A method of controlling the crushing of material in an inertia cone crusher includes the step of charging material to be crushed from a feeding hopper to a crushing chamber formed between an inner crushing shell being supported on a crushing head, and an outer crushing shell of the inertia cone crusher. An unbalance bushing, which is provided with an unbalance weight and rotatably connected to the crushing head by a drive shaft, is rotated such that a central axis of the crushing head gyrates about a gyration axis. The number of revolutions of the unbalance bushing is sensed using an rpm sensor. The number of revolutions of the unbalance bushing is controlled by a control system and the material is crushed in the crushing chamber.

Method of controlling an inertia cone crusher

A cone crusher includes an outer crushing shell and an inner crushing shell forming a crushing gap there between. The outer crushing shell is supported on an upper frame member in vertically adjustable engagement with a lower frame member. A sensor arrangement having a sensor element is provided for measuring the vertical position of the outer crushing shell. The cone crusher further includes a target means arranged to be detectable by the sensor element, wherein one of the target means and the sensor element are arranged to follow vertical movement of the upper frame member and to move in relation to the other one of the target means and the sensor element. The sensor element includes a vertical sensing array which extends in a vertical direction along at least a portion of a range within which the target means may be moved upon adjusting the vertical position of the upper frame member.
