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.
