Model 4680 Track – Self-Propelled Beast Recyclers / Horizontal Grinders
The Model 4680 Track Beast Recycler is the largest and most productive horizontal grinder in the Beast family. With recorded production numbers of around 800 yards or more per hour, this unit will convert large diameter stumps and whole trees into quality end products in just one pass. Add mobility in the form of a steel-tracked undercarriage and the task of skidding and forwarding materials is eliminated, making this machine appealing to land clearers. Recycling yards and landfills can also rapidly process piled brush, whole trees, stumps, pallets, land clearing waste, palm fronds, logging slash, sawmill waste, construction waste, and housing demolition. It features a 45″ diameter capacity with its 45″ x 60″ mill opening and engine options up to 1,200 horsepower.
The Model 4680 Track is equipped with the patented Bandit cuttermill, which has proven to provide 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 self-propelled Model 4680 features a 60-tooth setup on its cuttermill, allowing it to process a wide array of materials with ease with its 60″ 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 4680 Track, allowing it to produce a dimensional, screened chip that can be used for fuel and other applications demanding a consistent, high-quality, precisely-sized chip.
A three-speed 16′-5″ long x 60″ wide double slat design track-type infeed conveyor bed chain serves material to the cuttermill at 18 to 43 feet per minute on the Model 4680 Track, where it is met by a 36″ diameter x 60″ wide internally driven floating top feed wheel in an arrangement that is easy to feed. 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 3/8″ thick steel with 22″ deep formed high tensile steel plating and cross-section bracing using continuous welds for structural integrity as opposed to bolt-together techniques. Thus, in combination with three 25,000 pound air-brake axles, the Model 4680 can provide the necessary physical reinforcement to hold up for many years of service.
When it comes to determine how you want your material delivered, the Model 4680 Track offers plenty of choices when it comes to discharge options. The standard folding discharge conveyor feeds material at either 280 or 480 feet per minute, includes a magnetic head pulley for retrieving metal fragments or nails out of the flow of ground product, and has an approximate stacking height of 18 feet. The primary discharge conveyor is 10′ long x 56″ wide and the secondary discharge conveyor measures in at 25′-6″ long x 56″ wide. For broadcasting chips over a site or loading end-opening chip vans, you can opt for an 18′ long discharge with a 42″ diameter hydraulic thrower. This device is mounted at the end of the conveyor and will swing 25 degrees side-to-side (50 degrees total), 34 degrees up, and 12 degrees down to give you directional control of placing your chips. Other discharge options include pivoting and height-adjustable conveyors to suit your operation.
The Model 4680 Track is designed to travel over rough and uneven terrain virtually impossible for other grinders to traverse. A Caterpillar 325EL steel-tracked undercarriage gives this unit stabilty and durabilty for those tough grinding applications. Customers can choose between steel or rubber 700 mm, 27-1/2″ track pads with a triple grouser configuration.
Many items that are optional on smaller Beast units already come standard on a Model 4680 Track. A radio remote control with tether remote back-up and 50′ of cord can be used to control all yoke, infeed, discharge conveyor, gate, engine, track, and emergency stop functions of the machine. A Flexxaire auto-reverse cooling fan prevents engine overheating, improves machine efficiency, and reduces fuel consumption. An air compressor with 13 horsepower gas engine is also part of the standard build for providing tools at the machine. Also included are dual front hydraulic stabilizers, electric over hydraulic shut down switches, a fire extinguisher, lockable control cabinets, and a liquid dust suppression system.
Customize your self-propelled Model 4680 Track to the fullest with many productivity enhancing options. For sizing material, select from a variety of square, rounded, baffled, or diamond screens ranging from 5/8″ to 7″ in diameter and gates up to 5″ in diameter. Other add-ons worth considering are a wide flair infeed style and a flow control kit for the infeed and feed wheel. A full palette of standard and custom paint colors give you the freedom to choose the look of your brand or company.
Versatility is defined by the Model 4680 Track. The unit can be configured specifically for shingle grinding with technology that allows a hot mix asphalt supplement to be produced in one-pass during any season. For wood materials, an optional self-contained coloring system can help prepare mulch directly for the market. A knife configuration on the cuttermill can essentially convert your Beast into a whole tree chipper for producing valuable products for energy industries.
The Model 4680 Track, as with all Bandit Beast Recyclers, is designed and equipped with operator safety, user-friendly control, fuel efficiency, and simplified maintenance in mind. Components that are easily accessible save time on routine maintenance schedules and reduce downtime by being more serviceable out in the field. Feel free to contact a sales representative and ask about fuel savings statistics and production numbers based on your individual situation and needs. These factors, in combination with above-and-beyond factory support for your success, have proven over time that choosing a Bandit Beast Recycler is the best economical decision you can make for a long-term investment in a horizontal grinder.
