Abstract
An apparatus for crushing mine ore or hard rock primarily for initial reduction for transport of the material for further processing which is characterized by an extremely low vertical profile relative to its size and capacity. The crushing jaws which form the crushing chamber are uniquely arranged in an inclined relationship with the lower jaw mounted for eccentric movement relative to the upper jaw which is stationary to provide efficient crushing action and efficient movement of the crushed material through the chamber while also permitting the associated inlet feed apparatus to be disposed at a low attitude. Means are included to provide for varying the size of the discharge opening and for varying the action of the moveable crushing jaw to permit greater versatility in the proper processing of a given material.
Claims4
An improved low profile crushing apparatus for mine ore or hard rock comprising, in combination, a base means;
- a first crushing jaw means mounted in a releasably fixed position on said base in a vertically inclined position;
- a second crushing jaw means mounted on a support means and disposed below and spaced from said first jaw means in a similarly vertically inclined position to define a crushing chamber between said respective jaw means, said support means including a supporting toggle arrangement near its upper end mounted on said frame means;
- eccentric drive means mounted on said frame means and operatively connected to the upper and lower ends of said support means carrying said second jaw means to impart repetitive predetermined motion to said second jaw means relative to said first jaw means;
- feeding means mounted adjacent to said crushing chamber and means mounted adjacent to the lower end of said crushing chamber to collect and transport material passing through said crushing chamber.
