Abstract: A conical crusher, comprising: an upper housing; a tubular axle lodging a supporting rod. Inside the upper housing is mounted a cone head being axially journalled onto a spherical bearing carried by an upper end of the supporting rod and said cone head being radially and eccentrically journalled around the tubular axle. The supporting rod has a lower end thereof fixed to a piston of a hydraulic cylinder in order to operate as a support means for the cone head and also as an actuator to vertically displace the cone head and adjust the opening of the crushing cavity and also as a protecting means, reducing the hydraulic pressure to prevent overloads. The proposed solution further provides a locking hub mechanism in the cone head.

Abstract: A structural arrangement for vibrating equipments of the type comprising: a pair of lateral plates (10) seated on elastic support means (30); crossbeams (11) defining at least one level of support floor (15); a screen (12) for classifying bulk product and which is secured on a respective support floor (15); and at least two vibrating devices (20) which are driven to make the equipment vibrate. According to the invention, the structural arrangement comprises at least one intermediate longitudinal plate (40) extended along the length of the equipment, between the two lateral plates (10); and at least two coplanar assemblies of crossbeams (11) defining a respective support floor (15), the crossbeams (11) of each assembly presenting an internal end (11a) rigidly affixed to the intermediate longitudinal plate (40) and an external end (11b) rigidly affixed to the adjacent lateral plate (10), each assembly of crossbeams (11) securing a screen (12) thereon.
