[specific embodiment]

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to Fig. 1, a kind of vertical centrifugal rolls mill, comprise cylindrical shell 9 and motor 18, cylindrical shell 9 and motor 18 all are installed on the frame 1, on the top of cylindrical shell 9 loam cake 12 is housed, end tube 3 is equipped with in the bottom, the middle part is provided with door 17, be provided with feed hopper 13 on the top of cylindrical shell 9, the bottom of cylindrical shell 9 is provided with discharge bucket, at the discharge bucket place discharging is housed and pulls out charging tray 4, main shaft 15 is equipped with at the middle part in cylindrical shell 9, in cylindrical shell 9, be provided with the two layers of chamber of milling, all be equipped with in the every layer of chamber of milling and grind ball 6, grind rail dish 5, driver chuck 7 and awl liner plate 10 leave the gap between driver chuck 7 and the awl liner plate 10, and every layer dial 7 is to be reduced gradually to lower floor by the upper strata with the gap of awl liner plate 10, spreading disk 16 also is housed in being milled in the chamber on the upper strata, and lower floor mills and pressing spring 8 also is housed on the stone roller ball 6 in the chamber.In the upper and lower of main shaft 15 upper bearing (metal) 14 and lower bearing 19 are housed respectively, the big belt pulley of an end of main shaft 15 2 links to each other with small belt pulley 21 power on the motor 18 by belt 20.

Operation principle of the present utility model is: start motor 18, motor 18 drives main shaft 15 rotations by big small belt pulley and belt 20, main shaft 15 drives discharge port plate, grind rail dish 5, dial 7 and spreading disk 16 rotation at a high speed, 7 fens some lattice of dial, every lattice are put one or more stone roller balls 6, stone roller ball 6 in one deck dial 7 and dial 7 lattice constitutes the chamber of milling, what of chamber of milling are determined by feed size and grinding particle size, undermost stone roller rail dish 5 and a plurality of stone roller ball 6 constitute the chamber of milling of similar rolling thrust bearing, by the grinding pressure of the pressing spring 8 control stone roller balls 6 that grind ball 6, guarantee the material grinding granularity.The stone roller rail dish 5 of rotation promotes to grind ball 6, makes to grind ball 6 one side around centre of sphere rotation, on one side around the revolution of main shaft 15 lines, just moves as a thrust bearing that rolls.Dial 7 promotions of rotation are ground ball 6 and are done the compound movement of spiral along boring liner plate 10 inwalls, because action of centrifugal force makes stone roller ball 6 press to awl liner plate 10 inwalls with tens times of centrifugal force from gravity, and rolls on inwall; At this moment, treat that broken material enters in the vertical centrifugal mill from feed hopper 13, at first drop on the spreading disk 16 of rotation, the spreading disk 16 of rotation is when impacting material, also make material quicken to fly to awl liner plate 10, at this moment the collision of material and awl liner plate 10, material and spreading disk 16, the collision of material and storeroom, the material of bulk is pulverized, dropping to lower floor through the material of coarse crushing mills on the chamber dial 7, because action of centrifugal force, material is got rid of to be attached on awl liner plate 10 inner surfaces, stone roller ball 6 by high speed scroll pulverizes, raw meal particle size is taken up to get rid of once more by dial 7 with the material of boring liner plate 10 gaps greater than dial 7 and is attached on awl liner plate 10 inner surfaces, being ground ball 6 once again, to roll material broken, raw meal particle size is fallen lower floor's dial 7 less than the dial 7 and the material in awl liner plate 10 gaps, material is further rolled pulverizing by the stone roller ball 6 of lower floor, every layer dial 7 is to be reduced gradually to lower floor by the upper strata with the gap of awl liner plate 10, material via the upper strata to lower floor by grind ball 6 roll after the pulverizing raw meal particle size from large to small, fall into the stone roller rail dish 5 of lowermost layer at last, the material that is rolled into qualified granularity by the stone roller ball 6 that pressing spring 8 is housed is fallen end tube 3 by 4 discharges of discharging material toggling dish.The utility model charging maximum particle size is less than 30mm, discharging-material size 20～300 orders.
