CBI 5800BT Horizontal 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.

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.

The offset helix pattern promotes even wear across the rotor, so the customer spends more time grinding and less time changing teeth and screens.

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 for a variety of grinding applications.

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. The rotor adheres to CBI’s proven formulas for geometry and speed to maximize production rates while maintaining fuel economy.
