Abstract

A system for monitoring at least one motion parameter of the main shaft of a gyratory or cone crusher. The system includes a sensor, such as a magnetometer, positioned within close proximity to a magnetic element, such as a lifting lug, formed on a top end of the main shaft. When the main shaft rotates or moves vertically, the movement creates a change in the magnetic flux, which is sensed by the magnetometer. The change in the magnetic flux is sensed by the magnetometer and an output signal is generated. A controller receives the output signal and determines at least one motion parameter based upon the detected changes in the magnetic flux. In one embodiment, a permanent magnet can be the magnetic element or can be inserted into the lifting lug to enhance the magnetic flux changes caused by the rotational movement or vertical movement of the main shaft.

Abstract

A system and method for controlling the operation of a gyratory rock crusher is shown and described. The gyratory rock crusher includes a variable frequency drive that allows the eccentric speed of the gyratory crusher to be modified based upon sensed parameters of the rock crushing system. The speed of the eccentric rotation can be dynamically adjusted to compensate for the size of the material particles being crushed and the availability of the material. The use of the variable frequency drive increases the operating efficiency of the gyratory crusher by controlling the discharge flow rate of the crushed material from the crusher and thus allows for a reduction in the size of the discharge hopper. The rotational speed of the eccentric is controlled to be below the critical speed for the gyratory crusher.

Abstract

A counterweight for use in a cone crusher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crusher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wall and splash shield define an inner oil chamber while an outer oil chamber is defined by the splash shield, the vertical separating wall and an inner wall of the counterweight. Both the inner and outer oil chambers include drain holes that allow lubricating oil to pass through a generally horizontal floor of the counterweight. The combination of the inner and outer oil chambers allows oil to quickly exit the counterweight into the main oil sump and reduces the amount of oil that gets exposed to the upper seal assembly which reduces the passage of oil past seal assemblies formed in the cone crusher.

Abstract

A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. 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.

Abstract

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).
