Abstract
A crusher device includes a crusher head positioned within a container that is fed material to be crushed by the crusher head. The body of the crusher head includes at least one aperture in which at least one of an eccentric assembly and a portion of a cylinder is positioned. The container that receives material may be defined by a substantially vertical inner wall. The inner wall may be defined by a wearable surface. The crusher head may also have a wearable surface defined by a mantle.
Claims13
A gyratory crusher comprising:
- a container having a space for receiving material to be crushed, the space of the container defined at least partially by an inner wall of the gyratory crusher;
- a crusher head positioned within the container;
- a top section provided with a spider extending between a first side of the crusher and a second side of the crusher;
- the crusher head being located within the container such that rotational or eccentric movement of the crusher head causes material located within the container to be crushed;
- and,
- a central hub of the spider being positioned adjacent to the crusher head;
- wherein the crusher head has at least one aperture defined therein, and at least one of (i) an eccentric and (ii) a piston of a cylinder is at least partially positioned within the at least one aperture of the crusher head;
- wherein the at least one aperture is comprised of a first cavity or first channel defined in a body of the crusher head, the body of the crusher head attached to a mantle such that the mantle directly engages material to crush the material;
- and
- wherein the eccentric and the cylinder are each partially positioned within the first cavity or first channel of the body of the crusher head, the piston of the cylinder is comprised of a piston member that is adjustable to a plurality of positions to adjust a vertical position of the crusher head within the container.
