BIOMASS - ASTEC
Drop the Downtime
When the Peterson 4310B drum chipper came on the forestry scene 13 years ago it set a new industry standard for drum chipper efficiency. Not only does this machine process biomass materials at highly competitive rates, but the proprietary design also boasts excellent fuel efficiency. This power comes packaged in a compact and agile design that allows for optimum maneuverability in the field. Be it the machine or the end product, quality matters. There’s no question why this is the professionals’ choice.

The Hardware The Peterson 4310B drum chipper is suited for highvolume biomass producers who process a wide variety of feed materials from brush and small feedstock to logs up to 24 inches (61 cm) in diameter. At 58,500 pounds (26,535 kg), the track-mounted drum chipper is designed for operations requiring high production and frequent moves between jobs and is powered by the C18 Caterpillar engine (755hp).
The chipper utilizes a 36inch diameter by 44¾ inch (91 by 114 cm) wide drum with either six or 12 knife pockets. Chip length can be set from 1⁄8 to 1¼ inch (3 to 32 mm) depending on rotor and knife configuration. The chipper’s robust knives are the thickest in the industry, with a reputation for exceptionally long life. Three, 3/4” bolts clamp down each knife for superior strength and safety.
Other key features include a hydraulic clutch, a sloped feed deck for ease of feeding and wear-resistant AR 450 wear surfaces on the drum pockets
and shell. Optional materialsizing grates further reduce oversized twigs and branches in the chips. The machine can be further customized by adding on a chip accelerator to achieve maximum loading efficiency. The end load spout comes standard with an optional, top-loading spout available.
The Process It sounds simple. Materials are fed into the machine, processed into chips then blown out the other side. For those using the 4310B for the job, it can feel that simple as well. Engineered for maximum efficiency, there’s a reason so many rely on this specific machine to get the job done.
The process begins with the sloped feed deck designed to make for easier feeding of various species of feedstock. Unlike disc chippers that are made to process clean, straight logs, drum chippers are made to handle less uniform feedstock including limbs and bark. The design of the feed deck, along with the feed chains and compression roll, ensures a simple and smooth initial feed. As material is fed into the machine, the compression roller feeds the stems into the drum chipper assembly to be processed.
The drum in the center of the machine can be configured to run six or 12 knives (depending on the application). As the drum spins and materials fill the pocket below the knife, the knives cut the materials into a finely calibrated size. The resulting chips are then thrown through the grate, which prevents twigs and small-diameter stems from passing through. The chip accelerator forces air into the chip spout, increasing the velocity of the chips exiting the machine. This increases load density by packing the chips into a chip van, or if in a land clearing application, redistributing chips back into the forest. This is key to loading efficiency and can load up to an additional 10 tons of material into a container.
The End Product Drum chippers are known for producing materials for use in specific applications. Depending on the goals of the project, producers may The Peterson 4310B drum chipper is suited for high volume biomass producers who process a wide variety of feed materials from brush and small feedstock to logs up to 24 inches (61 cm) in diameter
elect to simply blow the chipped materials back onto the property being cleared. Often though, there is value in other applications for these finely made wood chips. In these situations, the optional top-load spout can be added to allow for loading materials for transport.
The most common applications for biomass materials include various landscaping uses like erosion control, playground mulch or decorative mulch. These chips can also be specifically sized for use in filtration systems. However, the most common and dynamic application value right now is in biomass energy. As the world energy market continues to fluctuate, many producers of biomass materials are finding increased demand for use of their products as renewable energy. Operator Experience Every Peterson 4310B drum chipper comes standard with wireless remote-control capabilities allowing for single-person operation and total control in the palm of your hand. The IQAN control panel features a user-friendly, touch-screen design and allows for fine adjustments for maximum productivity.

With JENZ shredders through the energy crisis
JENZ biomass processors have always been designed to cover flexible areas of application for biomass as an energy source. Even more flexibility will be required in the future with increasing electricity and gas prices. On the one hand, the full use of wood as a raw material is becoming more and more important and on the other hand, in the wake of the gas shortage, electricity generation from biogas is to be promoted more strongly in the future. In order to actually achieve these two goals, JENZ biomass processors are equipped with various features or can be used for completely different processes by quickly changing tools and screen baskets. On the following pages, the production of biomass fuels and biogas substrate is presented in a hands-on manner.
The importance of biomass fuels is increasingly coming to the fore as the price of fossil fuels rises. In addition to the highquality “premium woodchips” produced from round energy
What can be processed?
• Waste wood class I-III • Leftover wood from industrial wood processing • Crosscut wood • Bark wood, materials that are difficult to recycle can and must also be processed as fuel in the future.
• Branch and shrub cuttings • Woody components from green waste composting • Roots • Logs
And how?
BA 926:
The BA 926 is primarily the first choice for the permanent production of biomass fuel thanks to the TwinGear system. This unique system enables speed reduction to produce ligneous biomass.
BA 1016:
With 812 hp drive power and a particularly heavy rotor, the BA 1016 large shredder is the expert if you need to process particularly demanding material, such as waste wood, roots, cross-cut timber, etc., and you want to achieve enormous throughput rates.
BA 615 and BA 916:
Likewise good fuels can be produced from, for example, woody green cuttings or pre-broken roots with the two smaller machines by installing fixed tools.
Fixed tool easycut:
Converting to fixed tools with a blade makes it possible to achieve a defined and precise cut of the hard material when processing ligneous biomass. (Conversion time depending on machine type: approx. 2 - 2.5 hrs - No rotor exchange required)
“Biomass and Residual Wood XL” screen basket set
JENZ has developed a screen basket with slats especially for fuel production. This ensures the best chipping results without overlengths by holding back material which is too long and causing the material to be cut further.
Lower draw-in roller:
Adopted from chipper technology, an additional lower draw-in roller on the BA 926 and BA 1016 ensures controlled material feedin, e.g. with long logs or root end pieces. This in turn leads to good chipping results.
Practical example
Biogas substrate
Biogas plant operators are facing the challenge this year that yields from maize as an energy crop are much lower than usual. At the same time, the biogas industry hopes for an expansion of biogas production to counteract the energy shortage. To ensure that biogas plants can also be utilised more efficiently with lower maize yields or overall, other interesting raw materials, such as maize straw or solid manure, must be considered as gas producers. Thanks to a total of four tool layouts, JENZ biomass processors can fibre almost any material and thus make the most diverse substrates available for the biogas plant.
What can be processed?
• Crop residues such as straw (maize, grain, ...) • Grass or maize silage • Dung • Sugar beet, potatoes, carrots, ... – Coarse shredding for silage heaps – Fine preparation for lagoon storage (pumpable) • Organic waste • Waste from the food industry (chocolate, wafers, bread, ...)
And how?
BA 615:
The compact shredder with 306 hp and an inlet opening of 615 mm is aimed primarily at smaller (contract) operations or local authorities. Thanks to its low tare weight of only 11.5 t and a low infeed height of 1.86 m, the BA 615 can be easily transported and loaded with small tractors such as tractors or wheeled loaders. With a rotor speed of over 1,100 rpm, the smallest JENZ shredder is ideally suited for substrate processing.
BA 916:
530 hp, 19 t total weight and 10.40 m transport length - that’s how the substrate and green waste specialist scores points. With a rotor speed of over 1,100 rpm, the BA 916 achieves particularly fine fibration, especially with difficult material (e.g. manure). The sideways swivelling outfeed belt and the standard tool box enable a quick changeover when changing material.
BA 926:
Anyone who focuses on the production of biogas in addition to the production of biomass fuels requires a multifunctional machine. The solution: the BA 926 with TwinGear drive. This unmatched system offers a total of four working speeds and thus a quick change between chipping and shredding operations. The BA 926 can be switched to substrate shredding at the touch of a button, where fast speeds are used for defibration.
BA 1016:
The largest JENZ shredder scores points above all for its outstanding throughput performance. For this reason, it is used where either hard, difficult material or particularly large quantities of material have to be processed. For example, over 200 t/h can be achieved when processing manure.
Practical example
HEIZOMAT has developed a new rotor for the HM 14-860 K woodchipper. With an infeed width of 1200 mm, this newly developed chipping rotor has only 6 exchangeable blades. With this chipping rotor, wood chips can be produced for small wood chip heating systems as well as coarse wood chips for large heating plants. The 8 mm thick blades can be easily resharpened when installed.
Since the rotor speed has been reduced, a total number of 6 throwing shovels in the discharge fan now ensure smooth discharge of the woodchips. The rotor is driven in the usual way by the gearbox-independent power take-off (NMV) from Mercedes with subsequent speed and direction of rotation conversion by the proven elastic belt transmission from Heizomat.
The Mercedes Benz AROCS 3353 engine with a drive power of 530 hp ensures the fuel-saving drive of the woodchipper.

Black Bruin strongly involved in the development of Ponsse’s HH360 rotator
Forest machine manufacturer Ponsse is launching the new HH360 rotator which lets the harvester head freely rotate 360° degrees without limitations. The product has been developed in close cooperation with Black Bruin and Ponsse has exclusive rights to the product in forest machine use. The innovation was on show for the first time at the Expocorma trade fair in Chile on November 23-25, 2022.
According to Janne Loponen, Ponsse’s Product Manager for harvester heads, the 360° degree rotating harvester head speeds up wood processing, makes the operator’s job easier and reduces hose failures. “Compared to competing products, the rotator used in this innovative solution is strong, powerful and above all, energy efficient,” says
Black Bruin’s R&D Manager Tero Ylä-Mononen
Loponen. “The project with Black Bruin has progressed smoothly all the way and the cooperation has been highly productive.”
Black Bruin’s R&D Manager Tero Ylä-Mononen is also highly satisfied with the outcome of the cooperation and elaborates on the advantages that can be achieved with the HH360 rotator: “The HH360 is a combination of the wellknown and durable radial piston technology of Black Bruin’s harvester rotators and Ponsse’s innovation. Thanks to the structure, the torquetransmitting components are wear-proof and the rotator maintains a firm grip throughout the machine’s service life. The rotator is extremely accurate in use and responds precisely and consistently to the user’s actions. That’s what makes controllability of the harvester head natural and superior in all situations.”
Due to the radial piston rotator’s very high efficiency, just 20 l/min of oil flow suffices to operate – yet another factor contributing to the forest machine’s total economy. The rotator’s operating costs are low and it is easy to service if needed. This means that service life can be extended far into the future. “We are also pleased to make our own contribution to support the key properties offered by Ponsse’s harvester head solutions, that is, productivity and reliability,” continues Ylä-Mononen.
The powerful and exceptionally energy-efficient HH360 rotator is available for multiple Ponsse harvester heads when mounted as a loose head installation. The innovation was on show for the first time at Expocorma in Chile.
