CBI®’s offset helix rotor and split hog box - engineered to lead, built to last.
Before imitators even knew what to copy, CBI had already spent decades perfecting it. With decades of grinding innovation behind us, the patented offset helix rotor remains at the core of the industry’s most productive machines - not just holding up in the field but dominating it.
CBI didn’t just build grinders - we engineered a better way to grind. The offset helix rotor, a product of years of innovation and field refinement, set a new standard for what industrial horizontal grinders could do. With years of proven success in forestry, land clearing, and biomass applications, CBI’s rotor design isn’t just an upgrade - it’s a benchmark.
At the center of every CBI grinder is our patented offset helix rotor - a design that’s earned its reputation through relentless performance and efficiency. Unlike traditional straight or staggered rotor setups, the offset helix delivers a continual diagonal striking sequence, maximizing the power of every impact while minimizing energy loss.
This unique configuration requires less power to rotate, increasing fuel efficiency without sacrificing throughput. As material is washed diagonally across the rotor, wear is distributed evenly - extending the life of internal components and keeping machines running stronger, longer.
Rotor Performance Advantages:
- Continual diagonal striking sequence for aggressive, efficient grindin
- Lower power demand, higher productivity
- Material flow washes across rotor to reduce concentrated wear
- Delivers cleaner, more consistent sizing
- Offset helix design delivers full power with every strike, maximizing impact efficiency.
The Original Advantage
- Some grinders may attempt to imitate the look of a CBI, but they can’t replicate the performance, durability, or innovation that’s been built into every machine we’ve ever made.
- Competitors often mimic the design - but without the engineering backbone and field-tested evolution behind our rotor, they simply fall short when it matters most.
- Performance isn’t a matter of marketing - it’s measured in uptime, output, and results. And that’s where CBI stands alone.
