Analysis of dry and wet magnetic separation under different productivity of magnetic separator according to test
The above-mentioned ore-feeding magnetic separator is used for sorting the crushed ore which is generally pre-desilted, and the particle size characteristic curve is a straight line or a convex curve, and the result of dry and wet magnetic separation under different productivity of the magnetic separator.
The particles of the material (what is the mud of hematite and quartz) during dry selection become 2-0 mm, the particle structure of 74 μ or less accounts for 4%, and the peripheral speed of the roller is 39 cm/sec. In the wet selection, the particle size of the washed manganese ore is 3-0 mm, the particle fishing of 74 μ or less accounts for 2%, and the rotational speed of the rotating roller is 44, 63 and 86 cm/sec, respectively, and the relationship between the beneficiation efficiency and the unit productivity.
Comparing the beneficiation efficiency and unit productivity data of dry and wet magnetic separation, it is known that as the productivity increases, the beneficiation efficiency gradually decreases (not sharply). Therefore, it is difficult to select the normal productivity of sorting a certain ore under certain sorting conditions.
The criterion for determining the normal productivity of a magnetic separator is that the beneficiation efficiency is not less than 70%. In this case, the unit productivity of the above-mentioned ore dry-roller magnetic separator in the selection of 2-0 mm material is approximately equal to 25 kg/hr·cm, while the wet magnetic separator is 3-0 in the sorting size. The unit productivity of millimeter ore is about 15 kg/hr·cm.
During wet selection, the peripheral speed of the roller is increased from 44 to 63 cm/sec, which can increase the manganese content and beneficiation efficiency in the concentrate. However, if it continues to increase to 86 cm/sec, the recovery of manganese in the concentrate will decrease due to the increase of the centrifugal force acting on the ore particles, thereby degrading the beneficiation efficiency.

The trunking Rail system mainly contains some accessories that match the Grille Light, such as rails, trunking, Connection Accessories, and Suspension Accessories. Because there are many ways to install this Grille Light.
Guide Rail: This installation method relies on the Track head to conduct electricity, and the Led Grille Light can move freely on the rail.
Bridge: This installation method is to connect trunkings with Connection accessories, and the wires can enter the lamp body through trunking. The entire lamp body can be hoisted and ceiling mounted.
Trunking: Although this model and Bridge have trunking, the two styles of trunking are different. This type of trunking is already wired before leaving the factory. In other words, as long as the first one is connected to the mains, the other lights are connected to the lights.
If you want to understand these installation methods more clearly, you can watch the video.
If you don't know what accessories you need, as long as you tell us your needs, we can match them for you.
