Abstract

A cone crusher characterized by a frame having a completely fabricated construction, an anti-spin mechanism and an improved crusher setting indicator is disclosed. The frame of the structure, which is composed solely of pre-formed and/or forged members, includes a number of tubular members, a number of annular members and a number of ribs, all of which are welded together to provide a rigid, strong frame. The anti-spin mechanism is characterized by the use of a unidirectional valve and a spring loaded ball valve, thereby permitting the rotation of the mantle of the crusher in one direction while barring rotation of the mantle in the opposite direction unless a force exceeding a pre-selected magnitude is applied to the mantle. The crusher setting indicator, which is used to determine the distance between the moveable mantle and the stationary concave of the crusher includes a rod supported by the crusher, the rod abutting the cone support bearing seat of the crusher, the position of which seat is directly related to the position of the mantle. A pinion gear is coupled to the rod and the orientation of the gear is used to provide an indication of the distance between the mantle and concave.

Claims

1. A crusher setting indicator for a cone crusher, which crusher includes a movable mantle and a stationary concave, comprising:

a rod, supported by said crusher, arranged for linear movement along a line, the position of said rod along said line of linear movement being directly related to the position of said mantle along said line;

said crusher further including a center hub having an axially extending path formed therein, said rod being positioned within said path wherein said path is a crusher lubrication path and said rod is tubular, said rod thereby being adapted to form a portion of said lubrication path;

said crusher further including a cone support bearing seat arranged for movement along said line wherein one end of said rod is in abutting relationship with said seat;

biasing means coupled to said rod for biasing said rod into said abutting relationship with said seat; and

means responsive to the position of said rod along said line for providing an indication of the distance, along said line, between said mantle and said concave.

2. A crusher setting indicator according to claim 1 wherein said biasing means comprises a piston ring.

3. A crusher setting indicator according to claim 1 wherein said rod bears a plurality of teeth along at least a portion of the length thereof and wherein said responsive means is a gear arranged for rotation about a shaft, at least a portion of the periphery of said gear bearing a plurality of teeth, said gear teeth and said rod teeth being positioned for engagement with one another.
