FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to devices for grinding mineral raw materials by means of their magnetic-pulse treatment and can be used, for example, in mining industry. Device for performing magnetic-pulse treatment of mineral raw material comprises a structural element in the form of a thin-wall shell made of dielectric, non-magnetic, wear-resistant material separating inner surface of electromagnetic system and moving mineral raw material. Shell additionally comprises a low-current inductor system having inductive coupling with the main and additional inductors. Low-current inductor system serves as a sensor for measuring the rate of change of pulsed magnetic fields generated by the main and additional inductors. Low-current inductor system is connected to a measuring element which is part of the device performing measurement of amplitude-time parameters of the induced EMF in the low-current inductor system.
EFFECT: device is characterized by long service life.
