Patented Slab Ramp

Our patented slab ramp creates an optimal feeding angle for slabs to maintain steady processing rates. Equipped standard on all our mid-sized and larger models, this exclusive feature allows our grinders to process green pliable slabs that can instantly plug other machines. The slab ramp quickly adjusts to create a more aggressive feed angle for larger diameter feedstocks.
