Our machines are ideally suited to producing crushed sands. Not all sand is the same, and the shape and composition of many naturally occurring sands is unsuitable for the construction materials industry. Discover an economical process for producing sand with consistent properties. Our process stands out thanks to its high quality and the responsible use of resources it unlocks.
Our rotor impact mill (type RPM) and rotor centrifugal crusher (type RSMX) crushing systems ensure best results in the production of crushed sand. Both machines operate based on the impact principle and have a rotor with a vertical shaft. This enables you to achieve high sand yields and the desired cubic particle shape. The adjustable speed furthermore allows you to configure the grading curve of the end product according to your requirements. With both machines you can rely on a constant grading curve of the output material over the entire service life of the crushing tools.
Since the end of 2022 the Ernst Derfeser GmbH relies on a BHS rotor impact mill of type RPM 1513 for the production of sand at their quarry in Vomp (Tirol). The video shows a short overview of the plant with the BHS crusher.
