For the measurement of the magnetic field strength of the permanent magnet cylinder PTMS Electromagnetic Separator, three sections are selected along the cylinder axis: one of which is selected in the middle, and the other two sections are taken at 200mm from each end. In each section, to measure the magnetic field strength of several key points on the cylinder surface. Generally, there are 3 points at the edge and middle of each magnetic pole (2 points at the edge of the magnetic system),
There is one point in the middle of the pole gap of the permanent magnet cylinder type PTMS Electromagnetic Separator. If the pole number is n, the number of measurement points is N= [3n-2 + (n-1)] =4n-3. For example, the 3-pole magnetic system has 9 points, the 4-pole magnetic system has 13 points, and so on. Each section has a certain distance from the cylinder surface. For example, 10mm, 20mm, 30mm, 40mm, 50mm away from the cylinder surface.
The average of the magnetic field intensity of each point measured on the cylinder surface of the permanent magnet cylinder type PTMS Electromagnetic Separator represents the magnetic field intensity of the cylinder surface, and similarly, the average of the magnetic field intensity of each point at a certain height from the cylinder surface represents the magnetic field intensity of the arc surface. Before measuring, support the cylinder (and magnetic system) to a height for appropriate measurement.
