3.3" x 5" IRM #3350, 2-Hi Laboratory Rolling Mill, satin, High Carbon Chromium Alloy Steel, 3 HP AC motor, 220 Volt, 3PH

The IRM 3350 2-High Laboratory Rolling Mill is a mid-scale laboratory rolling mill designed to support both instructional use and applied research, offering greater capacity and rigidity than compact bench-top units while maintaining a footprint suitable for laboratory and R&D environment. The IRM 3350 is positioned between compact bench-top rolling mills and larger, higher-capacity laboratory or production rolling systems.
The mill is driven by an AC motor with variable speed control, transmitting power through a mechanical drivetrain with integrated reduction gearing. This configuration provides controlled rolling speeds, stable low-RPM operation, and predictable torque deliverysupporting both hands-on instruction in rolling fundamentals and more demanding experimental rolling work.
Compared to smaller laboratory mills, the IRM 3350 features a larger frame, increased roll capacity, and a more robust roll train, offering improved stiffness and reduced deflection under load. These characteristics support consistent thickness control, repeatable results, and meaningful process evaluation across multiple rolling passes.
