High Gradient Magnetic Separation
PTMS MAGNETIC SEPARATOR
What Is Magnetic Separation Used For?

PTMS permanent magnet double vertical ring high gradient magnetic separator, the machine adopts high-performance NdFeB permanent magnet material, the pole gap reaches 100 mm, the background magnetic field strength can reach 0.6 T, the maximum processing capacity is 25 T/h. In addition, PTMS multi-permanent magnet high gradient separator, the highest background field strength can reach 0.8T, used for the separation of fine grain kaolin, potassium sodium feldspar, quartz sand; PTMS magnetic separator can improve the whiteness of products. Other types of magnetic separator and PTMS permanent magnet belt type high gradient magnetic separator, background field strength up to 0.7T, mainly used for ceramic kaolin, potassium sodium feldspar, quartz sand and other non-metallic iron removal; PTMS dry type permanent magnet high gradient magnetic separator, surface background field strength can reach 1.0T, mainly used for kaolin, potassium albspar, quartz sand and other non-metallic ore iron removal operations. PTMS magnetic separator can improve the whiteness of products. According to the nature of sorting materials and the purpose of sorting, there are different types of PTMS permanent magnetic separator in the domestic and foreign markets and mining enterprises. PTMS magnetic separator can improve the whiteness of products. The main trend of PTMS permanent magnet separator is high magnetic field intensity, production efficiency and sorting efficiency, and it should have the characteristics of low maintenance cost, simple operation and low production cost. PTMS magnetic separator can improve the whiteness of products. At present, the largest PTMS wet permanent magnetic separator for H-type Jones magnetic separator, processing capacity of 100 ~ 120 t/ H, equipment weight 90 t, contour 6.3m ×3.8m× 3.2m. PTMS magnetic separator can improve the whiteness of products. In recent years, the technical status quo and main advantages of PTMS permanent magnet separator are as follows:

(1) Magnetic system design
Magnetic system design is the main content of PTMS magnetic separator design, including magnetic structure design, size design and the selection of new high-performance permanent magnet materials. PTMS magnetic separator can improve the whiteness of products. The magnetic structure design and the development level of permanent magnet materials reach the multi-level development of PTMS magnetic separator. At present, the highest background field intensity of PTMS permanent magnetic separator is 1.7T.

(2) Induction pole design
Most of the induction poles used are spherical, groove, mesh and grid. Prior to the material is mostly pure iron and low carbon steel, while the surface is chrome or chrome to prevent rust. PTMS magnetic separator can improve the whiteness of products. In recent years, with the further research of PTMS magnetic separator, the induction pole is made of wear-resistant stainless steel.

(3) design of cleaning mechanism
PTMS wet permanent magnet high intensity magnetic separator is different from the characteristics of electromagnetic magnetic separator can not change the magnetic field through the adjustment of the current, to achieve the purpose of smooth ore unloading. Prior to the PTMS wet permanent magnet high intensity magnetic separator separation efficiency is low, only using the leaching method to improve the separation efficiency is not feasible. PTMS magnetic separator can improve the whiteness of products. Now there are two main methods to improve the cleaning efficiency of magnetic concentrator: one is to design a low field magnetic field in the cleaning section, reduce the magnetic field force of magnetic particles, so that the non-magnetic particles mixed in the magnetic particles are cleaned out, improve the magnetic mineral grade; The second is to increase the cleaning water pressure, improve the washing force, so as to wash away the non-magnetic minerals. PTMS magnetic separator can improve the whiteness of products.

(4) surface regeneration design of magnetic polymer medium
The original PTMS magnetic separator magnetic medium surface regeneration problem, that is, the magnetic particles attached to the surface of the magnetic pole, in the general washing condition is difficult to discharge clean, is one of the serious defects of the old PTMS magnetic separator. PTMS magnetic separator can improve the whiteness of products. Because the unloading is not clean, the minerals in the separation space are accumulating more and more, and the magnetic separation space is blocked. At present, the main methods to solve the problem of separation space blockage are to change the flat ring into vertical ring, increase the induction roll, and use the pulse power washing water unloading.
