Crusher, anvil device, anvil piece, mineral production line and material crushing method

Abstract

The invention discloses a crusher, an anvil device, an anvil piece of the anvil device, and a mineral production line, and further discloses a material crushing method. The crusher comprises a crushing and shaping structure with material impacting parts (10) and material liner forming parts (11); and the relative position relationship between each material impacting part (10) and at least one material liner forming part (11) is that a material impacted by the material impacting part (10) can be at least partially turned and impacted to a material liner layer (4) of the corresponding material liner forming part (11), so that sequential impact of the material to the material impacting parts (10) and the material liner layers (4) is realized continuously. Due to the ingenious sequential impact manner, not only is the 'material and anvil mixed beating' crushing mode realized in deed, but also the crushing efficiency is high, the shape of crushed particles is good, and the porosity of the crushed material is significantly higher than that of a material crushed with the conventional crusher.

Description

technical field [0001] The present invention relates to a material processing equipment, in particular to a crusher. Further, the present invention relates to an anvil device for a crusher and anvil parts thereof. Furthermore, the invention relates to a mineral production line comprising a crusher. [0002] Correspondingly, the present invention also relates to a material processing technology, in particular, to a material crushing method. Background technique [0003] Crusher is used for crushing and processing of materials, and it is widely used in fields that require crushing and processing of materials, such as mineral processing and production industries, construction industries, food processing industries, etc. The most widely used crusher is the impact crusher, which mainly crushes materials through mechanical impact and collision. In the process of crushing materials, impact crushers often also have requirements for the shape of the crushed materials (that is, par...

AI Technical Summary

Problems solved by technology

According to the CN95201284.7 description, the annular support step 2a is mainly used to set the liner pillar 3a, and it is not mentioned that the annular support step 2a can form a material lining in the work engineering, but it is precisely because of the annular support step 2a. Existence, which makes it difficult for this crusher to perform crushing work effectively during the working process

As mentioned above, since each counter-attack liner 1a is within the range of the annular support step 2a in the direction of the plan view, the material must be accumulated on the annular support step 2a during the working process of the crusher, thereby forming a material lining, But when figure 1 In the crushing arrangement shown, the material liner layer accumulated on the annular support step 2a will cover the material impact area of ​​the counter-attack liner 1a, which leads to the fact that the main method of material crushing in this crusher is still "material beating material". "The crushing mode, even if the material occasionally rebounds to the exposed impact liner, it cannot play a major role in crushing

figure 1 The more serious defect of the crushing arrangement shown is that, since the material is piled up on the annular support step 2a in large quantities, and the impeller device is constantly throwing out the material, this causes the materials to be jammed with each other and even affects the operation of the impeller device. making it difficult to carry out normal crushing work

Practice has proved that this kind of crusher not only has low crushing efficiency, but also the grain shape of the crushed material particles is worse than the traditional "material beating material" crushing mode

[0010] As another example, the crusher disclosed in the Chinese utility model patent CN2868415Y also claims to adopt the crushing mode of "mixing materials and anvils", but from the analysis of its technical scheme, it mainly alternates along the circumferential direction on the inner surface of the crushing cavity The anvil iron and the material lining are arranged in a perfect manner. During the crushing process of the crusher with this structure, the materials accelerated by the impeller generally only collide with the anvil iron and the material lining layer accumulated on the material lining. In the crusher with this structure, there are actually two crushing modes of "material hitting material" and "material hitting anvil" at the same time, and these two crushing modes are relatively separated from each other. Obviously, the crushing efficiency and The shaping effect of the broken particle type is relatively poor. In order to improve this poor crushing effect, this prior art crusher mainly adopts the adjustment of the ratio of the material lining and the anvil in the crushing chamber, hoping to improve the crushing efficiency. and particle shape effect, but no matter how it is adjusted, practice has proved that its crushing efficiency and particle shape effect are difficult to reach a relatively ideal level
