Lump Breaker

The smallest achievable grain size range is from 0.5 to 15 mm. The rolls are able to run both synchronized or in friction modus, i.e. with different speeds for a ripping effect. To prevent a build-up of input material at the spiked rolls, the Breaker comes along with built-in scraper blades and has an optional anti-blockage and reversing control.
