The invention relates to crushing and reducing device, in particular to cone crushers, and can be used in the building and ore-dressing industries. The inventive method is carried out by means of a crusher which is provided with proximity sensors, the operation of which is controlled by means of a computer, and with a disc R which is rigidly secured to the unbalanced-mass vibration generator of the crusher in such a way that the plane thereof is always perpendicular to the axis of rotation of the unbalanced-mass vibration generator. Said method consists in measuring a distance to the disc R, in calculating the three-dimensional position of the disc plane, in calculating the amplitude of the circular vibrations of the internal cone according to said position, in calculating the size of a crushing gap according to the thus calculated amplitude, in comparing said size with the specified parameter of the gap by means of a computer and, if, according to the comparison results, the adjustment of parameters M is required, in transferring a control instruction for modifying the position of an adjustment ring from the computer to hydraulic cylinders. The adjustment ring position is controlled by means of a proximity sensor which is mounted on the flange of a body top part. The inventive method makes it possible to measure and modify the main process parameters directly affecting the quality and performance of the machine operation during the continuous operating mode thereof, to prevent malfunctions and emergency situations with a high degree of probability and to carry out the fullest monitoring of the crusher state at any time, thereby making it possible to efficiently use and to extend the service life of the working surfaces and to apply a totally computerised control by excluding a human factor. |
