ABSTRACT:
Rocks are known to contain minute cracks and fissures and such rocks can be crushed under less force than the ordinary crushing force when a vibrational force is applied to exert tension at the cracks and fissures. Rock crushers of the type which include hydraulic means connected to a crushing member are improved by adding means for superposing a vibratory force into hydraulic circuits of such crushers.
