CBI 5800BT Portable Upswing Grinder

Horizontal Wood Grinder

A versatile horizontal grinder

No other horizontal wood grinder cures the headaches of load restrictions and permitting as much as the CBI Magnum Force 5800BT Portable Upswing Grinder. This portable horizontal grinder was developed to feature the same principles of the proven CBI 6800BT Grinder but is purpose-built for contractors dealing with transportation restrictions. Like CBI’s other horizontal grinders, the 5800BT never compromises strength or performance.

More than your average wood waste grinder

Built to reduce the customer’s total cost, replaceable 1” thick Hardox 450 wear liners fully protect the inside of the grinding chamber and simplify maintenance. Other features include a 30” diameter upper feed roller with a built in high-torque hydrau­lic motor, hydraulic up and down pressure, and 20 weld-on hammers with bolt-on reversible tips. Tips are arranged in a patented offset helix pattern that cuts the full width of the rotor, drastically increasing throughput over the competition’s conventional pinned rotor design. The offset helix pattern promotes even wear across the rotor, so the customer spends more time grinding and less time changing teeth.

CBI’s Replace-A-Face™ hammer system allows operators to swap out the face inde­pendent of the rest of the hammer for quick, easy, and inexpensive repairs. Different tip widths and heights are available to change the cutting gap. The upper feed roll pivot also has replaceable wear plates. The rotor housing features the same spider bracing, rugged bearing housing, and cross members as CBI’s larger machines. All holes are line-bored to the highest tolerances, ensuring long bearing life and that parts fit for the life of the machine. The rotor adheres to CBI’s proven formulas for geometry and speed to maximize production rates while maintaining fuel economy.

Serves as a superior asphalt shingle grinder
