Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the grinding machine with a centrifugal separator according to the present invention is a vertical grinding machine, and includes a grinding barrel 3, a feeding port 31 is provided on the grinding barrel 3, a grinding chamber is formed in the grinding barrel 3, a first rotating shaft 1 and a second rotating shaft 2 extend into the grinding chamber, which are driven by a first motor 11 and a second motor 21, respectively, a grinding block 12 is provided on the first rotating shaft 1, which drives grinding media to move at a high speed, and the grinding media are extruded and collided with each other to crush the grinding materials, so as to grind particles, and the grinding media are fed through an inlet 4. The first rotating shaft 1 and the second rotating shaft 2 can also be a rotating shaft and driven by a motor.

As shown in fig. 1-3, the centrifugal separator 5 is disposed on the second rotating shaft 2, and includes an upper flange 51, a lower flange 52 and an inner sleeve 54, which are sleeved on the second rotating shaft 2, the upper flange and the lower flange are fixed on the inner sleeve 54 of the separating wheel through screws, a plurality of separating fins 53 are disposed between the upper flange 51 and the lower flange 52, grooves corresponding to the separating fins 53 are respectively disposed on the upper flange 51 and the lower flange 52, the separating fins 53 are embedded in the grooves, and a gap 55 is disposed between the adjacent separating fins 53, and the gap may be larger than the diameter of the grinding medium.

As shown in fig. 1-3, the separating fin 53 has an L-shape (or other shape) in cross-section. At high speed rotation, the strong centrifugal force generated by the large flat surfaces 531 on the L-shaped fins can throw most of the grinding media out of the separator. The utility model can prevent grinding medium from entering the separating wheel by strong centrifugal force, and the gap between the fins is larger than the diameter of the grinding medium, thereby preventing the grinding medium from entering the separating wheel. Simultaneously, facet 532 on the fin also can produce centrifugal force, and the grinding medium that gets into the separating wheel with the minim also gets rid of outside the separating wheel, prevents that the grinding medium from discharging outside the machine through the discharge gate, has strengthened the separation effect.

As shown in fig. 1-3, the second shaft 2 has a discharge passage 22 formed therein, and the material enters the discharge passage 22 after passing through the gap 55.

The centrifugal separator used in the utility model can not be blocked due to continuous high-speed rotation, and has good separation effect.

While the foregoing description shows and describes several preferred embodiments of the utility model, it is to be understood, as noted above, that the utility model is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the utility model as defined by the appended claims.
