PTMS MAGNETIC SEPARATOR
what is magnetic separation in science？
There are two kinds of PTMS electromagnetic separator: electromagnetic and permanent magnet. With the continuous development of permanent magnetic materials, especially the appearance of rare earth permanent magnetic materials such as Ndfeb, PTMS cylindrical magnetic separator has basically realized permanent magnetization. In recent years,PTMS has done a lot of research and experiments on the upsizing of permanent magnet drum-type magnetic separator, as well as on the feeding mode, magnetic meter and tank structure, etc., and some achievements have been made. PTMS'S BJ and BW series cylinder PTMS magnetic separators have a maximum size of 1 050mm× 3 000mm and a surface magnetic field intensity of 120 ~ 400kA/m. Their magnetic system and separation tank are specially designed. The backwash water device is provided at the feeding place, and the magnetic force can be adjusted to form the multi-field separation process of gravity, hydraulic, inertial and magnetic forces. The magnetic minerals move in reverse with the overflow, and a part of gangue along with the overflow discharge from the back of the overflow weir into the tailings, realizing the first separation of fine tail. The magnetic concentrate was impacted by the reverse flushing water, which destroyed the magnetic agglomeration and made gangue escape from the magnetic mineral, and discharged along with the overflow, realizing the second separation of the selected mineral. The fine grade monomer iron concentrate and the eutrophication body mixed in gangue continue to be influenced by magnetic force during the discharge process and settle to the bottom of the tank to be sent to the sweep section for recovery. The above process improves concentrate grade and beneficiation efficiency. At present,BJ, BW series cylindrical PTMS magnetic separators have been used in many concentrators, which have obviously improved their economic and technical indexes and equipment level. PTMS 15 type permanent magnet magnetic separator, the use of composite magnetic ferrite magnetic blocks and a small amount of ndfeb, high magnetic induction intensity, the depth of an applied magnetic field, ndfeb magnets used for tailings sweep district, make the cylinder surface magnetic induction intensity of 200 mt to the tailings from a ore concentrate discharge outfalls gradually strengthen, to the tailings and district reached 280 mt, but from the cylinder surface of 50 mm in average magnetic induction intensity is still more than 100 mt. The equipment can also adjust magnetic system position, working clearance and concentrate discharge clearance according to production needs. The above features increase the equipment processing capacity and improve the selection index. PTMS XC series 1 200mm × 3 200mm wet-cartridge PTMS magnetic separator with large handling capacity can handle up to 160t/h per unit. Under the condition of iron grade 29.34%, the ore dressing indexes of concentrate iron grade 47.38%, yield 56.97%, iron recovery 91.99% and tailing iron grade 5.46% can be obtained. PTMS YC series permanent magnet pulsating PTMS separator adopts a large Angle magnetic system to enhance magnetic rolling of magnetic minerals on the surface of the cylinder, and a magnetic field pulsating device is set up. The non-uniform magnetic system is adopted and a deep-slot-type semi-countercurrent tank is configured to add rinsing water at the discharge end of the concentrate, thus greatly improving the concentrate grade. PTMS BX series permanent magnet separator, due to the number of magnetic poles (8 or 10 poles), large magnetic system inclining Angle, long magnetic circuit, more magnetic particle rolling times, high magnetic field strength, high tailings overflow port, so it is conducive to improve the grade of concentrate and metal recovery. After the customer adopted BX series magnetic separator, the final concentrate grade increased from 66.08% to 67.50%, which can increase the benefit every year. In customer tests,BX series magnetic separator improved grade 2.07%. The T series of new high-efficiency magnetic separation equipment developed by PTMS in recent years. Based on the latest "twin" design concept, correct the defect of the traditional drum magnetic separator design and manufacturing, adopt the reasonable structure of magnetic system and manufacturing technology, cooperate with high-performance materials, in the manufacture of magnetic system design breaks through the traditional magnetic separator magnetic series magnetic circuit structure, the formation of the magnetic field gradient magnetic disturbance factors, smooth, high magnetic field, and designed to match the multi-function tub, within a reasonable process, can break through the traditional concept of magnetic separation, at the same time to obtain the high grade and high recovery rate. T series high efficiency permanent magnet drum-type PTMS magnetic separator has the characteristics of large magnetic cover Angle, long separation band, magnetic system divided according to function, uniform gradient magnetic field, strong magnetic field force, rinsing device with concentrate, etc. High efficiency permanent magnet drum-type PTMS separator has been used by many customers and has obtained significant economic value. PTMS GT series large and efficient permanent magnet drum-type magnetic separator, the magnetic induction intensity of the separator 350mT, design processing capacity of 800 ~ 1 000m 3/h. After using this equipment, the recovery of concentrate can be improved effectively. In the customer's industrial test, GT series permanent magnet drum-type PTMS magnetic separator is used, the tailing grade is 1.5% lower than the original index, the recovery is about 95%, and the average is 2.5% higher than the original index, which reduces the cost of mineral processing and improves the production efficiency. GT series high-efficiency permanent magnet drum-type magnetic separator is the largest of PTMS products and the largest single processing capacity of the drum-type magnetic separator, which is in line with the trend of large mineral processing equipment.
