Problems solved by technology
[0003] The existing magnetic separator coils are arranged horizontally, which can only form a vertically downward magnetic field. This method does not make full use of the ore dressing space. Mineral particles move vertically downward under the action of magnetism and gravity, and the trajectory is Straight line, the time to pass through the concentrator is short, and it is easy to cause the loss of concentrate

Embodiment 1
[0034] [Example 1] Taking a cylindrical magnetic separator as an example, the projection of the winding on the horizontal plane xoy is circular, and the interior of the circular ring is composed of several enameled wire conductors (7). The cross section is rectangular, see Figure 7 , is a schematic diagram of the winding method of the enameled wire inside the excitation coil in Embodiment 1. The enameled wire conductors (7) have a total of 4 rows and 8 columns. The labels of the enameled wire conductors (7) in the first column are (1aa, 1ba, 1ca, 1da) from high to low, and the labels of the enameled wire conductors (7) in the first row are from outside to inside The order is (1aa, 11ab, ... 1ah), and the coil is wound in the order of (1ah, 1ag, ..., 1aa, 1ba, 1bb, ..., 1bh, ... 1hh). The number of columns of enameled wire conductors (7) And the number of rows is determined according to the actual required magnetic field strength.

The invention relates to a magnetic separation column winding. The magnetic separation column winding comprises a plurality of groups of excitation coils, each group of the excitation coils are divided into two layers, the excitation coils of the upper layer and the lower layer are of the same bending structure and are oppositely arranged forwardly and reservedly in a normal direction respectively, and the bending points of the excitation coils are staggered with an angle; at least two bending points of the excitation coils are arranged and are uniformly distributed in the coil. Compared with the prior art, the magnetic separation column winding has the beneficial effects that a control system is adopted to supply power and achieve excitation, mineral particles are subjected to tangential action force as well as are subjected to gravity, vertically-downward magnetic field force, reverse water stream impulsive force, the current intensity of the winding on each layer is controlled to establish a magnetic field inclining to the plane and achieve magnetic control rotational flow, the original vertically-downward motion of the mineral particles is changed to be rotary downward motion, the movement distance of ore pulp particles in a magnetic separation column is increased, so that the recycling rate of effective minerals is improved and the recycling grade of concentrates is improved.
Description
technical field [0001] The invention relates to a mineral separator winding with one or more excitation coils, in particular to a magnetic separation column winding. Background technique [0002] The magnetic separation column is a kind of electromagnetic mineral processing equipment, which is used for the selection of ferromagnetic minerals. There are multiple groups of electromagnets on the inner cylinder of the magnetic separation column, which are automatically powered and excited by the DC electric control cabinet, and are formed in the separation body cavity of the magnetic separation column. The pulsating excitation field moves downward in sequence, and the treated slurry is injected into the ore from the upper part. Under the action of its own gravity and magnetic field, the ferromagnetic minerals in the slurry move downward and flow out from the lower part, and the tailings follow the water flow. On the top, it flows out from the overflow tank to achieve the purpose...
