Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

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 invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. 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. 1-4, the grinding machine of the present invention comprises a grinding rotor 1, wherein a plurality of grinding blocks 2 are disposed on the grinding rotor 1, and the grinding blocks can be fixed on the grinding rotor 1 by screws.

As shown in fig. 1-2, the grinding rotor 1 is provided with a number of grinding segments 2 in the circumferential direction. The grinding rotor 1 is provided with a plurality of grinding blocks 2 along the axial direction.

As shown in fig. 1 to 4, the grinding block 2 includes a first inclined surface 21 provided on one side of the grinding block 2, and the first inclined surface 21 is inclined outward toward the one side of the grinding block 2. In one embodiment, the intersection 23 of the first inclined surface 21 of the grinding segment with the circumferential surface 11 of the grinding rotor 1 is substantially parallel to the axis of the grinding rotor 1.

As shown in fig. 1-4, the grinding block 2 may further include a second inclined surface 22 provided at the other side of the grinding block 2, the second inclined surface 22 being inclined outward toward the other side of the grinding block 2. The intersection of the second inclined surface 22 of the grinding segment 2 with the circumferential surface 11 on which the grinding rotor 1 is located is substantially parallel to the axis of the grinding rotor 1.

In one embodiment, the grinding block has a trapezoidal cross section.

When the grinding device is used, the grinding rotor 1 drives the grinding block 2 to move at a high speed, and the side surface of the grinding block 2 pushes the grinding balls to rotate and collide. The utility model discloses an area of contact of inclined plane and grinding ball is big, and the grinding ball that promotes is more in quantity, has improved grinding efficiency.

While the foregoing description shows and describes several preferred embodiments of the invention, it is to be understood, as noted above, that the invention 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.
