PTMS magnetic separation

what is magnetic separation?

PTMS cylinder magnetic separator, the maximum size of O1050mm×3000mm, simplified surface magnetic field strength 120-400Ka/m, the magnetic system and sorting tank design is unique, the mine is equipped with a reverse rinse water device, plus the magnetic force adjustable, formed the gravity, hydraulic, inertia force and magnetic force of the multi-force field sorting process. PTMS magnetic separator can improve the whiteness of products. The magnetic minerals move in the opposite direction with the overflow, and part of gangue enters the tailings from the rear overflow weir out of the tank with the overflow, realizing the initial separation of fine tailings. The magnetic concentrate was impacted by the reverse washing water, which destroyed the magnetic agglomeration, and the gangue escaped from the magnetic minerals and was discharged with the overflow, thus realizing the second separation of selected minerals. PTMS magnetic separator can improve the whiteness of products. In the process of discharge, the fine grade monomer iron concentrate and rich intergrowth mixed with gangue continue to be affected by magnetic force and settle to the bottom of the tank to be sent to the scavenging section for recovery. The above process improves the concentrate grade and beneficiation efficiency. PTMS cylinder magnetic separator has been applied in large concentrators, and the economic and technical indexes and equipment level of these plants have been improved obviously.
PTMS permanent magnet magnetic separator, using ferrite magnetic block and a small amount of NdFeB composite magnetic system, high magnetic induction intensity, magnetic field effect depth is large, NdFeB magnet is used for tailings scanning selection, the simplified surface magnetic induction intensity from concentrate unloading end of 200MT to tailings discharge port gradually enhanced, to the tailings scanning selection reached 280MT, However, the average magnetic induction intensity at a distance of 50mm from the surface of the simplified body is still above 100mT. The equipment can also adjust the magnetic system position, working clearance and concentrate clearance according to the production needs. The above characteristics increase the processing capacity of the equipment and improve the sorting index. PTMS magnetic separator can improve the whiteness of products. 1200mm×3200mm wet cylinder magnetic separator, its single processing capacity can reach more than 160t/h. Under the condition of feeding grade of 29.34%, the beneficiation index of concentrate grade of 47.38%, yield of 56.97%, iron recovery of 91.99% and iron grade of tailings of 5.46% can be obtained. PTMS permanent magnet pulsation magnetic separator, using large Angle magnetic system to enhance the magnetic rolling of magnetic minerals on the surface of the cylinder, and set up a magnetic pulsation device, using non-uniform magnetic system, equipped with deep groove type semi-countercurrent tank body, in the concentrate discharge end plus rinsing water, thus greatly improving the concentrate grade.
PTMS permanent magnet magnetic separator, due to the number of magnetic poles (8 or 10 poles), the magnetic system Angle is large, the magnetic circuit is long, the number of magnetic particles rolling, the magnetic field strength is high, the tailings overflow mouth is high, so it is conducive to improve the concentrate grade and metal recovery. The final concentrate grade was increased from 66.08% to 67.5% by using PTMS magnetic separator, and the annual benefit was 20 million yuan. The experiment in the concentrator showed that the PTMS magnetic separator improved the grade by 2.07%. PTMS magnetic separator can improve the whiteness of products.
