The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence; A kind of vibration belt magnetic separator is provided, can handles the big magnetic material of amount after the high-pressure roller mill roll-in continuously, reduce the subsequent technique number of devices; Reduce the process system energy consumption, improve mineral recovery rate and grade.
The technical scheme that the utility model adopts is following:
The vibration belt magnetic separator of the utility model comprises conveyer belt and feed pipe, and the below of said conveyer belt is provided with platform, and said feed pipe is positioned at the end top of platform, and the inboard of said conveyer belt is provided with magnetic system.
Owing to adopted said structure; Fully the material behind the scattering and grading drops on the platform through feed pipe; Material end tail to platform under the gravity effect moves, and ulking thickness reduces gradually, and magnetic material will fully come out; Under the effect of magnetic system, be sorted out and take out of with the transport tape that rotates.Owing to be provided with and be provided with magnetic system in the conveyer belt inboard; Can make magnetic material only be adjacent to conveyor belt surface, thereby make magnetic material take away with conveyer belt, and non-magnetic material moving playing surface to afterbody with platform; Can effectively magnetic material be separated with non-magnetic material
The vibration belt magnetic separator of the utility model; Said conveyer belt comprises magnetic wheel and non-magnetic wheel; Said magnetic wheel is positioned at the end near feed pipe of conveyer belt, non-magnetic wheel be positioned at conveyer belt away from feed pipe one end, the magnetic that said magnetic ties up on the material movement direction strengthens gradually.
Owing to adopted said structure; Magnet pulley is positioned at the end near feed pipe of conveyer belt, and magnetic wheel guarantees that the magnetic material that is sorted out is attracted on the belt, is more conducive to absorb magnetic material in the process of taking out of; And magnetic material is attached on the conveyer belt tightly, be pulled away.Because the magnetic force of magnetic system strengthens along the material traffic direction gradually, make to be wrapped in outer non-magnetic material and to shake off fully in a looping fashion and magnetic ore deposit grade is increased, form concentrate at last and be transmitted and take away.
The vibration belt magnetic separator of the utility model, said platform are shake table, and said conveyer belt is parallel with shake table.
Owing to adopted said structure, be parallel to each other between conveyer belt and the shake table, and the distance between them is adjustable, can set the desired grade of selecting materials easily.Because the magnetic force of magnetic system strengthens along the material traffic direction gradually, make to be wrapped in outer non-magnetic material and to shake off fully in a looping fashion and make the grade increase of magnetic ore deposit, form concentrate at last and be transmitted and take away.Because the magnetic force of magnetic system is constant along the material traffic direction, and the movement locus of concentrate is shortened, and makes the treating capacity of magnetic separator bigger.Shake table can vibrate material; Material can be moved to vibration you tail under the effect of gravity and seismic inertia; Ulking thickness reduces gradually, shares evenly, and magnetic material fully exposes; To be convenient to magnetic be the magnetic material and make magnetic material be close to conveyor belt surface, and be transferred and take away.
The vibration belt magnetic separator of the utility model is 1～45 ° inclined angle alpha between said shake table and the horizontal plane.
Owing to adopted said structure, shake table is horizontal by angle and adjustable angle, and the table top vertical vibration and the amplitude-frequency of shake table are adjustable, can select according to the needs of reality, is fit to different working conditions.The vibration belt magnetic separator of the magnetic material that the amount after the high-pressure roller mill roll-in can handled continuously is big reduces the subsequent technique number of devices, reduces the process system energy consumption, improves mineral recovery rate and grade.
The vibration belt magnetic separator of the utility model, the charging table top of said shake table are provided with the cloth awl.
Owing to adopted said structure; On the charging table top of shake table burden-guiding cone is set, can avoids the local accumulation of material effectively, guarantee that material moves to table top end tail equably; Make the magnetisable material in the material more can be absorbed, and magnetic material and non-magnetic material are separated by magnetic system.
The vibration belt magnetic separator of the utility model, the arranged outside of said conveyer belt has dust catcher.
Owing to adopted said structure, dust catcher can siphon away the non magnetic dust that is wrapped on the magnetic material effectively, can be beneficial to magnetic material is separated with non-magnetic material fully by magnetic separation after making magnetic material exposed.
The vibration belt magnetic separator of the utility model, the arranged outside of non-magnetic wheel have that mine tailing outlet and concentrate export that said concentrate outlet is positioned at that mine tailing exports above.
Owing to adopted said structure, the vibration belt magnetic separator of the utility model can adopt two kinds of conceptual designs; Wherein scheme one is: the transport tape traffic direction is opposite with the material traffic direction; Magnetic is that magnetic force strengthens along the material traffic direction gradually, because the magnetic force of magnetic system strengthens along the material traffic direction gradually, the low slightly magnetic ore deposit of the grade that beginning is not siphoned away strong magnetic area is in the back sucted conveyer belt; Die down gradually along conveyer belt direction of motion magnetic force; Make under the not high ore deposit of grade at weak magnetic area and to drop under the material traffic direction of shake table upper edge, sucted transport tape again, so circulation at strong magnetic area; Parcel non-magnetic material is above that shaken off fully and magnetic ore deposit grade is increased, form concentrate at last and be transmitted and take away; Scheme two: the transport tape traffic direction is identical with the material traffic direction, and magnetic is that magnetic force constant is constant, because magnetic ore deposit movement locus shortens, makes its disposal ability to material bigger.No matter being scheme one or scheme two, all is that magnetic material is taken away from conveyer belt, and promptly magnetic material (concentrate) is taken away from the top all the time; Therefore the concentrate outlet is arranged at the top of conveyer belt tail end; And non-magnetic material moves along shake table all the time, and from its tail end output, therefore the mine tailing outlet is arranged at the shake table tail end; And be positioned at the below, be convenient to mine tailing is taken away.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1. the vibration belt magnetic separator of the utility model, simple in structure, energy-efficient, manufacturing expense is low, and use cost is low, and the equipment operational reliability is high, and maintenance cost is low;
2. the vibration belt magnetic separator of the utility model can conveniently be controlled the grade of concentrate, not only is suitable for choosing of rich ore, also is suitable for choosing of lean ore and extreme poverty ore deposit, can maximally utilise mineral resources;
3. the vibration belt magnetic separator of the utility model can be handled the big magnetic material of amount after the high-pressure roller mill roll-in continuously, reduces the subsequent technique number of devices, reduces the process system energy consumption, improves mineral recovery rate and grade, is beneficial to and applies.
