Heavy-Duty Rotor Design
The disc-type rotor is assembled on a high-strength, alloy-steel shaft and mounted in self-aligning spherical roller bearings in rugged steel housings. Rotor discs are designed to allow maximum flexibility of hammer arrangements. A 12-pin rotor can be set up with six rows of hammers for premium efficiency, when shredding to a smaller product size.
Heavy-duty lugs are welded on the WB rotor discs for additional shredding and to assist with oversized pieces. Hammer pins are drilled and tapped to provide assistance and minimize downtime during hammer changes. All rotors are dynamically balanced to ensure smooth operation and long bearing life.
Jeffrey wood hogs are available with a standard rotor or with our SS design for difficult applications. The SS rotor incorporates heavier hammers to process larger, heavier infeed pieces. Typically, the hammers in this rotor are twice the weight of our standard hammers. Along with the heavier hammers, the rotor incorporates a larger-diameter shaft, thicker rotor discs, and larger hammer pins. The swing hammer design, unlike solid rotors, helps minimize damage when uncrushable material, such as steel, enters the rotor circle.
Hammer Design
There are several hammer designs available for both our standard and SS design rotors. The newest and widely accepted hammer is our Duratip® high-alloy hammer. Its replaceable tip design features increased shredding action and quick change-out during maintenance periods. Other hammers include hooked and reversible hooked designs, which are available in both hard-coated and Ultralloy® materials.
Hydraulic Bearing Removal
To substantially reduce maintenance time, the shaft is drilled for the hydraulic removal of the bearings. This, coupled with the housing’s fill blocks, ensures easy bearing removal without removing the rotor from the machine.
Liners
All liners are manufactured from thick abrasion-resistant steel plate to protect the hog from high impacts and normal wear. Liners are drilled, tapped, and bolted from the outside. This eliminates bolt heads on the inside of the machine, where they can wear and break off.
Steel Housing
The rolled-steel, structurally reinforced housings ensure long-lasting durability. Each hog’s fully lined interior guarantees that the housing will not wear from the inside when properly maintained. Doors on the upper housing provide access to the metal trap and to the interior of the machine.
Extended Lower Housing
Lower housing is extended to provide 180° of screen grate area. The extensive screen area reduces operating costs by allowing more open area in the machine, and it effectively discharges the material without causing a re-circulating load. Plus, the instances of plugging (from wet material) are greatly reduced. Center supports are incorporated for the screen grates. This helps maintain their integrity, and reduces bending and breakage.
Screen Grates
The Slant-Flow® screen grates are unique to our wood hogs. Unlike conventional screen sections, the Slant-Flow® design is angled into the flow of the material being shredded. This gives more shredding action and allows the material to evacuate faster from the machine. When the material is evacuated faster, the result is less wear on the screen grates and hammers, and a more uniform product size.
Screen grates are manufactured from heavy abrasion-resistant steel plate. The high hardness provides long life, especially in high-wear applications.
Tramp Metal Protection
Every Jeffrey wood hog has an integral tramp metal trap. This trap effectively collects the odd pieces of smaller tramp metal that can damage your wood hog. The tramp metal pocket is located in the back of the machine. As tramp metal enters the hammer circle, the hammers lay back and carry the material around to and place it in the metal trap.
New EZ AccessTM Models
The Jeffrey Rader Mini-Mill® and 30WB are available in an easy-access configuration for safe, fast, and easy access to the hammers, rotor, and liners.
