Description

Technical Field

[0001] The present application relates to the technical field of grinding machine components, and in particular to a novel in-grinding activation device. Background Art

[0002] Cement mill is the key equipment for crushing materials after they are broken. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries. It can grind various ores and other grindable materials by dry or wet process.

[0003] Although an activated liner has been installed in the third chamber of the cement mill, there is still an ineffective area in the running track of the grinding body in the mill, which restricts the increase in the hourly output of the cement mill and is not conducive to the reduction of power consumption of cement grinding. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a novel in-mill activation device to improve the grinding efficiency of materials.

[0005] The present application provides a novel in-mill activation device, which adopts the following technical solutions:

[0006] A novel in-mill activation device comprises a plurality of activation ring assemblies distributed axially along the inner wall of the mill, wherein the activation ring assemblies comprise a base, a first ring body and a second ring body, wherein the base is fixed on the inner wall of the mill, the first ring body comprises a plurality of first activation liners, and the plurality of first activation liners are distributed on the base in a circular array, the second ring body comprises a plurality of second activation liners, and the plurality of second activation liners are distributed on the base in a circular array, the first activation liners and the second activation liners are arranged in an staggered manner, and a plurality of lifting bars are arranged between two adjacent bases, and the lifting bars are distributed on the inner wall of the mill in a circular array.

[0007] Preferably, the number of the lifting bars is consistent with the number of the first activation liners / the number of the second activation liners, and the lifting bars are arranged in a one-to-one correspondence with the first activation liners / the second activation liners.

[0008] Preferably, one end of the lifting bar away from the inner wall of the mill is a trapezoidal structure.

[0009] Preferably, the lifting bar is screwed onto the inner wall of the mill.

[0010] Preferably, a plurality of the first activation liners and a plurality of the second activation liners are arranged on concentric rings.

[0011] Preferably, both the first activation liner and the second activation liner are provided with cavities.

[0012] Preferably, the activation ring assemblies are provided in four groups.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] The present application sets up multiple groups of activation ring assemblies. During the rotation of the mill, the material and the grinding body will perform parabolic motion in the circumferential direction. The activation ring assemblies can interfere with this relatively stable parabolic motion, making the landing points of the material more dispersed, thereby increasing the probability of crushing the outermost circle material and improving the grinding effect.

[0015] By setting the lifting bar, the vertex of the grinding body's parabola can be changed, the height difference of the grinding body can be increased, the agitation of the grinding body and materials can be strengthened, which is beneficial to reduce the retention area, improve the grinding effect of the grinding body in the third bin, and increase the grinding output of cement mill.

[0016] By arranging the first activation liner and the second activation liner in a staggered manner, the activation ring assembly as a whole is approximately corrugated, which is more conducive to activating the grinding body to run in the mill, eliminating the grinding blind area, and improving the grinding efficiency.
