Wastewood Disc ChipperWastewood Disc Chipper

The high capacity, self-feeding disc chipper that processes all types of sawmill residuals without jamming.

The Nicholson Wastewood Chipper produces high volumes of excellent pulp chips from varied furnish such as slabs, edgings and lumber trims.

The chipper is designed to be fed by a vibrating conveyor.  A large, carefully designed infeed spout with non-jamming side wall geometry keeps all forms of material feeding.

This is a true self-feeding chipper and an operator is not required for most applications.
