selFrag Lab - the first commercial high-voltage pulsed power laboratory equipment for selective fragmentation

selFrag Lab: selective fragmentation with the electrodynamic high-voltage (HV) pulsed power process is now commercially available. Under a worldwide license from the Karlsruhe Research Center of Germany, selFrag AG (a division of the Ammann Group) has developed and commercialized this technology. This state-of-the-art electrodynamic process is far more efficient than any electrohydraulic method. Controlled, variable HV-discharges of very short duration are applied to solids under water. Very fine plasma channels and the resulting shock waves propagating through the solids cause the material to disaggregate along grain interfaces, inclusions or inhomogeneities. The selFrag Lab fragmentation process is highly selective as compared to mechanical crushing and milling. It liberates morphologically intact minerals while minimizing production of undesired fines.

The selFrag Lab laboratory fragmentator is a user-friendly, compact piece of equipment designed for use in a wide range of laboratory environments in the mining, oil and gas industries and also in geological surveys and at other research institutes. selFrag Lab opens up new horizons for the exploration of natural resources and in sectors such as paleontology and planetology, material analysis and process development.
