Tanks that can store the powdery raw material.

The availability of silo storage, means material is not exposed to dirty areas as with the traditional bags. They take up less space and can be located in any neutral area of the factory.

Reduces the costs of the product as it is purchased in bulk thus avoiding packaging.

The silos have to be suitably designed taking into account the properties of the bulk materials and process requirements.
