Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.
A cone crusher includes a stationary main shaft and an eccentric that rotates about the main shaft to cause gyrational movement of a head assembly to crush rock within a crushing gap. The cone crusher includes a counterweight assembly mounted for rotation with the eccentric. The counterweight assembly includes a counterweight body having a series of tanks. Each tank can receive either a first ballast and a second ballast or a combination thereof. The first ballast is formed from a material having higher density than the second ballast to increase the concentration of weighting in desired locations around the counterweight assembly.
B02C 15/10 - Mills with balls or rollers centrifugally forced against the inner surface of a ring, the balls or rollers of which are driven by other means than a centrally-arranged member
B02C 17/08 - Disintegrating by tumbling mills, i.e. mills having a container charged with the material to be disintegrated with or without special disintegrating members such as pebbles or balls with unperforated container with containers performing a planetary movement
The anti-spin system is applied to a cone crusher having a structure (10) carrying an upper housing (20) and a vertical axle (30); an eccentric element (40) to be rotated around the vertical axle (30); and a cone head (60) disposed inside the upper housing (20) and being axially and rotatively supported on the structure (10) and radially supported around the eccentric element (40). The anti-spin system comprises a braking bush (70) carried by the cone head (60) or by the structure (10), and an annular shoe (80) carried by the other of said parts, which are pressed against each other, by action of the inertial centrifugal force acting on the cone head (60), upon “no-load” operation of the crusher, to generate a friction force opposite and superior to that generated between the cone head (60) and the eccentric element (40) and to prevent the latter from rotatively dragging the cone head (60).
A spider for use with a gyratory crusher. The spider includes spider arms each formed from two spaced flanges joined by a connecting web to define an open channel having an open top end. The configuration of the spider arms increases manufacturability and provides the required strength and rigidity for the spider. The channel formed in each spider arm is covered by a spider arm shield to reduce abrasive wear to the spider arm.

A bearing arrangement for a roller crusher having a pair of crushing rollers (R), each one including a shaft having end portions, mounted in respective bearing housings carried on a base structure (S) of the crusher, and a median hub portion. The bearing housings of each roller (R) are affixed to a structural frame disposed externally to each roller (R), along one side of the respective roller (R), the structural frame maintaining the bearing housings of each roller (R) rigidly connected to each other. Each bearing housing includes: a base portion affixed to the structural frame and a cover portion turned to the other roller (R) and removably affixed to the base portion.

B02C 2/02 - Crushing or disintegrating by gyratory or cone crushers eccentrically moved
B02C 23/00 - Auxiliary methods or auxiliary devices or accessories specially adapted for crushing or disintegrating not provided for in groups or not specially adapted to apparatus covered by one only of groups
A cone crusher includes a stationary main shaft and an eccentric that rotates about the main shaft to cause gyrational movement of a head assembly to crush rock within a crushing gap. The cone crusher includes a lower head bushing in contact with an outer surface of the eccentric. The eccentric is formed with a contact pad to enhance the contact between the eccentric and the lower head bushing during a no-load condition. The contact pad includes a contact surface that is recessed from the outer surface of the eccentric to enhance contact during no-load conditions while maintaining full contact between the lower head bushing and the eccentric outer surface during full load, crushing conditions.

A stress monitoring system for use in a vibrating unit having first and second opposed sidewall plates includes at least one motion sensor disposed at at least one corresponding monitoring point on each of the first and second plates. The motion sensors are connected to a processor such that simultaneous monitoring data of the monitoring points is provided to the processor for comparing real-time movement of the corresponding monitoring points of the opposed plates.
An apparatus includes a shell connection mechanism configured to be actuated between a connected state in which a mechanism is connected to a shell and a disconnected state and an actuator configured to move the first mechanism while the first mechanism is in the connected state to move the shell.
