Drum chipper

Drum chippers are key pre-processing equipment in feed production. Their core working component is a high-speed rotating drum equipped with flying knives. These knives, acting in shearing action with bed knives, cut long-fiber materials like straw and grass into uniformly sized pieces. This equipment features a sturdy structure, high production capacity, and stable operation. It effectively meets the material form requirements of subsequent processes and is a crucial component in ensuring high-quality feed production.

Equipment

Description

Drum chipper are specialized equipment for producing high-quality wood chips, suitable for paper mills, particleboard and fiberboard plants, and wood chip production and export facilities. They can cut logs and small-diameter wood into high-quality industrial chips with uniform length, smooth cuts, and thickness. They can also cut branches, boards, and other materials.

The machine base is welded from high-strength steel plates and serves as the support for the entire machine. Two, three, or four flying knives are mounted on the cutter drum, secured to the drum by specially manufactured fly bolts and a knife block. The upper feed assembly is hydraulically adjustable to adjust the thickness of the material being cut. Acceptable chips fall through the screen and are discharged from the bottom, while larger chips are further chipped within the machine.

The hydraulic system: Oil is supplied from the pump to the cylinder, which activates the cover to facilitate blade replacement. During maintenance, the upper feed roller assembly can be lifted to facilitate adjustment of the spacing between the flying knives and the bottom knife, as well as removal and installation of the plate.
