Abstract

The utility model discloses a multistage ring ball flour mill for pulverizing ore. A machine casing and a lower bearing seat are arranged on a machine seat of the utility model, an upper bearing seat and a feed hopper are arranged on a machine cover, the lower part of a rotary shaft is provided with a triangular band wheel, a milling cylinder is arranged in the machine casing positioned between the machine seat and the machine cover, the rotary shaft at the center of the milling cylinder is sheathed with a balk cargo disk and a milling disk core sleeve which is provided with a milling disk, each of milling balls which are arrayed in a round ring is positioned on the middling disk and is positioned in a rolling way of the inner circle of the grinding cylinder simultaneously. The utility model can work singly to pulverize ore and can match an air current powder selecting machine to pulverize ore too.

Description

Multistage global flour mill

The utility model relates to a kind of multistage global flour mill that is used for powder ore.

In the prior art, as Peter's Si flour mill of Si Bidesi joint stock corporation (Claudius PetersJoint Stock Co.) at the bottom of the Hamburg, Germany gram labor.In the mill chamber of this flour mill, the abrading-ball of pressing the toroidal arrangement does not fall down from the slit between lower millstone and housing in order to guarantee crushed stone between the lower millstone of fixing upper millstone and rotation, must be equipped with the close air blast of power with flour mill.Therefore, the system energy consumption of this flour mill is bigger, and on the other hand, because this flour mill is subjected to the restriction of centrifugal force, rotating speed is lower, and so the essential gear reduction unit that is equipped with is the manufacturing cost height of this flour mill.

The purpose of this utility model is that a kind of novel multistage global flour mill will be provided, and it has advantages such as the low and low cost of manufacture of system energy consumption.

The purpose of this utility model is achieved in that this multistage global flour mill that is used for powder ore, casing 11 and step 15 are installed on the support 12 of this flour mill, top chock 1 and loading hopper 3 are installed on the cover 4, vee-pulley 16 is equipped with in the bottom of rotating shaft 5, be characterized in: in the casing 11 between support 12 and cover 4 mill tube 10 is housed, be positioned at and be set with bulk cargo dish 6 and mill core retainer plate 9 in the rotating shaft 5 at mill tube 10 centers, mill 8 is housed on the mill core retainer plate 9, each abrading-ball 7 of arranging by toroidal both had been positioned on the mill 8, also was positioned at the raceway of mill tube 10 circles simultaneously.

The utility model can be achieved in that also the abrading-ball of arranging by toroidal 7 encircles and the quantity of mill 8 all should be 2～5.

The novel of this practicality can also be achieved in that mill tube 10, abrading-ball 7 can be steel with the material of mill 8, also can be ceramic.

The utility model with the advantage that Peter's Si flour mill of the prior art is compared is:

1, when abrasive dust, discharging opening of the present utility model is communicated with the negative pressure inlet pipe of air-flow powder concentrator, because the diameter of air inlet pipe is smaller, so, only need just the thickness powder of pulverizing together can the be made a gift to someone disengagement chamber of powder concentrator of 1/3 air blast of flour mill power, therefore, its system energy consumption is low.

2, under the identical situation of production capacity, the utility model is simple in structure, volume is little, because it belongs to medium rotating speed, can be slowed down through the one-level vee-pulley by motor gets final product, and does not need gear reduction unit, so the utility model low cost of manufacture.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the profile (part that wherein is sleeved in the rotating shaft does not cut open) according to the multistage global flour mill that the utility model proposes.

Number in the figure is represented:

1, top chock 2, charging aperture 3, loading hopper 4, cover

5, rotating shaft 6, bulk cargo dish 7, abrading-ball 8, mill

9, mill core retainer plate 10, mill tube 11, casing 12, support

13, material scraping plate 14, discharging opening 15, step 16, vee-pulley

The utility model is described in further detail below in conjunction with accompanying drawing.

Top chock 1 and loading hopper 3 are installed on the cover 4, step 15 is installed on the support 12, be connected in the casing 11 between support 12 and the cover 4 mill tube 10 is housed, be positioned in the rotating shaft 5 at mill tube 10 centers and be set with bulk cargo dish 6 regularly, mill core retainer plate 9 and vee-pulley 16, frictionally drives abrading-ball 7 raceways of circle in the mill tube 10 and rolls when being contained in mill 8 on the mill core retainer plate 9 with rotating shaft 5 rotation, the lump material that needs to pulverize drops on the bulk cargo dish 6 from the charging aperture 2 on the top chock 1, disperseed the back to fall along mill tube 10 inner rings, when entering the upper strata raceway by abrading-ball 7 roll extrusion, rub with the hands broken and continue to fall to middle level and lower floor's raceway, scrape from the discharging opening 14 on the support 12 through the thickness pruinescence material scraping plate 13 after repeatedly pulverizing.Communicate with discharging opening 14 with the negative pressure inlet pipe of the matching used air-flow powder concentrator of the utility model, the thickness powder is together sucked the disengagement chamber of powder concentrator, fine powder is selected, and meal then falls into loading hopper 3 and repeats above crushing process.
