Optimal Fragmentering

​Information om projektet (endast på engelska)

 

​With the growing environmental concern, as well as the increasing concern for sustainability of natural resources, the need of improving the performance and efficiency of today’s crushers is becoming increasingly important. However, the development of existing crushers requires an extended basic knowledge about the crushing process itself. The aim of the research project Optimal Fragmentation is therefore to find the theoretically optimal way of crushing compressively under given circumstances. 

What is considered as the best way of crushing varies depending on the application. In addition, conflicting interests are not seldom present resulting in rather complex problems requiring computer-assisted evaluation, i.e. optimization, in order for the solution to be found. 

The objective of the project is to construct a conceptually new crusher from what is infered by research as theoretically optimal. This is carried out through studies on how the compression ratio, different machine parameters and the geometry of the crushing chamber affect the resulting particle size distribution. 

Optimal fragmentation was at first initiated during 2005 at Chalmers University of Technology. The project was restructed into a Ph.D.-project in September 2007 as of which the project is financed by the Swedish Mineral Processing Research Association (MinFo), the Swedish government research program MinBaS, and Sandvik Mining and Construction.
