watch it shred!

Chained up! The powerful and flexible chain impactor is suitable for crushing different materials such as electronic scrap, cooling systems, freezers, RDF scrap, or biomass. There are no cutting tools, such as rotating or fixed blades and granulating sieves. By colliding the accelerated feed material against itself performs approximately 80% of the reduction. The accelerating tools can be changed in less than 15 minutes. Optimal disintegration of the composite materials in an extremely short time with very little wear.
