Embodiment Construction
[0059] The method can be implemented on the basis of a typical design of a cone crusher.
[0060] Any sensor known in the prior art can be used as a distance sensor, for example an ultrasonic sensor with a range from 30mm to 300mm and capable of being synchronized and programmed for joint operation. For example, the US300-30GM-IUR2-V15 sensor available from PEPPERL+FUSHC (DE). The sensor emits pulses in a periodic pattern. The pulses are reflected from object surfaces present in the "active working area" and the distance to the object to be monitored is determined by the rime of returning the pulses to the sensor. We consider an example using three measurement sensors, since the inventors believe that this variable is optimal due to the use of three points to determine the position of a plane in space.
[0061] The purpose of the "measuring plane" is the disk R, which is rigidly fixed perpendicular to the axis of rotation at the end face of the body of the plain bearing of t...

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.
Description
technical field [0001] The present invention relates to crushing and reducing devices, in particular to cone crushers, and may be used in the construction, mining and beneficiation industries. Background technique [0002] Modern crushing units are complex and expensive machines in mining. One of the most impotent problems is the possibility of tracking all operating parameters very precisely, maintaining said parameters within predetermined limits and also predicting and preventing emergency situations. When a crusher breaks down, this usually leads to an interruption of all process sequences of enterprises mining and processing ores, of which the crusher is an integral element. [0003] The design of crushers has been known for a long time and described in the literature. For example, the book "VIBRATORY CRUSHERS (vibration crusher)" of Vaisberg published by VSEGEI publishing house in St. Petersburg in 2004, L.A., etc., includes the 9th chapter "Studies ofMethods for Con...
