Abstract
The utility model discloses a double-cylinder counter-pole type permanent-magnet strong magnetic dressing machine which belongs to an ore dressing device. The utility model is suitable for mine mill selection for wet magnetic dressing work and is characterized in that double rolling drums are used for ore dressing and the scallop-shaped permanent magnetic systems in the two rolling drums form counter poles in the horizontal direction to make the magnetic circuit in the form of semi-closure and semi-open to achieve the purposes of increasing the magnetic intensity and improving the dressing effect, and an ore tailing weir plate is arranged under the gap between the two rolling drums to further improve the dressing effect. The utility model has the advantages of high magnetic intensity, low cost, favorable dressing effect, large treating capacity, no blockage, low power consumption, and convenient operation and maintenance. The double-cylinder counter-pole type permanent-magnet strong magnetic dressing machine is suitable for weakly magnetic ore dressing and can be used for the whipping work of strongly magnetic ore.
Description
The utility model belongs to preparation equipment.
Advantages such as treating capacity is big, sorting result good, power consumption is little though the permanent-magnet drum type magnetic separator of present domestic use has, convenient operating maintenance, but this magnetic separator all is an opening magnetic system, magnetic field intensity is low, belong to low-intensity magnetic field or middle magnetic field magnetic separator, only be applicable to sort strongly magnetic mineral and roasted ore.China's mine weak magnetic mineral is more, sorts the at present electromagnetic type intensity magnetic separators that adopt of such mineral more.But electromagnetic type intensity magnetic separator cost height, power consumption is big, and operation and maintenance are complicated, the susceptible to plugging problem of ubiquity separatory vessel medium.
The purpose of this utility model provides and a kind ofly is applicable to twin-roll that wet type sorts weak magnetic mineral to the polar permanent magnetic intensity magnetic separator, and these facility have the magnetic field intensity height, and cost is lower, treating capacity is big, and sorting result is good, and power consumption is little, do not stop up, simple to operate, advantage such as easy to maintenance.Be applicable to sort weak magnetic mineral, also can be used for the whipping operation of strongly magnetic mineral.
For achieving the above object, this machine is provided with two cylinders, and a fan-shaped permanent magnetic system is arranged in each cylinder, and it is relative that two fan-shaped magnetic ties up to the horizontal direction magnetic pole, forms the semi-open magnetic loop of semi-closed.Available so less magnetic material obtains very high magnetic field intensity.An arc mine tailing of installation weir plate below two cylinder gap, prolongation sorts band, further improves sorting result.
Accompanying drawing 1 is the twin-roll that the utility model proposes structural representation to the ore dressing part of a kind of embodiment of polar permanent magnetic intensity magnetic separator.Among the figure: 1 cylinder, 2 fan-shaped permanent magnetic systems, 3 yokes, 4 give ore deposit case, 5, mine-carrying groove, 6 mine tailing weir plates, 7 mine tailing mouths, 8 concentrate mouths, 9 dividing plates, 10 wash tub pipes
Describe details of the present utility model and ore dressing process in detail below in conjunction with accompanying drawing.
Twin-roll to the ore dressing of polar permanent magnetic intensity magnetic separator part by two cylinders (1), two fan-shaped permanent magnetic systems (2), two yokes (3) are given ore deposit case (4) and mine-carrying groove compositions such as (5).Mine-carrying groove is again by two mine tailing weir plates (6), two mine tailing mouths (7), two concentrate mouths (8), two dividing plates (9) and four wash tub pipe compositions such as (10).
Two cylinders (1) and inner fan-shaped permanent magnetic thereof are that (2) level is installed on the frame, and by bearings.Two cylinders (1) are rotated along the arrow direction by separately motor and transmission system drive respectively, and permanent magnetic system (2) maintains static.Leave certain clearance between two cylinders.Face gap between two cylinders for the feed port of ore deposit case (4).Fan-shaped permanent magnetic system (2) is made up of several magnetic groups and is fixed on the yoke (3), and the polarity of each magnetic group is alternately arranged at circumferencial direction NS, and it is relative that the interior magnetic of two cylinders ties up to horizontal direction NS, is called the utmost point.Magnetic in such two cylinders just forms the plurality of closed magnetic loop near tying up to two centre of the drum's lines, therefore the powerful big raising of ambient field at two cylinder gap places.For example magnetic material adopts neodymium iron boron, and two cylinder minimum clearance places and near field intensity thereof can reach 600mT～1000mT.Two cylinders can move horizontally within the specific limits, regulate the gap between two cylinders, obtain different magnetic field intensities, and field intensity descended when the gap was big, but the treating capacity increase, gap hour field intensity improves, but treating capacity reduces.The effect of arc mine tailing weir plate (6) is: prevent that magnetic mineral from coming off owing to acceleration of gravity prolongs vertical direction; Change the ore pulp flow direction, reduce flow rate of pulp, make it fully to be sorted; Ore pulp is approached cylinder, and increase sorts length and magnetic rolling number of times, improves sorting result.
Ore dressing process of the present utility model is as follows: cylinder (1) rotates in the drive lower edge of motor and the transmission system direction of arrow, ore pulp is by flowing down for ore deposit case (4), strongly magnetic mineral just was attracted on the cylinder surface and was brought to concentrate before no show high-intensity magnetic field district and unloads the mining area, weak magnetic mineral and non magnetic ore continue dirty, when flowing to the high field intensity district, most of magnetic mineral is adsorbed on the cylinder surface and is brought to concentrate and unloads the mining area, small part magnetic mineral and non magnetic ore are approached cylinder by the mine tailing weir plate, near magnetic system, and continue to flow down along the gap between mine tailing weir plate and the cylinder, magnetic mineral continues to be attracted on the cylinder surface, and repeatedly magnetic rolling gets rid of non magnetic ore.Non magnetic ore is discharged from mine tailing mouth (7), and magnetic mineral is taken to concentrate by cylinder and unloads the mining area, breaks away from cylinder and discharge from concentrate mouth (8) under the flushing of wash tub pipe (10).The effect of dividing plate (9) is to prevent that concentrate and tailings from mixing the ore deposit.For concentrate is rinsed well, each cylinder washes with two wash tub pipes.The continuous like this ore deposit of giving, refined ore constantly is adsorbed on the cylinder surface and is brought to and unloads the mining area, is rinsed water and sweeps away, and mine tailing is constantly discharged from the mine tailing mouth, thereby finishes continuous ore-dressing practice.
Claims (2)
1, a kind of twin-roll belongs to preparation equipment to the polar permanent magnetic intensity magnetic separator, has two cylinders, and each cylinder inside all is equipped with fan-shaped permanent magnetic and is; Be equipped with to the ore deposit case in two cylinder gap upper end, the mine-carrying groove of arc mine tailing weir plate is housed below, two mine tailing mouths and two concentrate mouths are housed in the mine-carrying groove bottom, concentrate mouth and mine tailing mouth are separated by two dividing plates, two concentrate mouth upper ends two wash tub pipes are housed respectively, it is characterized in that the interior fan-shaped permanent magnetic of two cylinders ties up to horizontal direction and forms the utmost point, making magnetic circuit is the semi-open form of semi-closed.
2, twin-roll according to claim 1 is characterized in that arc mine tailing weir plate is housed below two cylinder gap to the polar permanent magnetic intensity magnetic separator, leaves certain clearance between this weir plate and the cylinder.
