On any demolition or construction site that produces mixed debris, one machine is increasingly making the difference between debris hauled at full volume and debris compacted into smaller, more efficient loads: the slow-speed shredder. The Komplet Krokodile PLUS is the slow-speed shredder built into the Komplet America lineup, engineered for North American C&D recyclers, demolition contractors, and operators who need to reduce mixed material volume on-site without specializing into a single waste stream.
This overview walks through what the Krokodile PLUS slow-speed shredder actually is, the verified specs that matter, the materials it handles — and the materials it does not — the quick-change shaft system that lets one machine cover concrete-heavy demolition days and wood-heavy land clearing days, and how it integrates with the rest of the Komplet equipment lineup.
What a Slow-Speed Shredder Actually Is
A slow-speed shredder uses two heavy-duty rotating shafts equipped with hardened teeth that grip and tear material through high-torque shear at low rotational speed. The mechanical principle is fundamentally different from high-speed grinders, hammer mills, or chippers, which all rely on impact energy at high RPM to fracture material.
That difference matters in practice. High-speed machines throw dust, generate noise, struggle with contaminated feed (rebar, fasteners, embedded metal), and tend to consume wear parts quickly on dense material. Slow-speed shredders run quieter, throw less dust, handle contaminated and mixed feed without overheating, and shred dense material like reinforced concrete and asphalt without destroying their cutting components on the first hard chunk that comes through.
The trade-off is throughput rate. A slow-speed shredder is not the fastest machine for any single material; it’s the most reliable machine for the widest range of mixed materials in real demolition and recycling conditions.

The Quick-Change Shaft System
One of the most practical features of the Krokodile PLUS is the quick-change shaft system. Two distinct shaft and tooth configurations are available, designed to be swapped to match the day’s feed material:
C&D / Asphalt Shaft
Engineered for concrete, asphalt, brick, block, masonry, and dense rubble. This is the configuration that runs at up to 175 tph throughput and handles the heaviest demolition flow.
Wood / Lightweight Waste Shaft
Engineered for wood, drywall, plastics, mixed waste, and lighter C&D debris. This configuration runs at lower tonnage but with tooth geometry that grips fibrous and lightweight materials more efficiently than the C&D shaft.
The practical implication: a single Krokodile PLUS can support concrete-heavy demolition work as well as wood-heavy land clearing or municipal waste reduction work. Contractors do not have to buy two specialized machines — they swap shaft sets to match the feed.
What the Krokodile PLUS DOES Shred
The Krokodile PLUS is engineered for a wide range of C&D and bulky waste streams. With the right shaft set selected, it handles:
- Concrete — slabs, blocks, demolition rubble (with or without light rebar contamination, using the C&D shaft)
- Asphalt — chunks, slabs, demolition pavement (using the C&D shaft)
- Brick, block, masonry, and stone rubble (using the C&D shaft)
- Wood — framing lumber, plywood, OSB, pallets, branches, brush (using the wood/waste shaft)
- Drywall and gypsum board (using the wood/waste shaft)
- Plastics — packaging, sheeting, vinyl siding, demolition plastics (using the wood/waste shaft)
- Mattresses and bulky furniture (commercial demolition or municipal cleanouts)
- Mixed C&D debris with multiple material types in one load
- Light embedded ferrous content — fasteners, embedded nails, light rebar, banding (extracted by the integrated magnetic separator)
- Green compost feedstock and bulky organic material (using the wood/waste shaft)
- Tires and light rubber — car tired and other rubber products (using the wood/waste shaft)
What the Krokodile PLUS Does NOT Shred
The Krokodile PLUS is not a metal shredder, not a rock crusher, and not a chipper. While it tolerates light steel contamination such as short rebar, nails, and banding, it is not designed for:
- Clean steel scrap, intact pipe, structural rebar bundles, vehicle bodies, or large appliances (use a dedicated metal shredder or shear)
- Solid rock or ore material — a slow-speed shredder is not a substitute for a jaw or impact crusher on hard rock
- Hazardous waste, asbestos-containing material, or regulated waste streams (use licensed disposal pathways)
- Fine wood chip production — the Krokodile PLUS produces a coarser shred than a dedicated chipper or hammermill
Where the Krokodile PLUS shines is mixed C&D and bulky waste reduction. Where another machine type is purpose-built for a single specialized stream, that other machine usually wins on throughput for that one stream. The Krokodile PLUS wins on versatility across a wide mix.
How the Krokodile PLUS Integrates with the Komplet Lineup
On most demolition and recycling sites, the Krokodile PLUS does not work alone. It pairs naturally with the rest of the Komplet equipment lineup to form a complete on-site recycling system:
Paired with a K-JC 704 PLUS portable jaw crusher or K-JC 805 mobile jaw crusher, the Krokodile PLUS handles material that’s too bulky, mixed, or contaminated for direct crusher feed — reducing it to a manageable size for the crusher to produce final aggregate.
Paired with a Kompatto 5030 heavy-duty vibrating screener, the shredded output can be sized into multiple grades for different end uses — from coarse fill to spec-grade material.
The combination matters because most demolition sites don’t produce one clean material stream. They produce mixed everything, and the equipment that can absorb that mixed feed without bottlenecking is the equipment that pays back fastest.
Mobility, Transport, and Site Setup
The Krokodile PLUS is built around the same compact, mobile philosophy that defines the rest of the Komplet lineup. The tracked chassis allows on-site repositioning under hydraulic power; the unit transports between jobsites on a standard heavy-haul trailer without specialized permits in most U.S. jurisdictions.
Setup is fast: tracked off the trailer, deployed in minutes, ready to feed. The wireless remote control means a single operator can position the machine, adjust feed, and run the shredder while remaining outside the active machine zone — a meaningful safety improvement over older shredder designs that required cab operation or close proximity.
Operating Considerations and Best Practices
Operating any slow-speed shredder responsibly starts with three universal practices: refer to the user manual for the specific machine model, ensure operators are properly trained on the controls and emergency stops, and maintain the OEM service intervals.
Specific to the Krokodile PLUS:
- Match the shaft set to the day’s feed material. Running the wood/waste shaft on heavy concrete material accelerates wear; running the C&D shaft on light wood reduces throughput.
- Inspect shafts and teeth daily. The slow-speed approach is forgiving on contaminated feed but not invisible — wear-part inspection catches small issues before they become production-stopping ones.
- Keep the magnetic separator clear. Ferrous extraction is automatic but the collection point needs regular emptying for the system to keep working.
- Stage the feed. Slow-speed shredders work best with a steady, even feed rate — not surges of large batches followed by gaps.
- Coordinate with the loader operator. The shredder’s consistent feed rate dictates how the upstream excavator or loader cycles material into the hopper.

For customers who want a faster path to break-even, Komplet America’s pre-owned equipment inventory periodically includes returned and traded Krokodile units at meaningful savings off new pricing.
Komplet America’s equipment financing options include traditional purchase financing, lease structures, and rent-to-own paths. Customers should consult their accountant about Section 179 and bonus depreciation in conjunction with any equipment financing decision.
Frequently Asked Questions
Can the Krokodile PLUS shred concrete?
Yes. With the C&D / Asphalt shaft installed, the Krokodile PLUS shreds concrete (including reinforced concrete with light rebar contamination) at up to 175 US tons per hour under ideal conditions. Light embedded ferrous content is extracted automatically by the integrated magnetic separator on the discharge stream.
Can it shred asphalt?
Yes. With the C&D / Asphalt shaft, the Krokodile PLUS handles asphalt chunks, slabs, and demolition pavement at production rates similar to concrete. Asphalt is generally easier on the cutting components than reinforced concrete.
What’s the difference between the Krokodile and the Krokodile PLUS?
The Krokodile PLUS is the current production version of the Krokodile platform, with the latest hydraulics, control interface, emissions package, and quick-change shaft system. References to “Krokodile” without the PLUS designation refer to earlier generations no longer in current production.
Is the Krokodile PLUS a replacement for a jaw crusher?
No — it complements a jaw crusher rather than replacing it. The Krokodile PLUS reduces volume on bulky and mixed feed; a jaw crusher produces sized aggregate. On demolition sites that need both volume reduction and finished aggregate, the two machines work together.
Can one operator run the Krokodile PLUS?
Yes. The Krokodile PLUS is operated by wireless remote control, allowing a single operator to position the machine and run the shredder from outside the active machine zone. A loader or excavator operator typically feeds the hopper from upstream.
How often do shafts and teeth need replacement?
Wear-part service intervals depend heavily on the material mix being shredded — heavily contaminated or abrasive feed wears teeth faster than clean material. Operators should inspect shafts and teeth daily and follow the OEM service intervals in the operator’s manual. Komplet America stocks all Krokodile PLUS wear parts at the U.S. parts inventory.
Is the Krokodile PLUS available for rent?
Rental availability varies by dealer and region. Find your local Komplet dealer to check current rental options.
What kind of warranty comes with a new Krokodile PLUS?
Komplet America provides a standard new-machine warranty plus stocked U.S. parts inventory and a service-provider network. See the parts and support page for current warranty terms.
Final Thoughts
The Krokodile PLUS is the right answer when the job is mixed C&D debris, bulky waste reduction, or volume-reduction across multiple material streams — not when the job is a single specialized waste stream where a purpose-built machine wins on throughput. The quick-change shaft system means a single Krokodile PLUS covers the realistic mix of material that shows up on most demolition and recycling sites in North America.
