Although there are many laboratory-type electric sorters in various countries in the world, there are not many real-world effects. Now we only introduce the XDFф250×200mm and the American Capco type, which have been widely used at home and abroad, both of which are drums. formula.
(1) XDFф250×200mm laboratory type electric separator

The electric sorting machine is composed of various parts, and the power supply voltage is 0-60 kV (adjustable). The heating device is designed in the mine bucket and the drum, and can be self-controlled, and the electrode structure is different from the English. , the United States, Japan and West Germany, the Soviet Union, a high efficiency of sorting, but the power supply can only use negative electricity. The sorting particle size is from -1 mm to 20 μm and can also be used for the classification of fine-grained materials. Its shape and structure are shown in Figure 1. It is characterized by high voltage, maximum voltage of 60 kV, many adjustable parameters, and intuitive, especially the electrode structure is variable, and the efficiency of primary sorting is the highest at home and abroad.

(2) Capco experimental high-voltage electric separator This is an experimental research-type drum high-voltage electric separator produced by Carpco. Its appearance and structure are shown in Figure 2.

This machine is characterized by its electrode structure, that is, the corona pole and the static electrode are mixed together, and the power supply can also flexibly adopt negative or positive power. According to the need, several different specifications of the drum can be replaced, a total of 152, 254, 356 mm. For the diameter and low voltage, the non-conductor mineral is removed by a pressure plate brush; when the pressure is high, the non-conductor on the drum surface is replaced with a special AC discharge electrode. The whole machine is beautiful in appearance, the sorting process is intuitive, and there are many variable parameters.
The short-circuit voltage is still low, and the maximum voltage is only 40 kV. The adjustment of the electrode is inconvenient, and it must be adjusted after stopping. There is no heating device in the mine bucket and the drum. The infrared tube only depends on the drum. The experiment required. The end result is that the effect of a sorting is not satisfactory.
