After finishing his bachelor (UBC, Mech. Eng., 1983), Peter Radziszewski and an Iranian friend left to discover Quebec through a summer French language program (Explore) in Chicoutimi. After a couple of years in the "Royaume du Saguenay", he was off to Université Laval to complete a Masters (1986, génie mécanique) followed by a doctorate (1992, génie mécanique) both in the field of modelling, simulation and automation of ball mill grinding under the supervision of Professeur Tarasiewicz. The end of his studies found him at the Université du Québec en Abitibi-Témiscamingue (1991-2000) as professeur régulier in the Applied Science Department where as Department chair (1992-1997) he worked to develop a full engineering program that caters to the needs of regional industry. His research work, which has taken him to the JKMRC for a sabbatical in 1997-98, is on grinding mill modelling, identification and optimisation as a function of the non-stationnarities caused by mill wear (abrasive, corrosive or impact). As of January 2001, he has joined the Department of Mechanical Engineering at McGill University as an Associate Professor in engineering design and pursues research interests in comminution and design.
Since coming to McGill, he has been involved in research projects mainly related to the mining industry totaling about 28 million dollars with the major ones being AMIRA/JKMRC P9M (~ 7 000 000 $CAN), P9N ((~ 8 000 000 $) and Canadian Space Agency/Neptec Lunar Exploration Light Rover (11.5 million $). His contributions in the AMIRA P9 projects led to the development of a steel media wear prediction methodology that has been licensed to JKTech. Work with COREM has led to bringing real-time charge motion simulation and prediction closer to the mill operators. He has been recognized as one of the two initiators of the use of discrete element methods in modelling of tumbling mill charge dynamics and his “outstanding contributions toward the development of Autogenous and Semiautogenous Grinding technology” has been acknowledged at the SAG2006 conference. His teaching activities in engineering design have led to the development of an electric snowmobile, a hybrid race car, contributions to powertrain modelling and simulation as well as the development of a prototype wheel for lunar mobility inspired by tumbling mill charge motion. He is the author/co-author of over 100 paper and conference proceedings, one book, four book chapters, 1 patent (wear sensor) and 3 patent pending (instrumented ball, microwave assisted drill, particulate filled metal fabric wheel).
Comminution processes: dynamics, wear, breakage, design, instrumentation & optimization, mobility and traction
Since spending a sabbatical stay at the Canadian Space Agency (CSA), we were able to define and develop a project on traction systems for lunar mobilty in partnership with the CSA and Neptec Design Group. The goal of this project is to explore, investigate and develop a design methodology for lunar traction (wheel) development. This project addresses different dimensions of lunar mobility such as wheel design, wear, reliability and electric motor design. One of the wheel designs dubbed iRings (short for Iron Rings in reference to the rings of the chainmail used and the engineering Iron Ring) has attracted some attention as illustrated by the following stories in the media.

The idea of developing a silent snowmobile was first proposed while at the Universite du Quebec en Abitibi-Temiscamingue. However, this idea did not take root there. In coming to McGill as a professor in engineering design, the idea was again proposed but this time in the frame of the MECH463 Mechanical Engineering project course in the fall of 2001. A first group of students took on the project and then another group in the spring of 2002. This group of students were successfull in have a first version travel a few tens of meters down the McConnell building hallway. The Fall of 2002 saw a subsequent group of students take on this project where one of these students (Simon Ouellette) continued on to create a team and lead this design effort since then. Over this time a number of stories about this snowomobile has found themselves in the media.
