RECEIVING RAW MATERIALS

Sack tipping station

Bag tipping stations (10 kg, 25 kg, or 50 kg) are defined by the term bag tipping stations. The operator empties the sacks into a hopper with a lid. The height of the visor, where the operator rests the bag, should be close to 80 cm. Usually the operator, after temporarily fixing the bag, cuts a slit in the bag with his knife so that he starts emptying the product into the hopper. There is a suction nozzle to guide the generated dust to a filter. There may also be plastic blinds, which will prevent dust from escaping. It is useful to have a min. level sensor, which alerts when the hopper is empty. At the outlet of the hopper can be placed a conveyor like an auger, rotary valve, air transport system, etc. It is useful to have a protection grid so that no foreign particles fall into the bag tipping station.

Big-Bags emptying station

Octabins emptying station

The Octabins emptying station is similar to the Big-Bag emptying station. By the term Octabins, we mean the 1 m³ octagonal cartons that have a plastic bag inside, mainly for pellets. The steel frame supports a suction nozzle.

Towards the bottom of the Octabin, a special mechanism tilts the Octabin and achieves perfect emptying with suction.

Big-Bags filling station

To fill Big Bags, a steel frame is needed, which keeps the Big Bags upright and open. An important role is played by the correct positioning of the bottom. It should not fold somewhere, but instead should stand upright.

In many cases, it is requested to weigh the bulk bag, usually with a suspended arrangement on 4 load cells. The weighing issue is more complex because the Big Bag must be held tight to fill properly, but not so tight-suspended as to affect its weighing.
