Description

The invention relates to the field of enrichment of magnetite ores and can be used to automate the process of denshamatization and magnetic separation of ores at a mineral processing plant.

The purpose of the invention is improving the accuracy of the control by the declaration of iron ore pulps.

The drawing shows a block diagram of a device for automatic control of the process of declaring.

.. The device consists of a sensor I of the density of the pulp to be discharged, a regulator 2, an actuator 3, pinch element 4, a sensor of the upstream speed sensor 5, a sensor 6 for the volume flow of the incoming flow 1 # a declarer of the volume flow sensor 7 for the unloaded pulp from the separator, block 8 for determining the speed of the upward flow in d, elam. the sensor 5 of the sensor 9 of the iron content in the drain of the drainage regulator of the corrective regulator 10,

The device works as follows.

The pulp enters through the supply pipe line s of the waste separator bowl. In the de-chmaator, the pulp is deposited and unloaded through the sand opening. WITH HELP: sensors 6 and 7 measure the volume flow rates of the incoming and unloading pulp. The signals from the sensors are converted in the upstream flow rate determining unit 8 into a signal proportional to the current input flow rate in the declarer. This signal, together with the signal of the time limit 5, is supplied to the regulator 2, which with the help of the actuator 3 and the pinch element 4 of the device establishes such a flow, the discharge of pulp from the declarer.

wherein the speed of the upstream becomes equal to a given one. In addition, when the type of ore processed is changed, the upstream flow rate at which optimal removal of slags, changes, as a result of which non-optimal vyios of thin ishams into the discharge of depgshamator occurs and, as a result, the content of iron in plum deulamator. The signal of the iron content sensor 9 in the middle of the declarator and with the help of the adjusting regulator 10 changes the setpoint rate of the upstream flow to the value at which the maximal removal of the thin pshams occurs,

As a result, such an upstream flow rate in the advertiser is established, which ensures that the iron content in the outlet of the advertiser falls in the required range, i.e., is optimal for this type of machine.

The range of density of the pulp required for magnetic separators, which is required for magnetic separators, is determined experimentally on the condition that the allowable loss of a magnetic material into the tails of magnetic separation is ensured,

Thus, when the density of pulses in the unloading of the declarer measured by the density sensor of the discharged pulp coming out of a given interval, the setpoint is also corrected for the speed of the upstream flow in the depshamater.

The use of the invention allows to maintain the process of decalcification in the optimal mode, to ensure the required quality of desliming of ore pulps and the reduction of losses of a magnet into the discharge of the straister and the tails of magnetic separation.
