Structure and factors affecting sorting
This electric selection machine mainly consists of a heating and feeding device, corona electrode, deflection electrode, ore slide plate, and drum
It consists of several parts such as electrodes, brushes, ore sorting adjustment plates, and product funnels.
Factors affecting sorting efficiency of high tension separators
The factors that affect the sorting effect mainly include mineral particles, dryness, heating temperature, drum speed,Electrode voltage and electrode position, etc.
1. mineral particles
The minimum particle size of minerals is generally 0.074mm, and the sorting effect is poor if the particle size is too small. The maximum particle size is 3mm.
2.Drying degree
The drying process and heating temperature of minerals have a significant impact on the sorting effect. When minerals are relatively wet, they can lead to The surface conductivity of electric minerals and non-conductive minerals is not significantly different,
3.Heating temperature
If the heating temperature is very high,the sorting effect is not good
At the same time, it can also lead to poor sorting efficiency. The optimal heating temperature should be determined by experiments, while striving for mineral dryness
Clean, without any mineral mud contamination.
4.Drum speed
The drum speed is related to the mineral particle size. When the particle size is large, the speed should be small, and when the particle size is small, the speed should be large. When most of the minerals in the ore are non-conductive, in order to improve the product quality of non-conductive minerals in the sorting process, a slightly larger speed can be selected.
If most of the minerals are conductive minerals, in order to improve the quality of conductive products in sorting, the selected rotation speed can be slightly lower.
5.Electrode voltage and electrode position
The electrode voltage is also related to the mineral particle size. When the particle size is large, the voltage should be higher, and when the particle size is small, the voltage should be lower. To improve the quality of conductive products, the voltage can be slightly higher, and to improve the quality of non-conductive products, the voltage can be slightly lower.
Use Attention of HT separators:
1. This product is for extracting dry ore and wet ore should not be extracted.
2. Waterproof and moisture-proof measures must be taken on the body to prevent electric leakage accidents when touched.
3.During the equipment debugging phase, the power must be disconnected before proceeding with the operation.
4.During the production process, the production effect of the equipment can be observed through an observation mirror, and it is strictly prohibited to reach out and touch the DC high-voltage lines inside the machine.
5.Those who are not familiar with this equipment shall not operate it arbitrarily, and there shall be no less than two operators

Maintenance and safety technology of electric selection machine
1. The electric selection machine should be equipped with a grounding device nearby, with a grounding resistance of less than 10 ohms and a natural grounding nearby
The ground can be utilized, but if its resistance does not meet the above requirements, an artificial grounding body should be added,
The grounding device can also be shared with the grounding devices of other lines, but the grounding device is located near the equipment
It is appropriate.
2. The host rack, high-voltage electrostatic generator, and control box are each equipped with grounding bolts, and separate branch lines should be used,
Connect to the grounding main line separately and do not connect in series.
3. There should be a strong electrical connection and connecting wires between the host rack, high-voltage electrostatic generator, and control box
It should be firmly fixed on the grounding bolts of both.
4. The bearings of the upper and lower rollers should be inspected and oiled regularly (about three months).
5. When the high voltage is disconnected, there is still residual charge on the high voltage electrode, which must be discharged with a grounding discharge device,
Only then can they come into contact with it. The grounding arrester can be made of copper wire with a diameter of about 2 millimeters and a length of 250 millimeters,
seventy-eight
One end is made into a circular hook, which can be placed on the high-voltage electrode, and the other end is connected to any bolt of the frame with a flexible wire
Above, the grounding arrester is made of insulated material or wooden material wrapped around copper wire to create a handle.
6. Regularly check whether the setting values of the current relay and time relay in the high-voltage electrostatic generator are positive
Indeed, the former has a set current of approximately 2 amps, while the latter has a set time of 0.51 seconds, which should not exceed 1 second.
7. Before operation, pay attention to whether the reading of the drum motor is stable at the required value, and pay attention to the reading of the high-voltage ammeter
Is it normal.
8. The transformer oil inside the high-voltage electrostatic generator must be sampled regularly (every six months) for withstand voltage testing
If the pressure level is less than 25 kV, filtration or replacement must be carried out between the transformer oil level and the oil tank cover
If the distance is greater than 25 millimeters, refuel.
9. The output terminal of the high-voltage electrostatic generator is connected to the high-frequency cable of the high-voltage electrode, and its rated operating voltage is only
Thousands of volts, and the maximum high voltage of the electric selection machine can reach 22 kilovolts. Therefore, it is necessary to shorten the transmission of high-frequency cables as much as possible
Electrical length refers to shortening the distance between the high-voltage electrostatic generator and the host. The environment in which cables are laid along the ground
Efforts should be made to keep it dry, and wooden boards can be used to cushion it. During operation, operators should try to avoid contact with cables.
10. About 5mm thick rubber can be laid on the floor in front of and behind the high-voltage electrostatic generator and the main unit
Leather boards make operators safer.
12.Those who are not familiar with this device are not allowed to operate it at will, and there must be at least two operators
