Welcome to the CD Lab

The Comminution Dynamics Lab, also known as the Rock n’ Roll Lab, addresses research and development issues related to ore breakage and the equipment and processes that accomplish this.

Comminution processes are integral to many human activities with mineral processing in the mining industry, pigment grinding in the paint industry, metal powder production in the automotive industry, metal hybrid fabrication through mechanical alloying in grinding mills in the hydrogen hydride sector as well as in “in-situ resource utilization” in space exploration activities.

Why “Rock n’ Roll” ?

“Rock n’ Roll” describes ofcourse a form of music. It also describes just that: a rock and a roll.

A rock is an element or a component while a roll is an interaction of a rock with another element or component.

This describes a system.

A system is a set of interactive and interdependent elements that work together to accomplish some desired goal.

This describes the object of our research: the system.

Break down the system into its elements and components, describe and model those elements and components, investigate the interactions and interdependencies and model them, simulate how they behave and contribute to accomplishing the desired goal. Validate that indeed the system behaves as simulated. Ultimately, investigate if the path to reach this desired goal can be quantified by time, energy, mass and strength and determine if it can be optimized. If so, apply it.

So, what do you get when you have many rocks and many rolls?

Yes, the Rolling Stones and It’s Only Rock n’ Roll!
