Abstract

PURPOSE: To widen a service temp. range at the time of crushing by reacting static crushing agents essentially consisting of CaO or the like with water in the presence of NaCl, in a method for statically crushing brittle objects, such as rocks, by using these crushing agents. CONSTITUTION: Moldings obtd. by mixing CaO, alumina cement, boric acid and NaCl, then subjecting the mixture to pressure molding are disintegrated. The brittle objects are crushed together with the water at about 5 to 30 deg.C by using the resulted granular materials. At this time, the coexistence ratio of the crushing agents and the NaCl is adequately 0.1 to 5 pts.wt. NaCl per 100 pts.wt. crushing agents. Then, the service temp. range at the time of crushing may be made wider than heretofore. The crushing agents are, therefore, made easier to use and simultaneously a delay effect may be expected as well.
