SACK DISCHARGE STATIONS, MANUAL DISCHARGE BUNKER

In order to transfer these raw materials into the storage silos, special equipment according to the type of material are required. These are equipment where the material in the sack are discharged and then transported.

These equipment are in different types and constructions depending on type of transfer (vacuum or pressure), form of the material to be transferred (granular or powder).

Manual discharge bunkers – If manual sack discharge systems are used for transfer of micron-sized materials raising excessive dust, it should be equipped with a filter having suction feature to prevent dust raise. Otherwise, the operator pouring the product may be exposed to the dust in the environment. And this is of course not a healthy method.
