Bruks drum chippers, with their large in-feed openings, lead the market and are capable of processing any waste wood product. Logs or bundles of wood with a diameter of over a meter can be reliably processed in larger chippers.
With the ability to produce up to 300t/h of high-quality pulp mill chips, or smaller microchips for use in the bio fuel industry, our drum chippers have flexible arrangements to produce even large chips of up to 200mm in length.
Chippers have heavy-duty, self-aligning bearings that are centered in steel housings and bolted to the side walls of the machine. These deliver a long and effective service life.
In addition, their feed rollers have special ‘teeth’ that are surface-hardened by a heat treatment process, resulting in a particularly high wear resistance. Rollers can be delivered with the option to have exchangeable wear segments.
Hydraulic or pneumatic cylinders are used to regulate the pressure of the upper feed rollers and to open the upper feed rollers for maintenance easy cleaning. Hydraulic cylinders are also used for maintenance functions and easy access for cleaning and knife change.
