Mineral grain oriented locator

Abstract

The invention relates to a mineral grain oriented locator, which combines pushing force of a conveying belt, magnetic conduction rings (4) and magnetic rings (3), wherein the magnetic conduction rings (4) and the magnetic rings (3) are assembled on a magnetic roller (2). A guide location plate (1) is arranged above the magnetic roller, sawtooth openings (11) with the quantity corresponding to the quantity of the magnetic conduction rings and recessed side by side are arranged at the lower edge of the guide location plate, and the center of each sawtooth opening corresponds to the center of each magnetic conduction ring. Each convex baffle is folded into an angle of 20 degrees to 60 degrees to form a convex baffle bevel (6) for guiding mineral grains, the optimal angle is 45 degrees, and the direction of the bevel is coincident with the rotation direction of the magnetic roller in running. An adjustment sleeve (12) of the guide location plate is sleeved in adjustment supporting round shafts (9) at the upper portions of supporting rods (10), and adjustment screws (7) matched with the adjustment sleeve for use are arranged on the adjustment sleeve and used for adjusting the center of each sawtooth opening to correspond to the center of each magnetic conduction ring. Supporting rod adjustment screw holes (8) are arranged at the lower portions of the supporting rods and used for conveniently adjusting the distance between the guide location plate and the conveying belt (5), and the optimal distance is that the guide location plate does not abrade the conveying belt when the magnetic roller rotates. In the using process of the mineral grain oriented locator, after a motor of a magnetic separator is started, a triangle belt drives the magnetic roller (2) to rotate, the conveying belt (5) sleeved on the magnetic roller rotates along with the magnetic roller, and ores sliding off to the conveying belt are pushed to the direction of the magnetic roller. When the ores are pushed to the guide location plate (1), some ores pass through the centers of the strongest magnetic conduction rings (4) along the sawtooth openings (11), some ores meeting with the convex baffle bevels (6) slide through the central line of the magnetic conduction rings (4) by means of the pushing force of the conveying belt and then pass through the centers of the strongest magnetic conduction rings (4) through the sawtooth openings.

Description

Technical field [0001] The invention relates to a part of a mine magnetic separation equipment, especially a mineral particle guide locator. Background technique [0002] There are many types of mineral separation equipment available, and there are two types of magnetic separation equipment available on the market, dry and wet. When manufacturing neodymium iron boron magnetic rollers by the traditional process, the S pole and N pole series magnetic ring of the magnetic ring are assembled on the rust-free steel shaft, so that the magnetic force is doubled. The magnetic force is all accumulated on the magnetic ring, and the magnetic ring is connected in series. There is no magnetic force on the curved surface, and the magnetic rollers of different lengths are assembled in sequence. Even after using the above process, the weakly magnetic large particles of manganese ore cannot be absorbed, which is limited by the magnetic energy product of the NdFeB magnetic ring and the limit bott...

Problems solved by technology

Therefore, the diameter and thickness of the magnetic ring can only be increased to increase the magnetic energy product of the magnetic ring. While the magnetic ring is thickened, the disadvantages are also increasing. For example, the thickened magnetic roller on the market has an outer diameter of 160 mm. The inner diameter is 70 mm, the thickness is 24 mm, and the thickness of the magnetic ring is 4 mm. After assembly, the surface magnetism is only 12,000 gauss, and the maximum can only magnetically separate 14 mm of manganese ore; such a magnetic roller has a small magnetic area on the surface, and the magnetic Minerals pass through the middle of the two magnetic rings in the radial direction, and all of them enter the waste bin, which affects the quality of magnetic separation, the recovery rate of finished ore is low, and the content of finished ore in impurities is high
