JUNE/JULY 2013


Graphite

................................................................................................................

SELFRAG has conducted successful tests on pilot plants for graphite processing with high voltage pulse power equipment:
The process provides a coarse fragmentation with a suitable reduction ratio to achieve liberation from feed size to -3, 2 or 1 mm. Liberation is sufficient to recover the coarsest graphite flakes and the undersized amount is limited. This simplifies the flow sheet (replacing the cone crusher, SAG and/or Rod mills and regrinding steps ) as the process prevents overgrinding and can be combined with the separation (floatation/countercurrent classification). Much of the material -2 mm could easily be separated out from the gangue by either flotation or leaching without additional grinding, increasing throughput, saving energy and ultimately reducing costs.

Behind the Scenes
..............................................................................................................

A long career and a big Thank You!
With the retirement of Harald Giese, one of the leading inventors and researchers of the SELFRAG high voltage pulse power technology has left our team. We would like to thank Harald for his outstanding contribution in making our technology successful!

 

New CTO
..............................................................................................................

We are proud to announce that Mr. Johannes Käppeler has joined the SELFRAG Team as new CTO and successor to Dr. Fabrice Monti di Sopra. After holding the CTO position for several years, Dr. Monti di Sopra has now taken a leading role in SELFRAG's board of directors. Mr. Käppeler brings exceptional know-how and experience in the field of heavy machinery construction and engineering into our team, as well as long term leadership experience in fast growing high-tech companies. He holds a master degree in mechanical engineering (Dipl. Ing.) from the Technical University Aachen. The management and team welcome Johannes Käppeler!
