This routine no medium micron mill is work like this:

Shown in accompanying drawing 2; Driving wheel on the no medium micron mill or shaft joint 33 be rotation at a high speed under the drive of motor; When lump ore class material is fallen by feed hopper 43; At first to pass through pan feeding inner core 54 and then material is evenly distributed on the upper surface of impeller assembly; Because the high speed rotating effect of impeller; Make lump material be able to instantaneous acceleration and under centrifugal action, dish out along the wheel rim tangential direction of impeller with very high linear velocity; And main liner plate 56 high-speed impacts in the pulverizing chamber 64 and bounce-back back and then and other material piece between and and impeller between impact each other, so that is to say under the drive that gets into the high velocity air of lump ore material in pulverizing chamber in the pulverizing chamber each other and and main liner plate between, high-speed friction and bump between the impeller, almost instantaneously just be ground into minimum powder material particle; And then under the drive of eddy airstream, get in the powder feeding chamber 55; Because eddy airstream has simultaneously the effect of cyclone classification again, promptly, so just can the material of the qualified particle diameter among them be sorted out with isodensity particles with different sizes material can just it separately becomes different particle diameter cohorts according to its suffered centrifugal force, running resistance and the difference of climbing power in air stream according to its size; Therefore get into powder material particles in the powder feeding chamber 55 and nearly all be qualified particle diameter; Have once in a while after the entering of big particle diameter because its air that can not afford greater than the gravity of its particle itself brushes the power effect; Thereby this bulky grain material piece can not continue uply can fall on the contrary along the internal cavities in powder feeding chamber 55, then falls again to continue in the pulverizing chamber 64 to obtain pulverizing to reach littler qualified particle diameter up to its particle diameter and can get in the mixed powder chamber 49 through powder feeding chamber 55;

Also but Open valve 13 feeds the ore pulp that pipe 12 constantly feeds outside whole grinding system through the premix ore pulp;, slurry mixing chamber discharges the outside ore pulp of entering system outside the body through discharge pipe 4 immediately after sneaking into dried breeze; The reciprocation cycle of the ore pulp of whole like this ore pulp system through so not stopping just can rise to the pulp density of whole system needed pulp density level and then must think next step and proceed sorting operation and rationally utilize ready; Ease slurry pipe 10 plays the effect of keeping watch on ore pulp face 52 in the slurry mixing chamber 53; After ore pulp face 52 is too high, surpass and just have ore pulp in the setting value ease slurry pipe 10 and overflow; Also can strengthen ore pulp amount that discharge pipe 4 discharges through the ore pulp amount that feeds that feeds pipe 12 through the premix ore pulp and make ore pulp face 52 in the slurry mixing chamber keep being stabilized in to allow in the reasonable range thereby so just can reduce, thereby keep the high-quality and the stable operation of producing through adjustment valve 13; Atomized water feeds and replenishes clear water stablizing with the pulp density that satisfies the whole system in grinding process in pipe 6 and main feed water pipe 7 usefulness the dealing bodies; Guarantee the stable supplying of the interior ore grinding amount of unit interval of whole grinding system simultaneously; For the ore dressing operation of carrying out next step provides a good basic platform; Concrete working order is performed such: the clear water that is fed by main feed water pipe 7 at first gets into annular water chamber 37 and then the bottom in each distributive pipe 36 is sent into the tank 47 in the body; Then the ascending water along with the water level in the tank 47 just flows on the net grid 42 of spray chamber 48 bottoms along the top edge of sink body 51; Simultaneously feed the clear water that has filtered that pipe 6 feeds and at first get into annular conduit 38 by atomized water, and after each shower nozzle 39 atomizings and spray in the spray chamber and then also fallen on the net grid 42; So when machine run, enter the overmulling of flowing through of the air that carries a large amount of pulps slurry mixing chamber in and starch that possibly to have minute quantity when afterwards air is overflowed by the ore pulp face 52 in the slurry mixing chamber 53 wetted and dry powder that become ore pulp is entrained out; Upwards get into spray chamber after getting into the cavity of ore pulp face more than 52 in the slurry mixing chamber 53 then through multilayer net grid 42; In this section process because very fine and closely woven and its surperficial moisture films that has been covered with of sky of netting grid 42; Because the attraction force acts that is produced between ion that dry powder carries and the moisture film ion; Making the dry powder particle be easy to be drawn onto on the moisture film soaks; Also the dry powder particle is caught, soaked and downward flushing action by a large amount of water mist particles of shower nozzle 39 ejections; Therefore the air that gets into spray chamber 48 gets into clear water " cleaning " in the tank 47 and spills into aqueous vapor separation chamber 46 through the water surface then and carry out gas-water separation under the effect of internal body air pressure, the clean air that does not contain the breeze particle then is outside steam vent 5 discharge bodies.
