High Performance Crusher. Redefined.
ONE CRUSHER FOR EVERY APPLICATION
The Crush + Size DRC is a completely new type of roll crusher that removes the traditional limitations of double roll crushers. It combines the direct-drive principle of a sizer with the adjustable crushing gap of a classic double roll crusher – a combination that has not existed at this level before. Slow-running, precise, and fully adjustable.
The result: a machine that combines the best of both worlds – the gentle, efficient crushing process of a roll crusher with a reduction ratio you would expect from impact or cone crushers.
ADJUSTABLE SIZER
Conventional double roll crushers couldn’t compete with jaw crushers, cone crushers or impact crushers when it came to reduction ratio and the handling of hard materials. That’s changed.
The DRC series combines the inherent process advantages of roller crushing with a significantly higher reduction ratio – making it a more efficient alternative that delivers real advantages in production. Compared to standard roller crusher solutions on the market, the DRC stands apart with a higher reduction ratio, higher throughput capacity, and the ability to handle even the hardest materials.
Integrated overload protection allows even materials with a high proportion of foreign objects to be processed without interruption.
