Magnetic separator block after installation is complete mineral sorting test

For most ores, the degree of separation marks ore monomer that is the size of the magnetic particles and gangue mineral particle separation of coarse or fine ore particle size.
If the ore to a small particle size, indicating a high degree of mineral monomer separation, can be satisfied with the sorting index; if given the relatively coarse ore particle size, mineral did not fully explain dissociation, monomer separation is not high, opposite the living body more That magnetism

Particles and gangue is still considerable parts together. Because of the living body also has a considerable magnetic sorting can choose up to a considerable part of that lower grade ore. Therefore, the requirements for the mineral magnetic separator for silica sand must be sufficiently achieved monomer separation.

For coarse-grained disseminated ore and gangue minerals as long as reached monomer separation on the line, not necessarily the size too small. Such ore sometimes coarse granularity although some, but not low quality sorting, the main reason is due to ore dissemination size
Coarse grinding to a certain extent useful minerals and gangue separated.

Counterflow separators

High Frequency Vibrating Sieve suitable for fine-grained magnetic minerals in the rough election and sweep the election operation, high recovery and concentrate grade is lower.Because coarse sediment clogging separation space, so the counter-current type magnetic separator is not suitable for coarse material.Upstream and a half can get high quality iron concentrate of magnetic ferrous traps machine, but also to get a better rate, a half upstream separators are widely used in practice.It is suitable for handling 0.5mm roughing and a selection of the following mineral grains, can also be multiple serial and parallel, multiple-scan election and selection.

-Flow separators processing capacity

-Flow New magnetic roll separator processing capacity, suitable for coarse-grained magnetic materials rough election and selection, also more than one series.-Flow separators when feeding a large quantity, coolant magnetic separators particles easily lost in tailings, and therefore to strengthen the operation management, controlled lower pulp level.

Methods of measurement of magnetic field strength wet permanent magnetic drum magnetic separator as follows:

(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.
