Disc chippers are one of the most recently introduced wood chipping machines. It uses a flywheel made up of a large steel disk positioned at a 90 degree angle. Disc chippers also have chopping blades with slotted disks. The blades slice into the tips of the wood refuse as it is then pushed into the disk chipper on a roller belt. Oppositional cutting action is set by a knife, positioned in the throat of the disc chipper. The Knives in a disk chipper can be straight or curved in form, depending on the type of model. Blades are replaceable and can generally be sharpened for longer period of use. On the back side of the disk there may also be paddles to create airflow to help eject the wood chips. Disk chippers can also incorporate serrations to be set as sliver breakers that attempt to prevent the ejection of long slivers.
The size of chips made by a disk chipper are usually determined by the number of knives and their settings, the rotational speed of the disc and the material feed speed, which is usually determined by the feed roller speed. Differing these parameters or removing one or more of the blades in a multi-blade unit and blanking off the associated slot allows chip dimensions to be adjusted or sized.
The disc chipper is used for cutting logs, branches, planks, slab ,waste veneer ,bamboo, cotton stalks into uniform chips. The end result of the materials are great for parks, gardens, and landscaping.
