CBI 6800CT Horizontal Grinder

Once land clearing and wood waste professionals switch to CBI grinders for their ultimate production, performance, and durability, they never look back.

Improving on the 6800BT’s revolutionary design, the 6800CT has a 15 percent larger screening area, wrapping more than 190° around the rotor, allowing production rates to surge beyond 200 tons an hour.

Supported by a larger shaft and bearings and an optional 1200hp CAT C32, the engine powers the forged drum rotor through the toughest materials.

The design of CBI’s offset helix rotor minimizes energy loss from each strike and distributes material evenly across the 24 hammers, requiring less power.

Built from a fully welded steel frame and reinforced heavy-duty weldments, this yellow monster processes land clearing debris, pallets, clean industrial waste, stumps, logs, mulch, bark, shingles, and whole trees as fast as it can be loaded, producing valuable end-products.

Ensuring the best fuel economy and the lowest possible cost per ton, CBI’s user-friendly interface displays simplified information for controls and monitoring.

Operators can adjust and save multiple groups of feed speeds, pressures, and automated control systems to guarantee the most efficient performance across a wide range of materials.

Speed sensors have been added to the feed system for a continuous and efficient pace of grinding.


Key Features

  • Various hammer inserts
  • Replace-A-Face hammer system allows the end user to swap out the face independent of the rest of the hammer for quick, easy, and inexpensive maintenance.
  • Hog box opens in seconds
  • Increased hydraulic tank capacity
  • Wedge lock secures upper hog box
  • Sloped decks deter debris accumulation
  • Metal Detection System (MDS) protects machine from tramp metal
  • High-torque feed roller. Speed sensors monitor the feed system’s speed in real time to maintain a continuous and efficient pace of grinding
