Types of high-voltage electric selection machines:

Electric beneficiation machine is a type of beneficiation equipment that separates particles with different electrical properties, with various types available. Mainly classified according to the following characteristics:

1According to the characteristics of the electric field, there are three types:(1)Electrostatic beneficiation machine,(2)Electric corona separator,(3)Composite electric field selection machine.

2There are three methods for charging mineral particles:(1)Contact with an electrified sorting machine,(2)Friction electric selection machine,(3)Electric selection machine with corona discharge.

3According to structural characteristics, there are three types of electric separators: drum type (or roller type or drum type), box type, tube type, and plate type.

high pressureStructure of plate type electric separator:

The grounding electrode of the plate type electric selection machine is a carriage, with a high-voltage static electrode on top, which is supplied with high-voltage negative or positive electricity. The cross-section of this electrode is elliptical and supported on the carriage. The ore is fed through the feeding plate (vibration) and slid down to the grounding electrode sliding plate, entering the electric field action area. The ore particles are induced by the electrode and charged, while the conductor ore particles are induced to carry a charge sign opposite to that of the charged electrode, thus attracting towards the electrode. However, due to the combined effects of vibration and gravity, their motion trajectory is different from that of non conductors, and they are discharged from the front; Although non-conductive mineral particles are subjected to the electric field of the electrode, they can only polarize. Due to the force of vibration and downward flow of mineral flow, they continue to flow downward without attracting towards the electrode. In sorting, fine particles are most affected and are therefore always contained in the conductive product.

This type of electric sorting machine is mainly used to separate conductive minerals with low content from a large number of non-conductive products. At present, a relatively large number of coastal sand mines in Australia are used to separate small amounts of hematite and ilmenite from zircon coarse concentrate, and often many of these electric separators are connected in series to form one or several series of continuous sorting. Some factories originally used the United StatesCarpeoHigh voltage electric selection machine, due to the unsatisfactory sorting effect, has greatly improved the beneficiation effect after using this type of electric selection machine for selection.

high pressureInstructions for using the electric selection machine:

Electric selection, as an important mineral processing technology, has been widely used in various fields, especially for the selection of certain mineralsseparate, showing its unique characteristics, can be solved

Electric beneficiation is mainly applied in the following fields to solve problems that are difficult to solve by other beneficiation methods:
　　1Selection of heavy minerals such as sandy gold from coastal sand minesselected.
　　2Colored and RaremetalSelection of minerals, such as separation of scheelite and cassiterite, separation of scheelite and scheelite, primarySeparation of ilmenite and gangue.
　　3The selection of black metal minerals, such as the production of ultra pure iron concentrate, chromite, and manganese ore.
　　4Sorting of non-metallic minerals such as graphite, quartz, feldspar, asbestos, and apatite.
　　5Separation of non-ferrous metals and non metals such as copper, tin, aluminum, and plastics from waste materials.
Electric selection is the process of separating materials by utilizing the differences in their electrical conductivity, under the influence of mechanical and electric forces in a high-voltage electrostatic field (or a composite electric field with high-voltage corona).
The elliptical electrode inside the electric selection box is connected to the negative output of the transformer through a digital microampere meter, and the conductive plate is connected to the lower end of the high-voltage capacitor/Transformer grounding/Transformer high voltage tail/The grounding of the control box should be connected together with the grounding, and the grounding wire should be firmly connected. The depth of the grounding wire inserted into the ground should be at least half a meter. The upper end of the high-voltage capacitor is connected to the negative pole of the transformer output and the lower end of the microampere meter. The two outputs of the control box are connected to the input of the transformer, and the two instrument lines of the control box are connected to the instrument lines of the transformer.
