The use of electrical discharges to break material can be traced back to 60 years ago.

The technology never passed the laboratory scale prototype before significant resources were invested by SELFRAG. The company originated from the Technology Centre of the Ammann Group.

The search for a further shift in development led to the evaluation of high-voltage pulsed power technology for various applications and, consequentially, to the acquisition of the expertise required to build plant installations.

SELFRAG technology is the most relevant alternative to conventional crushing and grinding techniques, and presents huge potential to reduce energy consumption and develop the new generation of sustainable and economically profitable mineral processing plants.
