Some material doesn’t go straight into a grinder. Railroad ties with hardware still in them. Contaminated C&D full of rebar. Cable spools. Windmill blades. Stumps packed with rock. Rotochopper shredders handle the first step — breaking down the material your grinder shouldn’t see, so the rest of your operation runs the way it should.
Protect Your Grinder
Shredding contaminated material before it reaches your grinder removes metal, reduces abrasion, and keeps your downstream equipment running longer. A twin-rotor cutting system handles unpredictable material streams — clean wood one day, contaminated C&D the next — and produces consistent output either way. Integrate with a Rotochopper grinder or hammermill and you have a complete processing system in one pass.
Benefits
- Protects downstream grinding equipment
- Consistent output across mixed material streams
- Reduces cost per ton
- Electric and diesel options available
- Scales from compact facilities to high-volume mobile operations
Diesel Shredders
Track-mounted, diesel-powered, and built to follow the work. Rotochopper shredders run from 350 to 770 hp across three size classes — railroad ties, contaminated C&D, stumps, cable spools, municipal solid waste. Twin-rotor cutting systems deliver consistent output regardless of what you’re feeding them.
- Power: 350–770 hp diesel
- Three size classes: 75 / 85 / 95
- Track-mounted, fully mobile
- Best for: Railroad ties, contaminated C&D, cable spools, MSW
Sarlac
Electric-powered, compact, and built for fixed facilities. The Sarlac runs on 50–125 hp and fits where diesel machines can’t — indoors, inside a sorting line, anywhere fuel cost or exhaust is a real constraint. Minimal wear parts, quiet operation, low dust. A large feed opening handles bulk material without constant adjustment.
- Power: 50–125 hp electric (230–480 kW)
- Feed Opening: 8′ W × 7′ 3″ H
- Weight: 11,500 lbs.
- Best for: Pallets, C&D, waste management facilities
Waste Wood Fine Rotors
- Patented cutting system utilizing a combination of cutting and crushing
- Cutting action for homogeneous output
- Crushing action for fewer superfine particles
- Aggressive automatic intake supports high throughput
Waste Wood Rough Rotors
- Crushing action for coarse primary shredding of wood waste
- Undeterred by non-shreddables such as iron fittings, screws and bolts
C & D/MSW Rotors
- Signature ripper combos provides aggressive material intake in both directions
- optimized configuration for automatic self-cleaning of the cutting unit
95DK Shredder: C&D Waste
Watch as the Rotochopper 95DK Shredder pre-shreds construction and demolition waste, helping to divert from landfills. The 95DK removes metal and downsizes abrasive materials to provide a steady stream of material optimized for grinding.
