Abstract
The invention relates to a twin-roll magnetic separator. The twin-roll magnetic separator comprises motors 1, a speed reducer 2, a driving belt pulley 3, a driven belt pulley 5, a feeder 7, a magnetic drum roll A 8, a magnetic drum roll B 11 and a stander 12, and is characterized in that a magnet is arranged in an area of about 2 o'clock to 5 o'clock in the rotation direction of a clock and has an angle of 90 degrees in the roll A, a magnet is arranged in an area of about 7 o'clock to 10 o'clock in the rotation direction of the clock and has an angle of 90 degrees in the roll B, the distance between the two rolls is adjustable in the range of 30mm to 100mm, when the twin-roll magnetic separator is in work, the two rolls are driven by the two motors to rotate oppositely, mixed materials to be magnetically separated are uniformly fed above the two rolls, when the loose materials pass through a magnetic field, iron ores with magnetic induction can be adsorbed onto the surface of the magnetic rolls by the magnetic force, and other impurities without magnetic induction fall vertically under the effect of the gravity. In order to prevent the leakage of a minority of iron ores, a distribution stop plate is arranged below a horizontal line between the two rolls and is used for intercepting and delaying the passing time of the fed materials, so that the time of the materials staying in the magnetic field can be prolonged, and the iron ores can be thoroughly recycled.
Description
Technical field:
The invention belongs to the preparation equipment in iron ore dry separation craft.
Background technology:
At present, iron ore is when dry separation, basic employing be magnetic roller type magnetic separation entirely, indivedual adopt upper and lower two rollers to repeat magnetic separation, its operation principle is, according to the needs of output, be rolled into diameter 600 millimeters of-1500 millimeters of cylinders with corrosion resistant plate, length is between 1 meter-4.5 meters, in cylinder about 12 .-5 o'clock of clockwise orientation, be provided with magnet piece, produce magnetic field.Through the iron ore of crusher in crushing and other assorted stone mixture during work, simultaneously to the peak being taped against magnetic roller, the namely place at 12 o'clock, when magnetic roller is in time having the direction in magnetic field to rotate, the material piled up docile can cylinder and then rotation, at this moment there are the iron ore of magnetic strength and other assorted stone can be adsorbed the surface of left magnetic roller by magnetic field simultaneously, when mixed material rotates to below, because gravity, without the barren rock meeting self falling of magnetic strength, and when having the iron ore of magnetic strength can be rotated over field regions by continuation absorption, iron ore comes off again, complete being separated of iron ore and other assorted stone.This operation principle also exists fatal defect: have the iron ore of induction other assorted stone can be bundled together with magnetic field, the assorted stone in just surface be separated, and depend merely on gravity and be wrapped in inner assorted stone and thoroughly cannot be separated with iron ore, so this magnetic separator, magnetic separation effect is not thorough, and yields poorly.
