Slab Ramp

Our patented Slab Ramp offers a simple, yet remarkably effective method for controlling feed rates with pliable feedstocks like slabwood, palm fronds, tomato vines, and other materials that plug other grinders instantly.

Controlled Feed Rates

The Slab Ramp is an adjustable anvil that lets the operator hydraulically change the angle at which feedstocks encounter the grinding rotor. Raising the Slab Ramp brings the shear plane closer to the rotor, creating a more conservative grinding angle for pliable feedstocks. Lowering the Slab Ramp creates a more aggressive grinding angle for solid feedstocks like pallets, C & D, and logs. This quick and simple adjustment can mean the difference between downtime and steady, efficient production.
