First, the concentration of separation
The size of the sorting concentration determines the slurry flow rate of a certain amount of minerals, which affects the sorting time of the ore particles. The concentration is high, the flow rate is slow, the resistance is large, and the gangue is easily mixed in the concentrate to reduce the quality of the concentrate. However, due to the long selection time, it is beneficial to the recovery rate. Conversely, if the separation concentration is low, the concentrate grade can be higher, and the tailing grade will also increase, resulting in a lower recovery rate.
Second, the magnetic separation angle
If the magnetic system declination is not appropriate, it will obviously affect the sorting index. The so-called magnetic system declination is the angle between the center line of the magnetic system arc surface and the vertical line of the cylinder center. After the magnetic system, the tailings grade is low, but after the large deviation, the grade of the tailings is increased because the concentrate cannot be lifted to the concentrate end. If the magnetic system is ahead of the head, the concentrate will be lifted too high, the sweeping area will be shortened, and the tailings grade will be raised, so the magnetic system declination should be adjusted to a moderate position.
Third, the work gap
The distance between the cylinder surface of the rough selection zone and the bottom plate of the tank is called the working gap. The size of the working gap will affect the effect of sorting. A large gap, a large flow of the slurry also help to improve the processing amount, but far away from the cylinder surface, a lower magnetic field strength, the tailings grade will raise, lower metal recovery.
Conversely, if the working gap is small, increasing the magnetic field force will lower the concentrate grade, but the recovery rate can be higher. If the working gap is too small, the slurry flow rate will be too fast, so that the ore particles can not be sucked to the surface of the cylinder and will be brought to the tailings by the slurry flow, which will cause the tailings grade to rise, and even the tailings will be difficult to discharge. "phenomenon. Therefore, care should be taken to ensure proper working clearance during the installation and maintenance of the magnetic separator.
Fourth, the cylinder speed
The rotation speed of the cylinder also has an influence on the selection index. The rotation speed is low and the output is low. The rotation speed is high, the centrifugal force of the ore particles is large, the magnetic turnover effect per unit time is increased, the concentrate grade and processing capacity are high, and the recovery rate is lowered. .
In addition, there are other small details that can affect the efficiency of the magnetic separation, such as the adjustment of the blown water of the ore and the flushing water of the concentrate. Regardless of whether you are in life or at work, you should always pay attention to it. Red Star Machine also hopes that everyone can continue to learn at work, keep improving, grow constantly, and constantly have more and better new discoveries.
