Crushing systems operating regime controlling methods and devices

11:

• A method for diagnosing an operating state of an elastic lining material and analysing the parameters of a load being ground by the grinding components of ore grinding machines, carried out by integrating a measuring device into the lining material in the form of a control sensor, the method comprising:
• measuring the axisymmetric deflection of the elastic lining material under the influence of an external force;
• sending, in real time, the recorded data to the information system;
• diagnosing the operating condition of the elastic lining material to determine the wear, which includes reaching the minimal thickness;
• analysing a ground load is based on recording an impact on the surface of the lining by determining the number of ground fragments, the mass of ground fragments, and whether foreign parts are present in the mass.

• A diagnostic measuring device for diagnosing the operational mode of ore grinding machines with the grinding components comprising:
• a housing element configured for integration inside the elastic lining material;
• and
• a movable sensitive element structurally adapted due to the existing elastic pressure means to a constant stop in the direction of the abradable surface of the elastic lining material;
• wherein the movable sensitive element records the axisymmetric deflections of the elastic lining material and transmits data to the transmitting element, so that the electrical signals allow the determination of the degree of wear of the elastic lining material, the minimal thickness, and the characteristics of the impact of the load on the surface of the lining material;
• and
• wherein the signals are transmitted in real time to an external information system for subsequent analytical processing.
