FEATURES

The JENZ BA 725 long service life. During the transition period up to the middle of 2015, JENZ will also be offering the BA 725 with the old MercedesBenz OM 460 engine as an option. The proven drive concept is also present in the new BA 725. Using the Vario-Flex control system, which is fitted as standard, the operator can adapt the engine speed to the material and therefore save fuel. This is also helped by the JES function which enables the entire unit to be run down to tickover at the push of a button if a short break in operations is required. The optional twin-gear gearing enables the rotor speed to be adapted to the source material in a range between 400-1,000 rpm. This makes applications from chipper operation up to composting possible.

Optimised material flow, more safety JENZ has used the necessary conversion to emission category Tier IV to further optimise other areas of the machine. For example, the draw-in height has been increased from 720 mm to 820 mm, and the top draw-in roller speed has been increased by 30%. This enables higher throughput rates and makes the machine more forgiving of irregular infeeds because the material is pulled apart by the roller. JENZ has also improved the proven IPS impact protection system to further reduce the risk of machine damage. If a foreign body enters the machine, the rotor stops, the crosspiece under the rotor swivels downwards and away, the draw-in runs in reverse, and the screen basket opens. This means that the foreign body is automatically slung out.

Simple screen basket changing In order to make maintenance and conversion work easier, JENZ is fitting the BA 725 with a threepart screen basket as standard. Each segment only weighs 25 kg and can be changed without any problems by only one person. Older machines can also be fitted out with this new screen basket if the frame is replaced. New screen baskets with larger openings are also available with immediate effect for the manufacture of coarser chipping material.

Improved control system JENZ has set the standards for operation of all machines with its ‘easygreen’ control system irrespective of whether the machine is a chipper, a biomass processor, or an HGV, power takeoff shaft or stationary machine. In addition to the well-known machine monitoring function, this controller also provides the operator with service and economic data. Job management is a new facility: the terminal allows customer and job data to be recorded, saved and subsequently transferred to a PC with a USB stick so that it can be displayed in Excel. The data can then be used to invoice the customer at a later date. Easygreen also makes error analysis easier. The terminal saves all the important operating parameters over a period of 10,000 operating hours. If there is a fault, JENZ customer service can access this data to limit the error as quickly as possible.

Extensive basic fittings The BA 725 is a powerful machine

for the professional processing of various forms of biomass. The range of use is large, and ranges from garden cuttings and organic waste treatment through fragmentation of scrap, trunk and root wood, up to processing substrate for biogas facilities. Due to the many possible task definitions, there is a whole series of additional fittings available for the BA 725. This includes a new, easilyfoldable conveyor belt with integrated under-ride guard. The machine is extremely stably-built in order to guarantee long service life. This all has an effect on the overall weight. For this reason the BA 725 is mostly fitted out with a tripleaxle chassis in the basic version. This means that the operator can obtain road traffic approval, even abroad in Europe.

The Bandit Model 2680 Track Beast Recycler is designed for tree services, loggers, governmental agencies, and land clearing contractors looking for a heavy-duty grinder that can be maneuvered around job sites. Production from the Model 2680 Track can exceed 300 yards per hour depending on the material being processed, which can include brush, logs, whole trees, stumps, logging waste, land clearing waste, construction and demolition debris, railroad ties, telephone poles, sawmill waste, pallets, slabs, bark, and chunk wood. This unit is effective in converting a variety of unwanted materials into usable products like compost, landscaping mulch, boiler fuel, animal bedding and more. It features a 24” diameter capacity with its 24” x 60” mill opening and engine options ranging from 440 to 540 horsepower. The Model 2680 Track sits atop a Caterpillar Model 320L steel track undercarriage with 600 mm, 23 5/8” wide track pads in either a single or double grouser format. The Model 2680 Track is equipped with the patented Bandit cuttermill, which has proven to be the most efficient means of breaking down a wide variety of

materials. With a Bandit cuttermill you have the option of cutting, splitting, grinding and chipping with the opportunity to mix and match cutting devices to allow for the production of uniform material with varying sizes. The cuttermill turns downward, which not only helps to pull material into the mill but also allows it to be positioned for a decisive splitting action similar to an axe rather than a more violent, intensive, and less effective hammering action found on other grinding platforms. The result is less vibration, less fuel consumption, and more structural integrity when compared to machines that carry more weight and horsepower. The Model 2680 Track features a 60-tooth setup on its cuttermill, allowing it to process a wide array of materials with ease with its 48” diameter by 63” wide dimensions. Different combinations and styles of cutterbodies and teeth can be configured to control the amount of bite, assist in forwarding material through the screening system, and dial in the preferred size and consistency of the end product. A chipper knife set-up can also be equipped on the Model 2680 Track, allowing it to produce a dimensional, screened chip that can be used for fuel and other applications demanding a consistent, high-quality, preciselysized chip. A single-speed 13’-6” long by 60” wide double slat design track-type infeed conveyor bed chain serves material to the cuttermill at 20 feet per minute on the Model 2680 Track, where it is captured by a 24” diameter x 60” wide internally driven floating top feed wheel. The cutting action is performed against the infeed chain which eliminates the need for an anvil, thus there is not a gap that is created between the chain and an anvil for materials to collect and wedge. Component weight is distributed and supported on a sturdy frame constructed from 1/4” thick steel with 20” deep formed high tensile steel plating and crosssection bracing using continuous welds for structural integrity as opposed to bolt-together techniques. Thus, the Model 2680 Track possesses the necessary physical reinforcement to stand tall for many years of service.
