Description
Technical field
The utility model is a kind of ore dressing industry particulate, desliming screening installation, specifically is to be drench pit to containing a kind of novel permanent magnetic tower ring magnetic that the bigger magnetic iron ore of mud improves the concentrate product.
Background technology
The tradition magnetic dewater cone is divided into two kinds of permanent magnetism drench pit and electromagnetism drench pits by the magnetic source difference.Magnetic dewater cone has running gear simple in structure, no, easy to operate, do not consume power, treating capacity reaches advantages such as separation index is good greatly.Therefore magnetic dewater cone is widely used in and concentrates magnetite concentrate before choosing divides fine-grained magnetite and filtration.In stage grinding and stage grading technology,, can remove the mine tailing of some with the roughing separation equipment of magnetic dewater cone after as primary grinding.Generally also be used for preceding desliming of magnetic separation or conduct sorting equipment in advance.
Magnetic dewater cone is the symphyogenetic preparation equipment of magnetic force and gravity.At magnetic dewater cone middling particle gravitate and to the bottom land sedimentation, the magnetic ore particle also is subjected to magneticaction, and point to the high place of magnetic field intensity; Also be subjected to the effect of the impulse force of ascending current generation in addition, it hinders the ore particle sedimentation on the one hand, makes non magnetic fine fraction gangue and sludge enter overflow, makes the magnetic mine particle group of the poly-chaining of magnetic loose simultaneously, the gangue that is mingled with is wherein developed, thereby improve concentrate grade.
The operation of magnetic dewater cone mainly is a size of adjusting the rising water yield and gape.In order to make magnetic ore particle and non magnetic ore particle gangue and sludge obtain sorting well, the upthrust that should make ascending current is less than the magnetic force and the gravity sum that act on the magnetic ore particle, and greater than the gravity that acts on non magnetic fine-grained gangue and sludge.The magnetic ore particle upthrust that overcomes ascending current is deposited to bottom land like this, and discharges from bottom land.Non magnetic fine-grained gangue overcomes gravity and enters overflow with ore pulp then under the ascending current effect.
The operation of permanent magnetism drench pit mainly is exactly a size of adjusting the rising water yield and gape, obtains separation index preferably in order to make drench pit, especially will note the influence of ascending current to its work, guarantees that ore pulp flows steadily in the groove, not magic flower.The effect of ascending current is that gangue in the ore pulp and sludge are washed away.The power (magnetic force+gravity) that acts on the magnetic ore particle should be greater than the impulse force of ascending current, and the impulse force of ascending current must be greater than the mechanical force (mainly being gravity) that acts on the non magnetic ore particle.Therefore the size of ascending current must be suitably.When ascending current was too big, the magnetic ore particle entered overflow easily, phenomenon of turning over flower occurs, and tailings grade is raise, and magnetic metal runs off big, if ascending current hour, non magnetic ore particle is difficult for wash away among sneaking into concentrate, makes the concentrate grade reduction.
At ascending current one regularly,, then can reduce the concentration that concentrate is discharged, sneak into sludge easily in the concentrate and reduce concentrate quality if gape is too big.Otherwise,, separation index is degenerated if gape is too small.
This shows that the quality that the drench pit operation is adjusted has crucial influence to separation index.But in the actual production process, operation is adjusted untimely phenomenon and is also often taken place, and drench pit magic flower and high also the happening occasionally of overflow tailings grade are inevitable.
The magnetic system of conventional dehydration groove is designed to tower magnetic system, the magnetic field intensity of downflow weir very a little less than, the magnetic deviation that regional in this section magnetic ore particle and non magnetic ore particle are subjected to is apart from very little, ore particle can only carry out sorting by gravity as long as arrive this regional ore particle, as long as the impulse force of ascending current is greater than the gravity of ore particle, the magnetic ore particle also will be poured overflow becomes mine tailing, and especially for containing the bigger magnetic iron ore of mud, the metal loss that causes is even more serious.
