Embodiment Construction

[0010] The example structure of the water-spraying wet permanent magnet magnetic separator is shown in the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings.

[0011] refer to figure 1 , The structure and material of the magnetic separation cylinder 1 and the permanent magnet system 2 used in this magnetic separator are the same as those of the current wet permanent magnetic cylinder magnetic separator. Depending on the size of the cylinder, the magnetic envelope angle is required to be about 123°-130°, and the magnetic declination angle is 0°-10°. One of the differences of this magnetic separator is the structure of the sorting box. The sorting surface of the sorting box is high at the front and low at the back. The lower arc-shaped sorting surface, the selection surface, the rough selection surface, and the sweep-selection surface are arc surfaces respectively. The center angle of the arc surface of ...

Abstract

A magnetic separator suitable for the granular materials with granularity less than 6 mm has a separating case with special function. Said separating case has longer separating band, water spray function on the bottom of separating plane and sorting function for coarse and fine tailings. The coarse, fine and final separation steps can be performed in one pass. Its advantages are high separating quality, recovery rate, low wear, and long servive life.

Description

technical field [0001] The invention relates to a magnetic separation and separation device applicable to materials of various particle sizes of -6mm. Background technique [0002] The existing wet permanent magnetic drum magnetic separator is divided into three types according to the structure of the sorting box: downstream type (CTS), countercurrent type (CTN), and semi-countercurrent type (CTB). The characteristic of the downstream magnetic separator is that the flow direction of the pulp in the separation area is consistent with the movement direction of the magnetic separator cylinder, the separation belt is short, the tailings discharge point is low, the selection belt is long, and the medium ore discharged from the selection cannot Return to re-selection and directly enter the tailings, so the product grade is high, but the recovery rate is low, it can only be applied to the selection, it can separate thicker (-6mm) materials. The characteristic of the counter-curren...
