6300B Drum Chipper

6300B Drum Chipper


The 6300B Drum Chipper is suited for high volume biomass producers who have a wide variety of feed material, from logs up to 36″ (91 cm) in diameter, to brush and small feed stock.

The 6300B Drum Chipper is powered by a 1050 HP (772 kW) C27 Caterpillar engine, and has an optional Tier IVi engine available. A PT Tech wet clutch has also been added to the machine. At 85,000 pounds (38,555  kg), the 6300B was designed for operations requiring high production and frequent moves between jobs.

The 6300B Drum Chipper has two drum configurations, a 8-pocket drum to make standard biomass chips, or a 16-pocket drum to make a microchips.  An optional grate system has been redesigned to allow for adjustment from a microchip to a 1¼” chip with the same grates. Traditional Babbitt type knife systems are standard equipment, or an optional key knife system is available. Peterson’s chip accelerator system, adds load density, or throws chips well away from the machine for land clearing operations.

The chipper utilizes a 50″ (127 cm) diameter by 60″ (152 cm) wide drum. Other key features include a sloped feed deck for the ease of feeding and wear resistant AR450 wear surfaces on the drum pockets and shell. The feed chain has been upgraded to WDH120 for improved strength and long life.

Since 1981, Peterson has specialized in the developing of delivery and processing equipment that turns low-grade organic materials into high value products.

Knife Assemblies: At The Heart Of The Chipper

Produced from the highest quality alloy chromium steel, heavy-duty Peterson knife assemblies achieve uniform production of wood chips with high accepts and minimal losses.

Select From 8 or 16-Pocket Drum Styles

Featuring durable AR450 wear surfaces, the 4310B comes standard with a 6-pocket drum rotor with one Babbitted knife per pocket. A 12-pocket drum rotor is available for chipping microchips.

IQAN Operating System

The robust and reliable IQAN operating system is easy to use and is weatherproof for the most extreme environments, providing self-diagnostics and engine and system parameters.

Superior Product Sizing

Peterson’s secondary grate system provides ultra-consistent chip sizing; twigs and small stems which can be difficult to size are easily fractured through our innovative system.
