Screening plant, screening plant include flase floor 14 and swash plate 15, and flase floor 14 tilts down, and swash plate 15 is with flase floor 14 in certain
Angle is set, and drain spout 16 is set in the side wall 8 between swash plate 15 and flase floor 14, sets wire to keep off door in drain spout 16
12, outer tunnel 17 is set in the side wall in the outside of drain spout 16, ore passage is formed between swash plate 15 and next group of flase floor 14
18；Cooling device 3 includes shell 19, and shell is provided with cooling device entrance 20, conveyer belt 21, conveyer belt 21 are provided with shell 19
Top sets multiple water injectors 22, and the rear of water injector 22 sets blowing device 23；Second heating apparatus 4 are arranged on cooling dress
Put 3 top of conveyer belt 21, second heating apparatus 4 include metal shell and the second microwave generator 24, close on metal shell
Reheating entrance 26 and reheating outlet 27 are set on the position of conveyer belt 21, and reheating entrance 26 and reheating go out
Wire is set to keep off door 12 on mouth 27.
The method that ore treatment is carried out using the microwave mineral processing system of the present invention is comprised the following steps, by lump ore
The fritter ore of the size of suitable subsequent step processing is broken into, typically less than 8cm, fritter ore is imported into carry out first
Secondary microwave is heated, and screening plant is set in first time microwave heating equipment, and the time that the ore of bulk is heated is longer, fritter
Ore discharged in time from heater.Suitably heated ore enters to spray water cooling, utilizes microwave heating and cooling water
The temperature difference caused by cooling, make to produce the deformation expanded with heat and contract with cold inside ore, improve the automatic rupture inside ore so that ore
Internal texture changes.Ore after spraying cooling is dried up the moisture of mineral surface by drying, then by ore
It is sent into second of microwave heating box and carries out second of heating, the ore after heating is sent into crush box and crushed.
Lump ore enters broken case 1, is heated after preliminary crush as less stone into heater box 2, heater box 2
Entrance 10 and outlet 11 keep off door 12 by being arranged on the wire of a both sides and block electromagnetic wave and prevent from leaking, ore enters heating
Rolled after case 2 on inclined flase floor 14, less ore is leaked down by flase floor 14, and larger ore is along flase floor
14 roll down to next layer, and the small ore for falling on the lower section of flase floor 14 rolls out heater box along swash plate 15 from drain spout 16, larger
Ore can continue to scroll down through along swash plate 15, continue to be heated with microwave.Next layer of flase floor interval is big by 15%, ore rolling
To after next layer of flase floor 14, secondary a little bit smaller ore will be fallen from the gap of next layer of flase floor 14, from material leakage
Mouth 16 leaves heater box 2.
In the heating process to ore, ore absorbs microwave and produces high temperature microwave, is begun to warm up from inside.Utilize microwave
Heating ores, the heating rate of ore is fast, can quickly be raised to treatment temperature, improves the treatment effeciency of ore.In ore not
The difference of congruent microwave absorbing property, dilatancy and heating rate, the effect of thermograde between different minerals composition be present, lead
Cause to produce larger thermal stress inside ore particles, had differences plus the thermal coefficient of expansion of various mineral, cause ore particles
Inside produces crack.
Want the absorption for making ore obtain enough just right energy to microwave of crackle needs.If lump quilt
The overlong time of heating, some positions of ore are easier to absorb the energy of microwave, and temperature rises too high, and it is anti-that chemistry easily occurs
Should, the time that small stone needs heat is short, and the heating that big lump takes longer for.If continuously applying microwave,
The particle must avoid over-exposure while still obtain required rapid local heating and micro- readily through microwave field
Crackle.
Using the heater box of the present invention ore of the small volume residence time in heater box can be made shorter, can obtained
To appropriate amount of energy.Ore rolling flip on the slope in heater box, it is ensured that the different directions of ore are uniform
Receive the energy of microwave.Structure as heater box can ensure different size ore homogeneous heating of different shapes, prevent
Heat or underheat.
Heater box outlet 11 is docked with cooling device entrance 20, enters cooling device 3, ore by the ore suitably heated
Moved along conveyer belt 12, by the spraying cooling water of water injector 22, using the temperature difference caused by microwave heating and cooling water temperature,
Make to produce the deformation expanded with heat and contract with cold inside ore, improve the automatic rupture inside ore so that the texture inside ore becomes
Change.Conveyer belt 12 is metal mesh belt, and cooling water and small ore particles leak down from the hole of guipure to the pond 30 of lower section
In, pond side sets bypass outlet 29, and ore particles are discharged from bypass outlet 29.Ore after spraying cooling is defeated
Send and the lower section of blowing device 23 is continued to move on band 12, blowing device 23 dries up the water of mineral surface.Ore is in conveyer belt 12
It is upper that second heating apparatus 4 are entered by reheating entrance 26.Conveyer belt 12 can select wire netting conveyer belt.
Water has been infiltered in into the crack inside the ore of second heating apparatus 4, and the moisture of outer surface is dried, now
The texture of ore and the absorption reflection characteristic to microwave have greatly changed once more in the presence of water, in ore gap
Water expanded in the presence of microwave in addition seethe with excitement, cause originally be insufficient to allow ore rupture minute crack further expand,
So that subsequently the crushing to ore is easier.
Ore through secondary microwave heating enters in crush box 5, and pulverization roller 28 in crush box 5 is by the further powder of ore
It is broken.
