PCT No. PCT/JP96/00392 Sec. 371 Date Oct. 20, 1997 Sec. 102(e) Date Oct. 20, 1997 PCT Filed Feb. 21, 1996 PCT Pub. No. WO96/26010 PCT Pub. Date Aug. 29, 1996A method of crushing or smashing nonconductive materials such as natural ore materials and concretes by a discharge voltage requires a large amount of energy for crushing or smashing. Products produced by crushing or smashing have not been recycled effectively as new nonconductive raw materials. A value set by the quality and a thickness of the nonconductive materials to be crushed, an impulse voltage Uo, a time constant tau and a spark constant A is defined as a parameter P of an electric circuit. By setting the value of P to 0.02</=P</=1.0 to cause crushing, energy stored in the circuit can be utilized effectively. Accordingly, uniformcrushedor smashed matter with high quality can be manufactured effectively.
