Apparatus for pulverizing solid materials

Claim 1

APPARATUS FOR DISINTEGRATING A WALL OF SOLID MATERIAL FORMED OF DISCRETE PARTICLES COMPRISING A SUPPORT ROTATABLY MOUNTING A BREAKER HEAD ON A FIRST AXIS WHICH, WHEN THE APPARATUS IS OPERABLE IS PARALLEL TO THE SURFACE OF SAID WALL, AT LEAST ONE BREAKER ELEMENT ROTATABLY SUPPORTED ON SAID HEAD ON A SECOND AXIS DISPOSED IN PARALLEL SPACED RELATION TO SAID FIRST AXIS, MEANS FOR ROTATING SAID BREAKER HEAD IN ONE DIRECTION ABOUT SAID FIRST AXIS EFFECTIVE TO CARRY A PERIPHERAL POINT OF SAID BREAKER ELEMENT FOR ENGAGEMENT WITH SAID WALL, MEANS FOR ROTATING SAID BREAKER ELEMENT ABOUT SAID SECOND AXIS IN A DIRECTION OPPOSITE TO THE DIRECTION OF ROTATION OF SAID HEAD, MEANS FOR SYNCHRONIZING THE ROTATION OF SAID BREAKER HEAD WITH SAID BREAKER ELEMENT SO THAT AT THE INSTANT THE PERIPHERAL POINT ON SAID BREAKER ELEMENT IS CARRIED INTO ENGAGEMENT WITH SAID WALL OF MATERIAL THE LINEAR VELOCITY OF SAID PERIPHERAL POINT DUE TO THE ROTATION OF SAID BREAKER ELEMENT IS SUBSTANTIALLY EQUAL AND OPPOSITE TO THE LINEAR VELOCITY OF SAID POINT DUE TO THE ROTATION OF SAID BREAKER HEAD, AND SAID PERIPHERAL POINT AT THE INSTANT OF CONTACT WITH SAID WALL BEING OPERABLE TO TRANSMIT THE FORCE GENERATED BY THE ROTATION OF SAID BREAKER HEAD SUBSTANTIALLY COMPRESSIVELY AGAINST SAID WALL AND PERPENDICULARLY AGAINST THE SURFACE THEREOF UNDERLYING SAID POINT.
