Drum Chipper with horizontal infeed

These horizontally fed chippers have extra wide throats for smooth feeding of roundwood, slabs, edgings, reject boards, trim ends and veneer residue. The chips can be discharged through a bottom screen or blown out via a fan to a chip screen. With power ratings up to 1000 kW and infeed openings up to 850x1200 mm, the BK-DH drum chippers can be used for a wide range of applications.

Subject to technical modifications
Capacities and power demand are depending on chip lenght and kind of infeed materials.
These benchmarks are based on a chip lenght of 30 mm and a common mix of softwood and hardwood.
The production of micro chips leads to a higher power demand by lower of capacity
