DEVICE FOR AUTOMATIC CONTROL OF GRINDING PROCESS Russian patent published in 2006 - IPC B02C25/00 

FIELD: mining.

SUBSTANCE: device comprises control unit, unit for control of operating cycle, power control unit, and unit for choosing criteria. The device additionally has unit for collecting information, unit for processing information, unit for generating control signal, unit for control of inactivity period by the signal from the metal locator, unit for shaping control signal, unit for generating alarm signal, signalizing unit, and temperature gauge. The outputs of the unit for collecting information are connected with the pickups of the metal locator, power pickups, and temperature gauges. The outputs of the unit for processing information are connected with the outputs of the unit for collecting information and unit for choosing criteria whose output is connected with the input of the unit for generating control signal whose first output is connected with the input of the unit for generating alarm signal, second output is connected with the motor of the conveyor through the unit for shaping the control signal and second output of the control unit, and third output is connected with the signalizing unit. The first output of the control unit is connected with the input of the unit for control of inactivity period. The input of the unit for control of inactivity periods by the signals from the metal locator is connected with the second output of the pickup of the metal locator. The outputs 1-5 of the unit for generating the signal of alarm are connected to the circuit for control of the mechanisms.

EFFECT: simplified circuit.
