Abstract (en)
Particulate solids (26) such as minerals comprising chemically or physically bound components of different hardnesses are to be broken down into smaller particles by means of shock frequency methods (25). The particles travel at high velocities and undergo inertia changes to cause the breakup. An apparatus for carrying out the method is also provided.
