TwinLabShaft TWS – Dual-Shaft Laboratory Shredder for Recycling R&D

The TwinLabShaft TWS is a dual-shaft shredding device developed by StokkermillLab for research, materials testing, and process validation in recycling and size reduction applications.

Specifically designed for research and development labs and innovation centers, the TwinLabShaft TWS enables controlled, repeatable shredding tests on a wide variety of materials, providing reliable data to support development, optimization, and scaling of industrial recycling processes.

R&D-Oriented Design Concept

The system operates with counter-rotating, low-speed, high-torque shafts, offering precise control over the mechanical stress applied to materials. This configuration:

• Minimizes dust generation
• Reduces thermal stress
• Preserves material characteristics

These factors are critical for laboratory-scale experiments and comparative testing.

A key feature of the TwinLabShaft TWS is its fully customizable cutting configuration. Blade geometry, thickness, cutting profile, and arrangement can be tailored to the specific material and application, making the device a flexible experimental platform rather than a fixed-configuration shredder.

This design approach allows researchers and engineers to:

• Compare different cutting solutions
• Simulate industrial shredding conditions
• Optimize blade design before scaling to industrial operations

‍

Industrial Correlation and Process Validation

The TwinLabShaft TWS is engineered to ensure direct correlation between lab tests and industrial-scale systems. Results obtained using the device can be used to:

• Define optimal blade geometry
• Validate process parameters
• Reduce technical risks during industrial scale-up
• Accelerate innovation cycles

Its compact footprint and industrial-grade construction make it suitable for continuous laboratory use, R&D centers, technical departments, and academic research environments.
