Increased demand for wet magnetic separator

Magnetic separators can be divided into different types of magnetic separators based on different working methods. The most common equipment in beneficiation work is wet magnetic separators and dry magnetic separators. Perhaps the operator may just start to use it. Time-division review of the magnetic separator consider the position of these two devices in the magnetic separator. At the beginning, I said that there are many types of magnetic separators. The same feature is the use of its own magnetic characteristics in the beneficiation technology, but the difference depends on the working methods of each magnetic separator. Having said that, for the more common dry magnetic separators and wet magnetic separators, they are attributed to complementary types of mechanical equipment. The disadvantages of dry magnetic separators themselves are completely advantageous in wet magnetic separators. reflect.


The wet magnetic separator has three tanks: downstream tank, countercurrent tank, and semi-countercurrent tank. Different tanks work differently for the fineness of the material. This detailed selection should be based on the surrounding environment, geology and material characteristics, and then combined with natural conditions to choose according to the characteristics of the equipment to prevent "unsuitability" "Operational questions arise.


The characteristics of the three tanks of the wet magnetic separator:


Compared with the counter-current and semi-flow tanks, the downstream wet magnetic separator has greater processing capabilities. The downstream tank is suitable for the rough selection and selection of relatively coarse-grained ferromagnetic materials. One feature of the downstream magnetic separator that needs attention is that the particle size of the ore must be strictly controlled. It cannot be too large or too small. The too large gangue cannot be separated from the magnetic object, and the magnetic ore is simply lost. For tailings, it will reduce the quality of the concentrate. Down-flow tank wet magnetic separator can complete the work of conjoined machine and improve the quality of concentrate. The countercurrent magnetic separator is suitable for the rough separation and sweeping of fine-grained strong magnetic mineral deposits. The recovery rate is high, but the concentrate grade is low. Because coarse-grained materials are easy to deposit and block the separation space, and they are not allowed to leave, the counter-current magnetic separator is not suitable for processing coarse-grained materials. Try to prevent the use of counter-current wet magnetic separators for selection. The semi-countercurrent magnetic separator has the advantages of its own downstream tank and countercurrent tank. The semi-countercurrent magnetic separator occupies a larger proportion in the technical process of mine design. It fully embodies the advantages of the downstream and counter-current types, and surpasses those two tanks. Because it is also suitable for the rough selection and selection of ore particles below 0.5mm, not only can multiple units be connected in series and parallel, but also You can also complete repeated scanning and selection.
