Method and apparatus for measuring and adjusting the setting of a crusher
First Claim
1. A method for measuring and monitoring the setting of a crusher during the crushing process, in which method the erosion of the wearing parts of a crusher is measured and the setting of a crusher is adjusted based on the measurement result so as to maintain the setting at a predetermined value irrespective of the erosion of the wearing parts, characterized in that the measurement data indicating the amount of erosion in said wearing parts of the crusher is transmitted wirelessly to the exterior side of the crusher.

Abstract
A method and apparatus are disclosed for measuring and monitoring the setting of a crusher, in which method the erosion of the wearing parts of the crusher are monitored by sensors capable of transmitting the measurement data to the crusher'"'"'s automatic control system. Based on the received measurement data, the control system adjusts the crusher setting so as to maintain the setting at its predetermined value irrespective of the erosion of the crusher'"'"'s wearing parts. The invention also relates to alternative embodiments of wear sensors for the wearing parts of a crusher. The measurement data indicating the amount of erosion in the wearing parts is transmitted wirelessly to the exterior side of the crusher.

- 3. An apparatus for measuring and monitoring the setting of a crusher during crushing, the apparatus comprising at least one wear sensor mounted on a crusher liner, means for adjusting the crusher setting, at least one sensor mounted on said means for adjusting the crusher setting and an automatic control system of the crusher, in which apparatus said crusher'"'"'s automatic control system receives a first input signal from a wear sensor mounted on at least one liner of the crusher, said first input signal being suitable for determination of amount of erosion in said liner, and a second input signal from said sensor mounted on the setting adjustment means of the crusher, said second input signal being suitable for determination of the relative position of the support surfaces of the crusher'"'"'s wearing parts, whereby the crusher'"'"'s automatic control system is able based on both input signals to adjust the crusher setting so as to maintain the setting of the crusher in its predetermined value irrespective of the erosion of the wearing part, characterized in that at least one wear measurement sensor is mounted on each one of the crusher liners, and that said sensors are equipped with means for transmitting the measurement data wirelessly to the exterior side of the crusher.
