SELFRAG in a nutshell
A new way to break rocks, slags and scrap
 SELFRAG History: Swiss company, founded in
2007. Owned by PE firms, management, and
institutional/private investors
 Principles of Technology: Patented high voltage
pulse power technology that fragments or
weakens virtually any material. Proven in lab
environments and solar silicon manufacturing
(continuous 1 ton/h)
 Target Market: Continuous 100-1000 ton/h,
scalable pre-weakening system for mining and
recycling comminution circuits, both greenfield
and retrofit. Solution under development
 Value Proposition: Significant reduction in
comminution, in particular milling, energy
consumption and operational costs and
increasing efficiency and productivity

HV pulse power technology
 Based on a HV physical specificity
 At short pulse rise time water isolates more than solids
 Discharge occurs through solid, causing strong internal
shockwaves resulting in selective breakage
