(1) selection of three sections along the cylinder axis: one option in the middle, the other two sections were taken at a distance of 200mm at each end.
(2) in each section to measure the magnetic field intensity slip separator surface a number of key points, usually the edge of each pole and a total of three points in the middle (the magnetic system edge 2:00 eventuality), the middle of a cusp point, if the number of poles is n, then the measurement points N = [3n-2+ (n-1)] = 4n-3. As 3-pole magnetic system to 9 points, 4-pole magnetic system to 13 points, more than analogy.
(3) the average of the cylindrical surface of the magnetic field strength on behalf of the cylindrical surface of the magnetic field strength measured at various points, the same way, from the cylinder surface magnetic field intensity magnetic pulley separator certain height of each point of the average representative of the magnetic field strength of the arc.
(4) a certain distance away from the key points of the top of the cylindrical surface on each section measuring 3 to 5 points. As from the drum surface 10mm, 20mm, 30mm, 40mm, 50mm each point.
Before measurement, the first cylinder (and magnetic system) support from, in order to measure the height as appropriate. At this point magnetic system vertically downwards, but we do not see the poles at the outer cylinder, measuring point given inaccurate sprinkle some iron in the cylindrical outer magnetic pole attracting iron edge
More magnetic separator magnetic pole shape can be displayed. If you do not iron, can also be used to find some nails, nails can stand in the place that is the cylindrical surface of the magnetic pole center (or center CUSP), to find the exact location later be marked with chalk or a brush, and then Point by point measurements.
