    摘要： The improved method and apparatus for shattering, comminuting or reducing the size of shock-severable solid substances or materials, such as ores, minerals and rocks, includes charging a pressure vessel, which forms a first zone, with the solid material, introducing a compressible working fluid into said vessel, and thereafter causing the solid material to be entrained in the expanding working fluid and discharging the entrained material into a second zone of lower pressure though a system wherein the entrained material is continuously subjected to shock phenomena from the time it exits from said first zone until it is discharged into said second zone. The method and apparatus also includes a dual system to impact high velocity material streams against each other to shatter and reduce the size of said solid material. The apparatus injects the working fluid in such a manner and so locates and operates a quick-opening valve so as to prevent significant wear or damage to the valve.
