Problems solved by technology

[0003] When the existing magnetic separator is used to process iron ore, the separation effect of the concentrate is not good, the production efficiency is low, the cost is high, and the actual economic benefits cannot be obtained. Therefore, in order to effectively treat the iron ore ore sorting, the existing magnetic separator must be improved
[0004] Mineral material will precipitate in the magnetic separator, resulting in the mineral material content of the upper layer of pulp being lower than that of the lower layer of pulp; if the magnetic properties of the magnetic system are consistent, the degree of beneficiation of the lower layer of mineral material will not be achieved, affecting the concentrate sorting effect
[0005] If the sediment produced by the mineral material in the magnetic separator is not cleaned for a long time, it will cause the blockage of the lower feeding port, and it will also affect the separation effect of the concentrate

Abstract

The invention discloses an automatic control system and method of a magnetic separator for mines. The automatic control system comprises a material inducting module, a concentration detecting module, a PLC, a motor driving module, a display module, a sewage discharging module, a valve opening-closing module and a vibration frequency conversion module. The material inducting module is used for inducting whether materials pass through the material inducting module or not. The concentration detecting module is used for detecting the concentration of minerals at a mineral outlet. The PLC controls the motor driving module, the display module, the sewage discharging module, the valve opening-closing module and the vibration frequency conversion module through internal calculation to execute related operation. The automatic control system is simple in structure, rapid and convenient to use, small in occupied area and capable of being suitable for popularization; the rotating speed of a motor and the vibrating frequency of a vibrating device can be further automatically adjusted, accurate control over the system can be achieved, and concentrating efficiency can be improved; the safety and the stability of the magnetic separator are also improved; meanwhile, energy waste can be reduced.

Description

technical field [0001] The invention relates to the field of control systems, in particular to an automatic control system and method for a magnetic separator used in mines. Background technique [0002] Magnetic separator is used to remove iron powder in reusing powdery granules. Magnetic separator is widely used in resource recovery, wood industry, mining industry, kiln industry, chemical, food and other factories. It is suitable for magnetic particles with particle size below 3mm. Wet magnetic separation of iron ore, pyrrhotite, roasted ore, ilmenite and other materials is also used for iron removal operations of coal, non-metallic ores, building materials and other materials. It is the most widely used and highly versatile in the industry. One of the models. [0003] When the existing magnetic separator is used to process iron ore, the separation effect of the concentrate is not good, the production efficiency is low, the cost is high, and the actual economic benefits c...
