Embodiment 1

[0042] High gradient magnetic gathering medium of the present invention (see Figure 5 ) is used on XCSQ50×70 and double-ring magnetic separators, including non-magnetic metal plates 6 and magnetic medium rods 3, and the medium rods are riveted between two non-magnetic metal plates 6 to form a size suitable for the separation chamber of the magnetic separator. Sorting medium box, diamond-shaped magnetic-conductive medium rods are vertically riveted between two non-magnetic-conductive metal plates at a density of 50%, the length-to-width ratio of the two diagonals of the diamond-shaped cross-section is 2:1, and the lengths of the two diagonals of the rhombus-shaped cross-section are respectively 10mm and 5mm, the two top corners (acute corners) of the dielectric rod are rounded by R2mm.

[0043] Figure 5 Among them, the separation magnetic field space of the magnetic separator is the cross-sectional gap between the magnetic pole 1 (N) and the magnetic pole 1 (S) in the figure...

Abstract

The invention discloses a novel high-gradient magnetic flux converging medium for a high intensity magnetic separator. The high-gradient magnetic flux converging medium comprises non-magnetic conducting metal plates and a magnetic conducting medium rod, wherein a cross section of the magnetic conducting medium rod has a shape of equilateral rhombus; the rhombic magnetic conducting medium rod is fixed between the two non-magnetic conducting metal plates, thereby forming a separating medium box; the two non-magnetic conducting metal plates are embedded into a separating space of the magnetic separator in a parallel mode and are in suitable size; and two long-end vertex angles (acute angles) of the equilateral rhombic magnetic conducting medium rod are subjected to chamfering treatment. The high-gradient magnetic flux converging medium provided by the invention has the advantages that a gradient of a magnetic field in a magnetic path is high, magnetic resistance is small and energy consumption is saved; the high-gradient magnetic flux converging medium has the advantages of being free from 'magnetic short circuit' phenomenon and being difficult to block during an ore grain recycling process; and the high-gradient magnetic flux converging medium is specially suitable for recycling fine weak-magnetic ore grains and an effective grain level recycling lower limit can reach 5 microns.

Description

technical field [0001] The invention relates to a high-gradient magnetic-gathering medium used in a strong magnetic separator, which belongs to the mineral processing field in mining and metallurgy engineering mineral processing engineering. Background technique [0002] Now strong magnetic iron ore and high-quality iron ore resources are decreasing day by day, and the iron ore resources faced by mining, metallurgy, engineering and iron ore dressing are mainly hematite, limonite and siderite, which are fine, poor and magnetic. Very weak iron ore resources, the key technology to effectively recover these iron ore resources is to use high-gradient strong magnetic separators. [0003] High-gradient strong magnetic separator is a very important mineral processing equipment in the iron and steel industry of mining and metallurgy engineering. Its quality directly affects the utilization rate of iron ore resources, the economic benefits of the mineral processing plant, the energy s...
