<p>A conical crusher, comprising: an upper housing (20); a tubular axle (30) lodging a supporting rod (40). Inside the upper housing (20) is mounted a cone head (70) being axially journalled onto a spherical bearing (50) carried by an upper end (41) of the supporting rod (40) and said cone head (70) being radially and eccentrically journalled around the tubular axle (30). The supporting rod (40) has a lower end (42) thereof fixed to a piston (60) of a hydraulic cylinder (11) in order to operate as a support means for the cone head (70) and also as an actuator (A) to vertically displace the cone head (70) and adjust the opening of the crushing cavity (CB) and also as a protecting means, reducing the hydraulic pressure to prevent overloads. The proposed solution further provides a locking hub mechanism (100) in the cone head (70).</p> |
