Hard Material Separator

Typ HSA

The HORSTMANN hard material separator separates impurities such as metals and stones from the input fraction. These differ in their high specific weight compared to the residual material fraction (e.g. 60 mm). The separated waste is divided into an impurity fraction (hard materials) and a cleaned fine fraction.

The fraction to be treated is fed to the hard material separator via a feed belt in the area of a material transfer. In the feed hopper there is a baffle plate which guides the material onto the separating drum. This rotates in the same direction as the material flow. The heavy contaminants bounce off the separation drum and fall past it against the material flow. The remaining material is carried along by the rotary motion of the separating drum in the other direction and then transported further by a conveyor belt.

The impurities fall by impact onto a discharge belt below the hard material separator or alternatively directly into a container. An optimum separation result between fines and impurities is achieved.
