If you need a uniform fraction in a single pass, a four-shaft shredder with integrated screen is the solution. The four rotors, driven by two motors with differential speeds, process bulky materials, and the bottom screen holds back oversized pieces until they reach the set particle size.
The machine combines the throughput of a twin-shaft shredder with the precision of a granulator, in a compact assembly. It is suited to pallets, wood waste and other bulky materials. See the full range of recycling equipment.
• Uniform fraction in a single pass, the integrated screen internally recirculates oversized pieces.
• Four rotors, two motors, the differential speeds reduce the risk of jamming.
• Large feed opening, accepts bulky materials without prior preparation.
• Sliding screen, the particle size is changed quickly.
• Compact footprint, shredding and calibration are integrated.
• Low dust and noise, operation at low speed and high torque.
• Individually removable blades, segment-by-segment replacement.
• Automatic reversal, fast recovery on overload.

The shredder is chosen when the output must have a controlled particle size for particle board, MDF, pellets, briquettes or cogeneration. The integrated screen delivers the calibrated fraction without an external screening machine.
Compared with a shredder followed by an external screen, it reduces the number of machines, the space occupied and the complexity of the installation. For integration into a complete flow, see the full industry solutions.
Besides wood, suitable configurations can process hard plastic, rubber and other bulky materials, without these changing the main category of this product.
| Accepted material | Notes |

| Pallets and wood waste | Including with minor metal impurities |
| MDF, particle board and plywood | Wood-based composite materials |
| Hard plastic | With the appropriate screen and blades |
| Rubber and mixed waste | With an adapted configuration |
1. The bulky material is fed into the wide opening.
2. The two pairs of rotors progressively shear the material.
3. The pieces below the set particle size pass through the screen.
4. Oversized pieces are processed again inside.
5. On overload, the rotors automatically reverse direction.
6. The sliding screen is changed laterally for a different particle size.
Why four shafts instead of two?
Four rotors with differential speeds reduce jamming, and the integrated screen calibrates the output in a single pass.
What particle size does it produce?
The particle size is determined by the openings of the installed sliding screen.
Can it process materials other than wood?
Yes, with the appropriate screen and blades it can also process hard plastic, rubber or mixed materials.
How is the screen changed?
The screen is pulled out laterally, without disassembling the rotors.

„We do stainless-steel metal fabrication dedicated to restaurant kitchens. The UZINEX equipment was a radical change: modernization, an increase in production and quality.”
„I had no idea, I was completely clueless. And you started to explain to me. You told me what technologies to choose, what packaging to produce, what would work better on the market.”
„We use a single person who can operate 3-4 machines. Before, we needed 3-4 people to do the same thing.”
„We have multiple challenges in making special structures that serve our systems, and the laser welding machine solution helped us enormously.”
„Laser welding on stainless is something else, it's a completely different thing. The quality of the machines is undeniable: the samples say it all.”
„With Uzinex, I felt very well protected by the assistance they provided. When you have a whole shift stalled and you need someone to answer quickly, it matters enormously.”
„The proof that everything went well is that the equipment now works. We have over three years of experience with no problems. Or when there were issues, there was support. We're satisfied with the collaboration.”
„I can do even 5 boxes for one person, I can also do 10 boxes. Which other firms can't do. That is, they'd have to change dies, set up a whole 12-hour affair.”
„Whether I called at 2 in the morning or at 9 in the morning, the problems got solved. We're satisfied and we'll work together again.”
„A good, smooth collaboration. We always had support and help.”
„We're among the top producers in Romania for this product. I wouldn't have imagined that when I started, but things fell into place.”
„On price and quality ratio, they were the best price and the best quality on the market. We got along well and we're satisfied.”
Six technology directions we integrate turnkey: from plug & play IIoT sensors, to cobots, predictive maintenance, optical inspection, MES connectivity and custom industrial software.
See in real time how much each machine produces and how long it sits idle. We fit sensors on any equipment, new or old, and within a few hours you have the OEE dashboard on your phone. No complex wiring, no production downtime. The first concrete step toward digitalization, with ROI visible from the very first month.
Solve your labor shortage without tripling your costs. The cobot works safely alongside your people (palletizing, feeding the CNC, welding) while you recover the investment in 12-18 months. Prices 30-40% below European distributors, with installation and programming included from us.
Stop waiting for things to break. Our algorithms analyze sensor data and tell you exactly which part will fail and when, and we bring it to your production line before the breakdown. Zero unplanned downtime, zero contractual penalties, complete operational peace of mind.
Eliminate defects before they reach the customer. Our cameras inspect every part at speeds no operator can match, detecting sub-millimeter defects. They mount onto your existing line, with no modifications. Ideal if you produce for export and have strict quality clauses.
Connect your machines to your office, regardless of brand or age. Our gateway automatically translates the data from any machine into your ERP's format: no manual entry, no paper forms, no human error. The manager sees production live, the operator receives digital instructions.
Have a process that no off-the-shelf software can solve? We build custom industrial applications: from tailored SCADA panels and HMI interfaces, to production planning systems, lot traceability and automated reporting. The code is yours, it runs on your servers, with no monthly subscriptions or vendor lock-in.
