Description
Technical field
The utility model relates to a kind of wet type coarse grain permanent-magnet drum type magnetic separator.
Background technology
The ore dressing plant is the energy consumption rich and influential family of bargh.General iron ore beneficiating factory energy consumption accounts for 83% of bargh's energy consumption.And the energy consumption of grinding operation accounts for 50% of ore dressing plant energy consumption.So dissociating, early throw tail the morning in ore-dressing practice, early reclaiming is to create the best good method of technical-economic index.See that with regard to present development trend the disposal ability of existing big specification magnetic separator also dislikes not enough in mammoth mill.Particularly the expansion of ore dressing plant scale and the large-scale maximization that turns to sorting equipment broken, grinding attachment have proposed requirement.The large-scale wet-type pre-selection device of development major diameter long cylindrical shell can before going into to grind prerequisite, dish out a part of gangue, country rock.Make into the mill grade and improve 3～6% percentage points.Can realize the ore dressing new concept of " many broken few mills ".Reduce and go into to grind intensity.Comminution energy conssumption is than low many of power consume, thereby reaches the energy-saving and emission-reduction consumption reduction.Have tangible economic benefit and social effect.
Summary of the invention
The long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator purpose is exactly for solving the above-mentioned problems in the prior art, and provide a kind of wear-resistant, coarse granule high throughput to sort, stable and reliable operation, energy-saving and emission-reduction consumption reduction, the novel magnetic plant that unit occupied area is few, operation cost is low.
In order to achieve the above object, the utility model major diameter, long cylindrical shell coarse grain permanent-magnet drum type magnetic separator are like this designs: ore deposit case 1, cell body 2, wear-resistant rubber sheet 3, permanent magnetism cylindrical shell 4, the two fulcrum gear drives 5 of axis, magnetic are 6 to this magnetic separator by giving, concentrate case 7, frame 8 etc. constitute.Cell body adopts half adverse current form, adopts with the ore pulp contact-making surface and pastes wear-resistant rubber sheet, improves the wearability of cell body; Disposed deep slot type half adverse current cell body, cooperated and adopt big cornerite magnetic to be, 8 field structures, magnetic pole is alternately arranged, and the magnetic ore particle is strengthened at the magnetic rolling of drum surface; (Φ 1500 * 4500mm), sort the existing drum magnetic separator (diameter of phi 1050mm) of band and prolong 43% to adopt large-diameter cylinder body; Adopt the two fulcrum gear drives of straight-through axle, solving the long cylindrical shell coarse grain of major diameter permanent-magnet drum type magnetic separator magnetic is overweight problem, makes the complete machine running steadily reliable.
Compared with prior art, following advantage is arranged after the long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator employing technique scheme:
1, owing to adopt the abrasive rubber cell body, the wearability of cell body is improved exponentially.Reduce servicing time, improved the operating rate of equipment, reduced operating cost.
2, permanent-magnetic cylindrical cylindrical shell rotary power drives by tube end cap limit gear wheel direct connection.The permanent-magnetic cylindrical main shaft is no bearing shell, straight-through axle form, and the magnetic system of several tons of weights is directly dropped on the frame spindle drum by main straight-through axle.This structure magnetic separator permanent-magnetic cylindrical indeformable, stressed good, the running smooth and easy reliable and stable.The long cylindrical shell magnetic separator of major diameter magnetic system is than the heavily about twice of magnetic system of existing magnetic separator, tradition permanent-magnetic cylindrical cylindrical shell rotary power is attached to the cylindrical shell end cap by semiaxis or brasses axle form, overweight magnetic is that stress point drops on the support axle bed indirectly by semiaxis or brasses axle form, its cylindrical shell bearing and bearing shell are easy to wear, and causing magnetic is that integral body comes off.
3, structure such as the big disk pack of small curvature radius angle many magnetic poles opening magnetic system increases the depth of interaction in magnetic field, helps the realization of coarse grain, high throughput.
4, adopt large-diameter cylinder body, sort the existing drum magnetic separator (diameter of phi 1050mm) of band and prolong 43%.More help sorting of magnetic mineral.
Description of drawings
For further describing the utility model, the long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator is described in more detail below in conjunction with accompanying drawing and example.
Fig. 1 is the long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator structure chart.
Fig. 2 is the two fulcrum gear drive figure of the straight-through axle of the utility model.
The specific embodiment
By the long cylindrical shell coarse grain of the utility model major diameter illustrated in figures 1 and 2 permanent-magnet drum type magnetic separator figure as can be seen, the long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator is that ore deposit case 1, cell body 2, wear-resistant rubber sheet 3, permanent magnetism cylindrical shell 4, magnetic are 6 by giving, frame 8 etc. constitutes.Disposed deep slot type half adverse current cell body, cooperated and adopt big cornerite magnetic to be seven field structures.Magnetic pole N, S alternately arrange, and the magnetic ore particle is strengthened at the magnetic rolling of drum surface.(Φ 1500 * 4500mm), sort the existing drum magnetic separator of band and prolong 43% to adopt large-diameter cylinder body.Because radius of curvature increases, more help sorting of magnetic mineral simultaneously.The increasing of distance between two poles improves the magnetic field depth of interaction.The utility model is because above-mentioned improvement has improved the processing granularity upper limit (10～0mm).The deep trouth body has washings at the concentrate outlet side, thereby increases substantially concentrate grade.Easily reject gangue and the lean intergrowth that is mixed in therebetween, improve the operation concentrate grade; The magnetic induction intensity height helps improving the magnetic mineral rate of recovery.Cell body 2 adopts half adverse current form.Adopt stickup wear-resistant rubber sheet 3 with the ore pulp contact-making surface, have anti-wear performance preferably.Permanent magnetism cylindrical shell 4 rotary powers drive by cylindrical shell travelling gear 10.The permanent-magnetic cylindrical main shaft is formed no bearing shell form by straight-through axle 9, the two fulcrum gear drives 5 of straight-through axle.Making cylindrical shell and magnetic is that weight directly drops on frame 8, the axle bed 11 by main shaft.Guarantee the stable long-term running continuously of magnetic separator.
The long cylindrical shell coarse grain of the utility model major diameter permanent-magnet drum type magnetic separator is the specific susceptibility according to various different minerals, utilizes magnetic force and mechanical force to carry out sorting mineral.When ore pulp by the branch constituency of entering cell body 2 for ore deposit case 1, because various mineral specific susceptibility differences, under the magneticaction of magnetic field, strongly magnetic mineral is attracted on the drum surface, take the concentrate gape to the cylinder rotation, after the disengaging magnetic system, enter concentrate case 7 by the concentrate flushing water; Gangue and weak magnetic mineral are owing to a little less than the magnetic, can not under the effect of flow of slurry, be scanned district's gravity flow through mine tailing and enter mine tailing ore discharge pipe in cell body by magnetic attraction.
