Chipping and debarking technology

ANDRITZ sawmill products include debarking and chipping equipment.  All sawmill chipping products, like the PowerHead canter, use the well-known TurnKnife system. This equipment is in use in sawmills around the world – operating on various wood species in a variety of climates. The technology is proven, robust, and highly efficient.

Chipping products

Canter heads for plane reducers

The PowerHead is a solid canter head that fits most of sawmill canters on the market. PowerHead is designed to provide optimal operating conditions for the well-known TurnKnife System III (TK-III). The combination of a PowerHead and TK-III delivers uniform and high chip quality, a long knife running time and requiring minimal maintenance or service. The PowerHead is adapted for SCAN-CM 40:01, a standard method for classifying cellulose chip size fractions in many countries around the world. The PowerHead is available with from three to eight "knives" in face knives or face saw versions.

TurnKnife systems for drum and disc chippers

The TurnKnife is a high-quality knife system that, due to its special design and manufacturing precision, produces chips of the best quality over a long period of time. The system is based on an easily manageable knife with two edges.

Produced from the highest quality alloy chromium steel, the knives are specially treated during manufacturing to provide a much longer edge life than conventional knives. The TurnKnife has a double-edge and is reversible which eliminates knife grinding. The patented shape design ensures precise and consistent knife location to maximize chipping performance.

Upgrading a chipper with the TurnKnife system improves chip quality and chipper performance with excellent economics.

Debarking products

Tools for Cambio* debarkers

Campro is a high performance debarking tool, which comprises debarking tips and advanced tool holders. Its superior strength and lower weight result in a smoother debarking operation by reducing tool tension. The W-shaped profile adds strength and efficiency, reducing maintenance costs and increasing productivity. Since it can be easily adjusted to meet a variety of working conditions, Campro debarking tools deliver cleanly debarked logs.

The design of the Pyramo tip ensures that it is always accurately positioned in its holder. Errors in tool circles and tool lengths are virtually eliminated, thereby producing better debarking results. The superior debarking edge of the four-sided Pyramo tip, as well as the correct angle, allows for increased capacity through the debarker. Pyramo tips allow a worn edge to be replaced in a simple operation with minimal production downtime.
