Abstract
The utility model discloses an abrasion-resistant magnetic roller for a coarse-particle wet type permanent magnet barrel magnetic separator, which comprises a barrel body, a permanent magnet system, an adjusting device (5) of the permanent magnet system and a spindle (4), wherein the permanent magnet system is suspended on the spindle (4) and arranged on the lower portion inside the barrel body, and the barrel body is supported on the spindle (4) through flanges (3) of end covers (2) at two ends of the barrel body. A ceramic abrasion-resistant material layer which is adhered to the surface of the barrel body is formed by splicing ceramic small pieces (1) arranged in lines and columns along the 360-degree circumferential surface of the barrel body. The abrasion-resistant magnetic roller for the coarse-particle wet type permanent magnet barrel magnetic separator can remarkably enhance the abrasion-resistant performance of the surface of the barrel body, and is used for processing coarse-particle materials of 0 mm to 16 mm. The service life of the barrel body of the magnetic separator can be over 6 months.
Description
Technical field
The utility model relates to a kind of cylinder of permanent-magnet drum type magnetic separator, specifically, the wear-resisting magnet drum that relates to a kind of coarse grain Wet-type permanent magnet drum type magnetic separator, the coarse grain Wet-type permanent magnet drum type magnetic separator that is used for material handling granularity 0～20mm, particularly 0～16mm can significantly improve the anti-wear performance of magnetic separator cylindrical shell.
Background technology
According to statistics, when the magnetic iron ore ore grain size was crushed to the 10mm left and right sides, existing about 10%～30% gangue mineral monomer dissociation can be used as the qualified tailings throwing and removes.But when utilizing existing dry type magnet drum that this grade ore is sorted,, be difficult to obtain the useless effect of desirable throwing because of feed particle size is thinner.If it is useless to adopt wet magnetic separation to throw to the ore of this part 10～0mm grade, will improve greatly and throw useless effect, this is because wet magnetic separation is different with dry type magnetic separation mechanism.
Conventional general fine-graded ore of suitable treatment 3～0mm of wet magnetic separator, if adopt common magnetic separator to carry out the preliminary election of wet type coarse grain, because of reasons such as cylindrical shell magnetic signature, cylindrical shell anti-wear performance and trough body structures, can cause situations such as the efficiency of separation is low, mine tailing Armco magnetic iron loss late is big to take place, especially cylindrical shell serious wear, service life is low.Therefore, for adapting to this new specification requirement, be necessary coarse grain permanent magnetic wet type magnetic plant is carried out research and development.
The coarse grain wet magnetic separator is different with common magnetic separation, and the ore grain size of sorting is big, work under bad environment, and domestic a lot of mines disintegrating apparatus falls behind, all outmoded, ore grain size is often lost control of, and has more aggravated the wearing and tearing of tube table, the ore thickness is mingled with mutually, the extruding cylindrical shell of easily reuniting, scraping tube table.Give the very big requirement of wear-resisting proposition of drum surface.For alleviating the wearing and tearing of tube table, means commonly used are at the additional one deck high-abrasive material of drum surface such as rubber, polyurethane etc., but still can not satisfy the requirement greater than 6 months cycles service life.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above that exist at prior art, and the wear-resisting magnet drum of the coarse grain Wet-type permanent magnet drum type magnetic separator of a kind of simple in structure, wearing layer materials processing and effective, long service life easy for installation, wear-resisting is provided.
For realizing above-mentioned purpose of the present utility model, the wear-resisting magnet drum of a kind of coarse grain Wet-type permanent magnet drum type of the utility model magnetic separator by the following technical solutions:
The wear-resisting magnet drum of a kind of coarse grain Wet-type permanent magnet drum type of the utility model magnetic separator is to be made of cylindrical shell, permanent magnetic system and adjusting device thereof, main shaft, permanent magnetic system hangs on the main shaft and is built in the bottom of cylindrical shell, and cylindrical shell is supported on the main shaft by the flange of two ends end cap.Be characterized in that at the bonding one deck ceramic wear-resisting of drum surface material layer described ceramic wear-resisting material layer is to be spliced to form according to row, column along 360 ° of circumferential surfaces of cylindrical shell by ceramic small pieces.
The specification of described ceramic small pieces is length * wide * thick=8～12 * 8～12 * 2～4mm, is good with 10 * 10 * 3mm.
The pottery small pieces are to adopt the high strength bonding agent to be bonded on the drum surface.
After the wear-resisting magnet drum of a kind of coarse grain Wet-type permanent magnet drum type of the utility model magnetic separator adopts above technical scheme, can significantly improve the anti-wear performance of drum surface.Checking result by industry test in 3 months shows: handle the coarse-grained material of 0～16mm, through 3 months running, potsherd thickness reduced to 2.8mm by 3.0mm, had only reduced 0.2mm.From this result, estimate that the magnetic separator cylindrical shell can reach more than 6 months service life, reached the requirement of setting.
