A variety of tooth and screen options allow operators to tailor the end product to achieve their result. Despite its compact size, the RH1754 is outfitted with the same features found on larger grinders. A wide infeed opening accepts pallets and bulky material. Easily removable debris screens and reversing fans keep the radiator clear and extend service intervals. A magnetic head pulley on the discharge conveyor sorts out nails and light metals. And the screens can be changed in minutes to minimize set-up time. The towable version is light enough to be easily transported from on job to the next. For those that want the ultimate in mobility, the RH1754 is available on a heavy-duty steel track undercarriage.
The CBI Magnum Force 6800BT is specifically designed for land clearing companies and yard waste processors who demand high-volume throughput and maximum reliability. It is capable of processing land clearing debris, pallets, clean industrial waste, stumps and logs as quickly as it can be loaded. It’s well suited to produce highly-marketable mulch through its regrinding capability. The hog box features a clam shell opening to provide more room behind the screens for increased throughput and ease of maintenance. This design provides full access and a direct line to lift and remove screens. The push of a single button retracts the two main lock pins, and a second button activates two hydraulic cylinders that lift the entire upper section to a service-friendly vertical position. The hog chamber is a heavy-duty reinforced housing with 100 per cent continuous welds, providing maximum corrosion resistance, and the ultimate rigidity and strength.

The Beast Model 2460XP outperforms in its size class. The 2460XP is equipped with a 60” wide by 30” diameter cuttermill, a 60” wide by 24” mill opening. This machine uses a 30-tooth cuttermill running Bandit’s patented saw-tooth style cutterbodies that regulate the size of the tooth’s bite. Most of the material is sized in the initial cut, so material exits the large screening area quicker. Learn more about Bandit’s complete lineup of horizontal grinders, hand-fed chippers, whole tree chippers, stump grinders, track carriers, and attachments.
The Brunette Whole log Chipper increases revenue from your fiber supply to produce high quality chips. Designed with the knives extending the full face width of the drum, it produces more uniformed chips from tree length material. Features include easy knife change, wide throat infeed 26” x 40”, also equipped with both a top and bottom hydraulic driven powered feed works, this insures positive feeding of both short and long logs of all species. The drum chipper rotor can be adjusted for either conventional pulp chips or microchips suitable for pellet stock. Built as a modular design, the Brunette chipper can be supplied complete with infeed conveyor, chipper drive motor and hydraulic power unit, all designed on a uniframe suitable of containerizing.
Acrowood Slant Disc Chippers are available in 52”, 61” and 84” disc diameters. Knife arrangements include four, six or eight knife counts. The unique cutting action of the Slant Disc Chipper has made them a perfect choice for mini chip production, down to ¼” without the need for a feed works. The smaller chips are dried more easily and require less milling to be converted into a size suitable for pellet production. Pellet chips can be produced from logs or sawmill waste wood. Producing smaller chips using an Acrowood Slant Disc Chipper reduces the required horse power.
Whether your needs are converting waste wood to material for biomass energy, landscaping mulch, or livestock bedding, USNR has the experience and designs to suit each application.
