System and method for measuring a closed-side and/or open-side setting of a gyratory crusher

Abstract

An improved gyratory crusher is provided. The gyratory crusher comprises an eccentrically rotating mantle lined with a mantle liner, a concave lined with a concave liner, the concave housing the mantle to provide a crusher chamber, and the crusher chamber having a gap. The improvement is a system for determining a close-side setting for the gyratory crusher based on the gap width. The system includes a cross hair laser emitting a first trace and a second trace, the laser mounted to mark the first trace on the mantle liner and to mark a second trace traversing the gap and at least intersecting the concave liner at a preselected position of the gap, a camera mounted to capture an image of the first and second trace, and a computer in communication with the camera, the computer comprising a memory and a processor, the memory providing instructions to the processor to process the image to provide a gap width and to calculate a close-side setting.
