AI Technical Summary
The traditionally designed activation ring gives the small-sized grinding body a relatively small activation space, which makes it difficult to effectively activate the grinding energy of some small-sized grinding bodies, and the grinding ability is reduced. At the same time, the grinding length and diameter ratio of the grinding machine is too small, resulting in insufficient grinding of the material and low grinding efficiency.
A rumination-type grinding system device is designed, including a first activation ring and a second activation ring alternately arranged in the mill barrel. The inner diameter of the first activation ring is greater than the inner diameter of the second activation ring, forming a highly dislocation structure to activate the grinding ability of the small-sized grinding body and increase the grinding time of the material through the rumination effect of the second activation ring.
Effectively activate the grinding ability of small-sized grinding bodies, improve grinding efficiency, and increase the grinding time of the material through the rumination effect, and improve the grinding fineness of the material.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building material production equipment, in particular to a ruminant grinding system device suitable for superfine grinding. Background Art
[0002] With the development of the building materials industry, the demand for ultrafine materials is increasing. By transforming ordinary ball mills into ultrafine mills, ultrafine grinding of materials can be achieved. An activation ring is set in the cylinder of the ball mill, which can effectively separate the grinding body and prevent the material from flowing too fast, thereby improving the grinding efficiency and increasing the output of the mill.
[0003] However, as the building materials industry continues to improve the utilization rate of solid waste resources, the requirements for the fineness of solid waste materials are getting higher and higher, and the required grinding body diameter is getting smaller and smaller. The activation ring of the traditional design gives a relatively small activation space to the small-sized grinding body, and the grinding energy of some small-sized grinding bodies is difficult to be effectively activated, resulting in a decrease in the grinding capacity of the grinding body. At the same time, because the aspect ratio of some mills is too small, the material stays in the mill for a short time, and the material is not fully ground, resulting in low grinding efficiency of the ultrafine mill. Utility Model Content
[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a ruminant grinding system device suitable for ultrafine grinding.
[0005] The utility model proposes a ruminant grinding system device suitable for ultrafine grinding, comprising: a mill cylinder and an activation ring arranged in the mill cylinder, wherein:
[0006] One end of the mill cylinder is the feed port, and the other end is the discharge port;
[0007] The activation rings include a plurality of first activation rings and a plurality of second activation rings, and the inner diameter of the first activation ring is greater than the inner diameter of the second activation ring. From the feed port of the mill cylinder to its discharge port, all the first activation rings and the second activation rings are alternately arranged along the axial direction of the mill cylinder, and a spacing is reserved between each adjacent first activation ring and second activation ring.
[0008] Preferably, a feed hole is provided on the first activation ring.
[0009] Preferably, the second activation ring is the last one in the direction from the feed inlet of the mill cylinder to the discharge outlet thereof.
[0010] Preferably, the inner diameter of the second activation ring is larger than the diameter of the feed port.
[0011] Preferably, the inner diameter of the second activation ring is larger than the diameter of the discharge port.
[0012] The activation rings in the utility model include a first activation ring and a second activation ring, and the two are alternately arranged in the mill cylinder, and the inner diameter of the first activation ring is larger than the inner diameter of the second activation ring, so that a sufficient grinding space is formed between two adjacent first activation rings, and after the material enters the space, the first activation ring in the space stirs the material and the grinding body to activate the grinding capacity of the small-sized grinding body. While the material moves forward, some large-particle coarse materials in the material cannot pass through the second activation ring due to their large mass and are returned for re-grinding, thereby forming a rumination effect of the material, increasing the grinding time of the material and improving the grinding fineness of the material. Compared with the prior art, it has the following advantages:
[0013] (1) The first activation ring can effectively stir the material and the grinding body, increase the activation area, activate the grinding ability of the small-sized grinding body, and improve the grinding efficiency.
[0014] (2) The second activation ring causes part of the large particles to be returned for re-grinding during the forward movement of the material, thereby forming a rumination effect of the material, causing the large particles to be re-grinded, thereby increasing the grinding time of the material.

[0020] Reference Figure 1-4 The utility model proposes a ruminant grinding system device suitable for ultrafine grinding, comprising: a mill cylinder 1 and an activation ring arranged in the mill cylinder 1, wherein:
[0021] One end of the mill cylinder 1 is a feed port, and the other end is a discharge port. The activation rings include a plurality of first activation rings 2 and a plurality of second activation rings 3, and the inner diameter of the first activation ring 2 is larger than the inner diameter of the second activation ring 3. From the feed port of the mill cylinder 1 to the discharge port, all the first activation rings 2 and the second activation rings 3 are alternately arranged along the axial direction of the mill cylinder 1, so that in the axial direction of the mill cylinder 1, the inner ring surface of the first activation ring 2 and the inner ring surface of the second activation ring 3 form a highly dislocated structure in the radial direction. A spacing is reserved between each adjacent first activation ring 2 and second activation ring 3 to form a sufficient grinding space between two adjacent second activation rings 3.
[0022] Reference Figure 5 The material enters from the feed port of the mill cylinder 1. During grinding, under the action of the first activation ring 2, the material and the grinding body in the cylinder are fully stirred to activate the grinding ability of the grinding body on the material, so as to improve the grinding efficiency. Some fine materials in the material pass through the second activation ring 3 under the push of wind and move toward the discharge port of the mill cylinder 1, while some coarse materials in the material cannot pass through the second activation ring 3 and are blocked by the second activation ring 3 and re-ground, thereby forming a rumination effect of the material, increasing the grinding time of the material and improving the grinding fineness of the material.
[0023] In a further embodiment, a material passing hole 21 is provided on the first activation ring 2 , so that part of the material can pass through the first activation ring 2 through the material passing hole 21 , thereby further increasing the stirring effect of the first activation ring 2 on the material.
[0024] In a further embodiment, the second activation ring 3 is arranged at the end in the direction from the feed port of the mill cylinder 1 to its discharge port to prevent the discharge of unqualified coarse materials and ensure that the fineness of the discharged materials meets the requirements.
[0025] In a further embodiment, the inner diameter of the second activation ring 3 is larger than the diameters of the feed port and the discharge port, respectively.
[0026] In addition, the first activation ring 2 and the second activation ring 3 in this embodiment are both welded and fixed to the mill cylinder 1 .
[0027] As can be seen from the above, the activation rings in the utility model include a first activation ring 2 and a second activation ring 3, and the two are alternately arranged in the mill cylinder 1, and the inner diameter of the first activation ring 2 is larger than the inner diameter of the second activation ring 3, so that a sufficient grinding space is formed between two adjacent second activation rings 3, and after the material enters the space, the first activation ring 2 in the space stirs the material and the grinding body to activate the grinding capacity of the small-sized grinding body. While the material moves forward, some large-particle materials are unable to cross the second activation ring 3 due to their large mass and are returned for re-grinding, thereby forming a rumination effect of the material, increasing the grinding time of the material, and improving the grinding fineness of the material. Compared with the prior art, it has the following advantages:
[0028] (1) The first activation ring 2 can effectively stir the material and the grinding body, increase the activation area, activate the grinding ability of the small-sized grinding body, and improve the grinding efficiency.
[0029] (2) The second activation ring 3 causes part of the large-particle material to be returned for re-grinding during the forward movement of the material, thereby forming a rumination effect of the material, causing the large-particle material to be re-grinded, thereby increasing the grinding time of the material.
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
