The DHM ensures best delamination results of complex compound materials and cleaning of mixed metals.

UMS-customer around the world value the exceptional performance processing e. g. shredder residuals, E-scrap (WEEE), populated and unpopulated boards, aluminum-copper radiators, aluminum scrap, Non-ferrous composites, fiber-metal-compounds, adhesive connections, vulcanized connections or productions scrap.

The DHM crushes the input material with fast rotating hammers smashing the material against the grinding tracks and material that is already inside the machine. Due to the permanent acceleration and deceleration of the material as well as the rolling between the hammers and the grinding tracks the material is mechanically stressed. This leads to a perfect delamination of the compound and a maximum cleaning of the surface. In addition, the material is transformed and homogenized regarding grain form and size. Hence, the processed and delaminated fraction is optimal prepared for all separation steps to follow.

The DHM is the key aggregate to enable successful high quality output fractions after delamination and subsequent separation, meeting the criteria for secondary raw materials or “end-of-waste”. This is the major plus of the DHM compared with conventional shredders, which can shred smaller but do not change the nature of composites at all.

The heavy construction, derived from UMS's ore processing experience with screwed wear plates inside makes the DHM relatively insensitive to impurities in the material. Further advantages are an easy adaptation to many different types of input materials, high-energy efficiency, ease of maintenance, low tool and wear and tear cost as well as a long lifetime.

The range of application starts from coarse (input size approx. 80 mm) down to fine and superfine mills for special cases. The DHM is available in different sizes.
