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
