Light contaminants such as foils, plastics, and wood do not belong in secondary coarse aggregates, which are used for concrete and mixed granulate, among other applications. One of the main challenges in recycling construction materials is reliably separating impurities from reusable and valuable minerals.

An ideal processing plant must excel in multiple areas. To operate sustainably and cost-effectively, reliability must go hand-in-hand with effective technology, user-friendliness, and a robust design. The wash-bear® combines simple technology with impressive efficiency to separate these light contaminants from valuable granulate.

The operating principle of the wash-bear®, even after 15 years, remains one of the most reliable—and therefore most successful—methods for removing contaminants from granulate.
