PTMS Magnetic Separation
What Is Magnetic Bead Separation?

PTMS magnetic separator magnetic separation process is mainly based on the magnetic difference of each mineral in the ore, under the action of magnetic force and other mechanical force to achieve mineral sorting, has been widely used in kaolin, potassium albinite, quartz sand, ferrous metal ore sorting, non-ferrous and rare metal ore selection, and some non-metallic ore sorting. PTMS magnetic separator can remove the iron inside (Fe2O3). In simple terms, the working principle of PTMS magnetic separator is that when the pulp into the sub-selection, magnetic particles are magnetized under the action of non-uniform magnetic field, attracted by the magnetic field on the magnetic separator cylinder, and then is transferred to the cylinder to the end of the discharge into magnetic products; PTMS magnetic separator can remove the iron inside (Fe2O3). And non-magnetic ore particles by the magnetic field force is small, still remain in the pulp, discharge into the non-magnetic products. PTMS magnetic separator can remove the iron inside (Fe2O3). In order to achieve the ideal magnetic separation effect, we must first understand what factors will affect the magnetic separation effect, so that we can pay more attention to the operation process, so as to get a good selection index. PTMS magnetic separator can remove the iron inside (Fe2O3). Influence factor 1: feeding particle size, feeding particle size is an important factor affecting the separation effect of magnetic separator. For most ores, the size of the feed size means the separation degree of ore monomer, that is, the separation degree between magnetic ore grains and gangue minerals. PTMS magnetic separator can remove the iron inside (Fe2O3). If the ore particle size into the magnetic separator is small, it indicates that the separation degree of ore monomer is high, and it is easy to obtain satisfactory separation index; If the particle size of the ore into the magnetic separator is coarser, it shows that the ore has not been fully disintegrated, and the magnetic ore particles are still combined with some gangue minerals, which directly affects the dressing indexes and reduces the grade of the concentrate. PTMS magnetic separator can improve the whiteness of products. Therefore, the particle size of the ore into the magnetic separator must fully realize the separation of monomers. Influence factor two: pulp concentration, here the pulp concentration mainly refers to the classifier overflow concentration. At this time, the concentrate particles are easy to be covered and wrapped by the fine gangue particles, resulting in the difficulty of separation between the two, which seriously affects the concentrate grade. PTMS magnetic separator can improve the whiteness of products. If the pulp concentration is too small, it means that the concentration of separation is too low, which leads to the increase of the flow rate, shortening the separation time, and making some small magnetic particles that could have been recovered enter the tailings and discarded. Usually, the slurry concentration can not exceed 35%, about 30% control. Of course, each plant or according to their own magnetic separation requirements and the actual situation to determine. Influence factors three: the size of the magnetic separator speed of the size of the magnetic separator mainly on the processing capacity of the magnetic separator has a greater impact, and then has a certain impact on the quality of concentrate. High speed, the processing capacity of magnetic separator is large, at the same time the small magnetic body and gangue minerals are not easy to separate out, only the magnetic higher ore particles can be separated, so the concentrate quality is relatively high. Low speed, magnetic separator processing capacity is low, by magnetic induction, weak magnetic particles can also be sorted out, affecting the quality of concentrate. In general, small diameter magnetic separator with high speed, large diameter magnetic separator with low speed. Take permanent magnet magnetic separator as an example, when the diameter is 1000mm, the magnetic separator cylinder speed is 23r/ min; When the diameter is 1200mm, the magnetic separator cylinder speed is 20r/ min. Influence factor four: the size of the magnetic system declination Angle. Usually, the magnetic declination indicating device is located near the shaft head of the transmission side, and the size of the magnetic system declination Angle can be adjusted by adjusting the nut. The effect of magnetic declination is mainly reflected in the concentrate quality and recovery. Take permanent magnet magnetic separator as an example, the magnetic system is small, small magnetic particles have the opportunity to be selected, help to improve the recovery rate, while the tailings grade is reduced; With large magnetic system deviation Angle, only the ore particles with larger magnetic properties can be sorted out, which can improve the concentrate quality to a certain extent. PTMS magnetic separator can improve the whiteness of products. But the size of the magnetic system deflection Angle is not free to adjust, must be adjusted according to the requirements of magnetic separation operation. In general, the magnetic declination Angle of the concentrator site is maintained at about 15° ~ 20° on average. The deflection Angle of the magnetic system can not be easily changed if there is no significant change in the production requirements. Of course, in the production practice, the influence of magnetic separator separation effect factors far more than the above four points. Mineral processing experts suggest that the mine owners in the purchase of magnetic separator equipment before, should be professional magnetic separation mechanism manufacturers to consult, combined with their own ore properties, plant conditions and investment costs and other actual conditions, get the ideal magnetic separation parameters, in order to correctly guide the magnetic separator operation, get the ideal separation effect.
