Classification of chipper blades

The chipper blades can be divided into two categories according to the mechanical structure: disc chipper blades: the cutting blades are mounted on the disc, and the disc chipper.

The disc chipper blade is mainly used for cutting logs, and the quality of the chip is better, and it is used more in the pulp and paper mill; the drum chipper blade: the cutting blade is mounted on the cylindrical drum, and the drum chip is used. The machine blade has wide adaptability to wood varieties and can be used for various wood materials such as board skin.

The chipper blades can be divided into three types: ordinary machining (4 to 6 knives), multi-knife structure (8 to 12 knives) and spiral surface structure. The three types of chipper feeding methods include oblique feeding and flat feeding (or horizontal feeding). The long shavings of long logs are usually fed with flat mouth. The shavings of short logs and slabs can be fed with oblique mouth or flat feed.

Under normal circumstances, the chipper blade is made of alloy tool steel. After professional heat treatment, the hardness of the knife edge is HRC55-58°. It must ensure long-term sharpness and wear resistance of the cutting edge to ensure the quality and production efficiency of cutting chips.
