A method for improving the iron removal efficiency of PTMS magnetic separator

feldspar processing

A method to improve the efficiency of PTMS magnetic separator for removing iron is to implement "short-time strong excitation" on the electromagnet, that is, a sensor is installed on the front of the pole shoe of the electromagnet and below the conveyor belt. The purpose is to use the sensor to detect the magnetic material farthest away from the pole shoe and with the weakest attraction effect. The sensor then passes the detected signal to the strong-excited rectifier,


PTMS magnetic separator

When the magnetic material passes through the PTMS magnetic separator below the pole shoe, a high supply voltage is applied to the magnet ring for a short time, so as to produce a strong magnetic flow, so that the electromagnetic suction surges for a short time, so that the magnetic material buried in the deep can be absorbed out, and then the voltage is restored to the usual power supply state. The purpose of the sensor in front of the pole shoe is to avoid interference from the electromagnet field,


what is magnetic separation?

In general, when the iron is in the upper or middle part of the coal seam, the PTMS magnetic separator sensor does not allow it to send effective signals. Only when the iron is buried at the bottom of the coal seam, the PTMS magnetic separator sensor can send effective signals. The sensor has the following links: normal excitation trigger control link is mainly for normal excitation control of the electromagnet. It is necessary to have the function of triggering pulse phase shift to control the thyristor of the main circuit to achieve normal excitation current regulation.
