Sack tipping station STB

Our task is to make all types of processes related to the processing of bulk materials simple and trouble-free. During the seemingly simple task of emptying small bags, the problem of dust formation is a common phenomenon. The STB stations we produce are a convenient solution to this problem.

The device is intended for solids delivered in sacks with a capacity of up to 50 liters. They provide a convenient way to empty and feed small amounts of product into the main process – e.g. a mixer or transport system between two distant points in the process installation. They are a safe solution that helps avoid spine injuries and minimize dust generation.

Thanks to their modular design, they can be equipped with a number of additional devices such as: a compactor for empty sacks, a rare earth magnet, a rotary valve, a bottom suction unit or a screw feeder.

A built-in exhaust fan with a filter system with a reverse jet filter cleaning function help keep the equipment clean.

How does it work?

Step 1: the operator opens the hinged hatch that starts the exhaust fan.

Step 2: The operator places the bag on the station’s top inside the station, then cuts it open and pours the contents directly into the station’s tank (or the device below). The air flow generated by the exhaust fan causes the dust from the discharged material to be pulled into the center of the station.

Step 3: the dusty air is filtered through the cartridge filters inside the station. After unloading, the operator closes the hatch. The dust deposited on the surface of the filters is blown away by sequentially working compressed air nozzles. Automatic filter cleaning takes place only when the lid is closed and the fan is not running, so as not to create additional dust during unloading.
