Back to Chipping

Long logs expertly handled with horizontal feeds

Our disc chippers produce high-quality wood chips that meet the exact specifications of various industries. Over 60 years of continuous development and experience from applications in the board, sawmill, pulp and paper, and bioenergy sectors have resulted in a highly flexible machine program for all possible customer requirements.

Bruks Disc Chipper horizontal

For wood-processing operators that predominantly handle longer logs, we have the ideal disc chipper. The horizontal-fed Bruks disc chipper is particularly well suited for long logs as well as cut offs and slabs, including conversion of any sawmill residues. All wood products are processed into quality chips that are used for the pulp and paper industry.

Our wide product range starts with small diameter discs, up to high-capacity chippers with disc diameters of up to 3.0m and 2,500kW of installed power. Bruks horizontal-fed disc chippers can process up to 650m³ of chips per hour, with adjustable chip lengths from 20-50mm. Options are also available for different knife arrangements.

Safe knife control

All our larger disc chippers have a knife holding system to make handling the knives as easy and safe as possible. The knives are fitted in two sections and mounted in cassettes so that light-weight knives can be used.

Knife length can be adjusted using screws prior to fitting, which ensures the correct knife length as well as fast and easy knife changes. Chip length can be altered by changing knife shims and moving the disc. As an optional extra, the disc on our largest chipper can be rotated for a knife change via an electro-pneumatic inching drive.

When knives need to be changed, the chipper hood is raised hydraulically. However, to maximize safety, it is locked while the chipper disc is rotating and cannot be opened until the disc has come to a dead stop. Furthermore, the chipper cannot be restarted as long as the hood is open.

Maximizing wear parts

Like our entire wood-chipper range, we have focused our designs on maximizing the service life of wear parts. The horizontal-fed Bruks disc chipper has a heavy-duty design, easy access for maintenance and replaceable wear parts that ensure long machine life and maximum availability.

All wear parts on the chipper are generously dimensioned and easily exchangeable. Bolted wear plates in sections protect the chipper’s in-feed side of the disc and their fittings make them easy to exchange when needed. The same applies to the bolted wear plates on the base and side of the feed chute.
