Thanks to the CASTULIK DX160 shredder and a mechanical‑thermal processing technology, the company REPARAF from Zohor (Slovakia) transforms hundreds of tonnes of waste into recycled paraffin and alternative fuel.

Knife mills offer a precise and energy efficient alternative to traditional single shaft wood shredders. Thanks to their small cutting gap, high rotor speed, and the close positioning of the knives to the screens, they produce a fine, homogeneous output with minimal dust. On the other hand, single shaft shredders, excel in robustness and resistance to metal contamination, but they tend to perform worse with fine fractions, wet wood, or fibrous materials. The choice of technology therefore depends on the type of wood, the required output size, material purity, and performance demands. The optimal solution is best confirmed by practical testing of the specific material on both types of machines.

Shredding of hazardous waste significantly reduces storage and transportation costs. See the experience of DETOX (SK) with the twin-shaft shredder DX160.
