Why Buy a Bandit Horizontal Grinder?
Bandit introduced its first horizontal grinder, the Model 3680, in 1995. Since then, multiple models have been engineered and manufactured, featuring a unique cutter mill for processing diverse materials. Expanding the horizontal grinder line, in 2024, Bandit introduced its first hammermill grinder, further enhancing Bandit’s already expansive line of horizontal grinders.
Bandit Horizontal Grinders – Grinding Methods Explained
1. “CUT IT” – Cutter Mill (Beast Models)
The cutter mill is the signature grinding method used in Bandit’s Beast horizontal grinders.
How it works:
- Cutter bodies with teeth slice material apart.
- A raker tooth limits cutting depth to ~¾ inch.
- Material is sized during the first cut and quickly exits through the screen.
Advantages:
- Smooth cutting action → less vibration
- Reduced machine wear
- Less dependence on the screen and discharge gate
- Many tooth types available for different materials
- Optional fan-style tooth pushes material through the screen to increase production
Best for:
- Wood waste
- Trees and logs
- Pallets
- Stumps
- Mulch production
- Biomass
2. “CHIP IT” – Chipper Knife Setup
Some Beast grinders can be configured to act more like a wood chipper.
Two chip options:
Small chips (~¼ inch)
- Knife-style cutter bodies with small knives
- Ideal for fine chips
Larger chips (⅝ – 2 inches)
- Dedicated 4-knife or 8-knife chipper drum
