KARINE: sensing device to calculate online wear of crushing parts

This device is intended to reconstruct the degree of wear of crushing components. The wear sensor, named KARINE, uses mathematical models characterizing the wear of the crusher on the basis of measurable values (power, output flow). These measurements are processed by a state reconstructor (Kalman filter). The resulting sensor provides information on the wear drift around the operating set point. If the wear drift exceeds a given threshold, the operator adjusts the opening of the crusher. A new operating set point is then defined and the wear drift is reinitialized.
