Abstract

The utility model relates to a centrifugal bead mill which comprises a rack. An electromotor and a grinding component are fixed on the rack. The grinding component comprises a grinding cavity and a rotating shaft. The electromotor is connected with one end of the rotating shaft, and the other end of the rotating shaft extends into the grinding cavity. Grinding beads are further arranged in the grinding cavity. A centrifugal separator is arranged at the front end of the rotating shaft. A filter is arranged inside the centrifugal separator. The filter is connected with a discharging outlet arranged at the bottom of the grinding cavity. The centrifugal bead mill has the advantages that structure is simple, and the centrifugal separator is arranged at the front end of the rotating shaft, and therefore the grinding beads gather do not around the periphery of a filter net any longer to block the filter net. The centrifugal bead mill prolongs service life of the filter net, reduces maintenance cost and can achieve production in mass flow at the same time.

Description

A kind of centrifugal ball mill

Technical field

The utility model relates to the milling apparatus technical field, especially relates to a kind of centrifugal ball mill.

Background technology

Grinding technique is widely used in industrial circles such as paint, cosmetic material, food, daily use chemicals, dyestuff, printing ink, medicine, agricultural chemicals, magnetic recording material, ferrite, new forms of energy lithium battery; It is the high-efficient grinding dispersing apparatus that its liquid-solid material is carried out wet type stirring, sand milling, dispersion; Ball mill is the bump and the shearing force of ordering about the abrasive media generation high-energy-density of raw material particle and high rigidity with the kinetic energy that the mixer rotation is produced; And with the miniaturization of raw material particle; And see through the separator of gap or mesh structure, and the particulate after grinding is separated with abrasive media, make abrasive media continue in grinding groove, to carry out raw material particle miniaturization processing procedure; Particulate after grinding then centralized collection carrying out the next stage processing procedure, or final finished packing.

Yet existing ball mill volume is less, because in the process of grinding; Polished material and abrasive media are easy to around discharging opening, assemble; Be easy to cause filter screen to stop up or damage, grind the material that comes out and also beat, be difficult to realize jumbo production less than requiring.

Therefore, can realize big capacity, the appearance of the ball mill of big flow is necessary.

The utility model content

The utility model is to provide a kind of centrifugal ball mill for solving the problems of the technologies described above.

The technical problem that the utility model solved adopts following technical scheme to realize:

A kind of centrifugal ball mill comprises frame, on said frame, is fixed with motor and grinding component; Said grinding component comprises grinding chamber and rotating shaft, and an end of rotating shaft links to each other with said motor, and the other end stretches in the said grinding chamber; In said grinding chamber, also be provided with grinding bead, wherein, also be provided with a cyclone at said rotating shaft front end; Inside at said cyclone is provided with filter, and said filter links to each other with the discharging opening of said grinding chamber bottom.

The surface of said cyclone axially is evenly distributed with two above separating tanks, and the inclination angle of said separating tank is between 30 °-90 °.

The surface of said cyclone also evenly is provided with excellent pin-and-hole, is fixed with the rod pin in the said excellent pin-and-hole.

Said filter radially around be equipped with filter screen.

The diameter of said grinding bead is 0.05-0.6mm.

The beneficial effect that the utlity model has is, and is simple in structure, is provided with cyclone through the front end in rotating shaft; Make grinding bead no longer accumulate in the screen pack periphery, stop up filter screen, prolong its service life; Reduce maintenance cost, can realize big flow production simultaneously.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 1-5, a kind of centrifugal ball mill comprises frame 1; On frame 1, be fixed with motor 2 and grinding component 3, grinding component 3 comprises grinding chamber 4 and rotating shaft 5, and an end of rotating shaft 5 links to each other with motor 2; The other end stretches in the grinding chamber 4, in grinding chamber 4, also is provided with grinding bead 8, for realizing fineness of grind; The diameter of grinding bead 8 is 0.05-0.6mm, wherein, also is provided with a cyclone 6 at rotating shaft 5 front ends; Be provided with filter 7 in the inside of cyclone 6, filter 7 links to each other with the discharging opening 9 of grinding chamber 4 bottoms; Filter 7 radially around be equipped with filter screen.

The surface of cyclone 6 axially is evenly distributed with two above separating tanks 10, and the inclination angle of separating tank 10 is between 30 °-90 °.

The surface of cyclone 6 also evenly is provided with excellent pin-and-hole 11, is fixed with rod pin 12 in the excellent pin-and-hole 11.

During work, owing to cyclone 6 is fixed in the rotating shaft 5, along with rotating shaft 5 is rotated; Under rod pin 11 stirred, polished material and grinding bead 8 were collided each other, thereby material is ground refinement; Material is discharged through filter 7 then; When grinding bead 8 is around the filter screen, flow back in the grinding chamber 4 through the separating tank 10 of action of centrifugal force from cyclone 6, can not cause the obstruction of filter 7 like this.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
