Field dry-dressing machine.
Background technique
Currently, there are two types of the dry-dressing machines that magnetic iron ore dry type magnetic separation generally uses: one is " magnetic pulleys ", i.e. a magnetic separation rolling
Great wheel as travelling belt uses, and drives travelling belt movement.The grading principle of magnetic pulley is: magnetite ore passes through magnetic separation
When rolling, make level throw motion, by the magnetic mine of magneticaction, by the lesser weak magnetic mineral of magneticaction and not by magneticaction
Nonmagnetic gangue leaves track difference, thus drop point is different, so being separated.Although magnetic pulley structure is simple, just like
Lower disadvantage: sharpness of separation is poor when ore grain size is larger, is easy to run mine, dry separation tailings grade is higher；The ore grain size smaller time-division
Select precision also poor, tailing separation is insufficient in dry separation concentrate, and dry separation concentrate grade is relatively low.Another dry-dressing machine is that " outstanding magnetic is dry
Select machine ", i.e., dry separation magnetic system top that magnetic mine Ore Transportation belt is arranged in, outstanding magnetic dry separator are suitable for handling the magnetism of particulate
Mine, by the magnetic mine on travelling belt be attracted to top hang magnetic dry separator during, than magnetic pulley graded shot magnetism mine
Effect it is much better, but since most of magnetic-particle is the outstanding magnetic dry separation for being disposably drawn onto top from travelling belt
On machine, some non-magnetic particles can also sweep along the dry-dressing machine that top is drawn between magnetic-particle, therefore also have tailing separation
It is insufficient, the relatively low problem of dry separation concentrate grade.

Afterwards, it between downlink belt and uplink belt and sticks on downlink belt, it is characterised in that: the dry separation magnetic system is by non-magnetic
Property material production cuboid box, the basic magnetic system that is arranged in cuboid box and the multistage enhancing being superimposed on basic magnetic system
Magnetic system is formed, and the cuboid box and fortune barrow band are wide, and one end of length is located at fortune left side of the barrow with head pulley, separately
One end is located at fortune right side of the barrow with head pulley；The magnetic field strength of the dry separation magnetic system is along dry separation belt direction of travel staged
Enhancing.
The multistage enhancing magnetic system is 3~5 grades of enhancing magnetic systems.
The magnetic field strength of the basic magnetic system is 5000Gs~6000Gs, after the basic every superposition level-one enhancing magnetic system of magnetic system
The magnetic field strength of the dry separation magnetic system of the enhancing magnetic system position is incremented by by 1000 Gs~1200Gs amplitude.
The dry separation magnetic system is permanent magnetic system or electromagnetism magnetic system.
The fortune mine belt feeder and dry separation belt feeder reverse direction operation.
The utility model has the advantages that:
The characteristics of the utility model is enhanced using the magnetic field strength of dry separation magnetic system along dry separation belt direction of travel staged, if
A kind of ladder magnetic field dry-dressing machine is counted, the dry-dressing machine for avoiding single magnetic field strength disposably attracts in raw ore showing for magnetic mine particle
As a point multiple batches of magnetic mine particle by raw ore is attracted to dry-dressing machine, to reduce magnetic mine particle to non magnetic mine particle
It sweeps along and carries secretly, more fully separate magnetic mine particle and non magnetic mine particle, improve dry separation effect.
