Operation Rules And Process Of Magnetic Control Of Separation Equipment

By:


Magnetic control of process equipment in order to achieve the safe operation ofmagnetic separation equipment to ensure the smooth flow. It includes a continuous magnetic separation process equipment startup, shutdown, and troubleshooting automatic interlock operation; intermittent ore magnetic separator to process control and so on.

Continuous magnetic separation process in order to avoid flow blockage or overflow ore, usually equipment by reverse flow direction Mine started mining flow along the direction of downtime, failure alarm signal and stop sending equipment to the mining and automatic diversion to avoid accidents to expand. Control objective is to concentrate on ensuring the quality and recovery under the premise of improving the processing capacity of magnetic separation equipment. Magnetic Separator process parameters to the ore, pulp density, magnetic field strength, magnetic separator divided the constituency level, magnetic separator speed and grade of such concentrate and tailings.

Magnetic separation process control equipment, mainly magnetic separation process sequence control, to the ore deposits, the concentration of control plasma, magnetic separator and magnetic sub-constituency level control grade multi-parameter control. To mine on the continuous magnetic separator, such as the interruption to the mining of high gradient magnetic field of electromagnetic separator, in accordance with certain procedures required to run: (l), magnetic separator connected Power supply For excitation; (2), into the pulp to a magnetic separator and sorting; (3), stop and make the slurry returns to the ore mixing tank; (4); disconnect power to the magnetic excitation; (5), discharge magnetic magnetic minerals within the selected machine. And the cycle repeats the procedure. Magnetic separation process sequence control by the sequence controller (see mineral processing equipment in order controller) to achieve, according to the technical requirements of the order of pre-programmed control and into order controller.

Magnetic grade multi-parameter control process in the magnetic separation, magnetic separation quality factors affecting the nature of ore to ore, pulp density, sub-constituency level, magnetic separator speed, wash water flow, flow and discharging material magnetic field strength. Such as continuous high gradient magnetic separator, electromagnetic separator process to mine the nature and amount of ore is a major disturbance, then the impact of concentrates, tailings grade of the main control parameters of a hand selected pulp density, sorting disk rotation speed and magnetic field strength , the relationship between them with mathematical models to represent and use of multi-parameter control systems. Control system based on the original, refined, a useful component of the tailings grade, pulp density, to measure parameters such as ore, pre-established mathematical model of computing, issue the appropriate command, respectively, the corresponding execution control device to regulate the flushing water separator , sorting disk rotational speed, magnetic field excitation current and dehydration (grade) equipment product concentration, to enable the tailings grade meet process requirements.
