DISCHARGE CRUSHING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a low cost discharge crushing method which enables a crushing object such as a boulder stone to be surely crushed. SOLUTION: The discharge crushing method which enables the crushing object to be crushed by electric discharge generated by supplying energy to an electrode has a preparation process (S10) for finding an energy value that can crush a sample of the crushing object by the electric discharge, a process (S20) where, under the assumption that a certain relational expression exists between sample volume and the energy value, a coefficient of the relational expression is determined, and a process (S30) where a crushing condition of the crushing object is determined based on the relational expression in which the coefficient is determined.
