Abstract: A gyratory crusher and system for determining a close-side setting or an open-side setting is provided including a point cloud generator mounted proximate the crusher; a drone; a laser emitter mounted on the drone to mark the first trace on the mantle at a predetermined position of the gap; a camera mounted on the drone to capture a series of image of the first trace as the mantle of the gyratory crusher rotates; and a computer in communication with the camera, the point cloud generator and the drone, the computer comprising a memory and a processor, the memory providing instructions to process the image to provide a gap width and to determine at least one of a close-side setting or an open-side setting from the gap width.

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.
