Measurement of magnetic field strength of PTMS permanent magnet drum magnetic separator (Ⅰ)
Magnetic separation process
The measurement method of magnetic field strength of PTMS permanent magnet drum magnetic separator is as follows:
(1) Select three sections along the axial direction of the cylinder: one of them is selected in the middle, and the other two sections are respectively taken at a distance of 200mm from both ends.

(2) The magnetic field intensity of several key points on the surface of the cylinder should be measured on each section. Generally, there are 3 points at the edge and middle of each magnetic pole (magnetic system edge 2 points are unexpected), and 1 point in the middle of the polar gap. If the number of poles is N, the number of measuring points n =[3N-2 +(N-1)]= 4N-3. For example, the 3-pole magnetic system is 9 points, the 4-pole magnetic system is 13 points, and so on. PTMS magnetic separator can remove iron (FE2O3) inside.

(3)Measure 3 ~ 5 points above each key point on each section at a certain distance from the barrel surface. Such as 10mm, 20mm, 30mm, 40mm, 50mm points away from the barrel surface. PTMS magnetic separator can remove iron (FE2O3) inside.
