Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a new type of tuff stone crushing device. Background Art

[0002] Tuff is a volcaniclastic rock. More than 50% of the volcaniclastic materials in its composition have a particle diameter of less than 2mm. It is mainly composed of volcanic ash and has a loose or dense appearance. The stratified ones are called layered tuffs. The colors are various, including purple, grayish white, grayish green, etc. According to the volcaniclastic components it contains, it can be divided into: crystalline tuff, glassy tuff, and rock tuff. Tuff is a commonly used building material, and can also be used as a raw material for making cement and extracting potash fertilizer. Before tuff stone is needed as a building material, it must first be crushed.

[0003] For example, a Chinese utility model patent (CN210187369U) discloses a ore crusher, which states: "By replacing the traditional flat roller surface structure with a sharp gear ring, the extrusion force on the ore when the gear ring rotates is more concentrated, which can quickly crush hard ore and improve ore crushing efficiency. It has stronger protection against the crushing impeller, and the gravity of the ore when it falls is converted into impact force on the ore itself, making the ore easier to decompose and more efficient in cracking. Four sets of extrusion and crushing devices are used for extrusion operation, and the opposite extrusion plates extend forward synchronously, and the adjacent extrusion plates extend forward alternately. Conical crushing teeth are provided on both sides of the extrusion plates to ensure that the working range of the conical crushing teeth can effectively cover the entire inner cavity of the main machine." It also points out: "The existing ore crusher design is relatively traditional, and most of them use a rotatable breaker to crush the ore, and its crushing capacity is limited. As a result, the existing ore crusher is not efficient in crushing solid ore, and it is difficult to crush hard ore quickly." Technical deficiencies.

[0004] Based on the above, it can be seen that the following technical problems exist in the prior art: in construction projects, tuff stone, as a commonly used building material, first needs to be crushed. Because the tuff stone itself has a high hardness, and some current crushing equipment has a single method for crushing tuff stone, resulting in problems such as low crushing efficiency. For this reason, the present application proposes a new tuff stone crushing device. Utility Model Content

[0005] Based on this, it is necessary to provide a new type of tuff stone crushing device to address the above-mentioned technical problems. Through the overall structural coordination design, when crushing tuff stone with higher hardness, the tuff stone can be firstly quickly impacted by the punching and chiseling assembly to make the tuff stone quickly break, and then the split tuff stone is crushed and crushed by the first rolling roller and the second rolling roller, thereby abandoning the single crushing method of traditional crushing equipment and effectively improving the crushing efficiency of tuff stone and other building materials.
