used will be with:

  • W-profile structure or;

  • Tubular profile rack.

The structure receives the integrated hoist and the rack is accompanied by its own adapter so as not to break or damage the big bag when lifting, allowing the rack to be fed through forklifts. After starting the unloading of the raw material at the hopper exit, there is a conveyor screw or rotary valve, correctly dosing the raw material to the pneumatic conveying line without danger of clogging.

The hopper can be presented in the following ways:

  • Closed for powder products;

  • Open for granulated products.

When closed, it can be equipped with a visor and glove box for handling the material inside the hopper for critical moments when unloading big bags. ​


The filter is used for powder products that can harm the environment, this is a determination of Brazilian legislation that refers to both work and environmental safety."
