Chippers are used to process trees, stems, logs or blocks into wood chips for making pulp and paper.

A chipper consists of a housing containing a rotating disc.  Chipping knives, counter knives and clamps are mounted to the chipper disc.  As fibre is fed into the chipper it is chipped to the length determined by the setting of the distance of the chipper knife to the chipper disc face plate.

There are several types of chippers.  Disc chipper, slant disc chipper and drum chippers are the most common type.  Drum chippers are primarily used for trim blocks while disc chippers are used for whole log chipping and chipping of longer materials including whole log chipping and edger tailings.  Chippers can be horizontal feed or drop feed.
