Embodiment 1

[0119] Embodiment 1: as figure 1 , image 3 , Figure 4 , Figure 5 with Image 6 As shown in the figure, a jaw plate with ultra-fine crushing function of the jaw crushing chamber includes two jaw plates 1 facing each other to form at least two stepped structure crushing chambers, and tooth-shaped structures 2 are arranged on the working surfaces of the two jaw plates; the stepped structure crushing chamber 3 The angle formed by the confrontation between the two jaw plates of the working face gradually decreases from top to bottom, forming an angle ladder structure; the tooth structure 2 on the two jaw plate working faces of the stepped structure crushing chamber 3 also moves from top to bottom according to the The stages gradually become smaller, that is, the tooth height gradually becomes lower, the tooth width gradually narrows, and the tooth spacing gradually becomes smaller, showing a tooth-shaped ladder structure.

[0120] In the stepped crushing chamber 3, the worki...

Embodiment 2

[0123] Embodiment 2: as figure 2 As shown, in the stepped crushing chamber 3, the working faces of the two jaw plates 1 located at the bottom of the final stage of the crushing chamber are narrow and long, and the angle range formed by the confrontation between the two jaw plates 1 working faces is +3 degrees; forming a long and narrow structure The length of the working surfaces of the two jaw plates is 550mm, and one of the working surfaces of the two jaw plates 1 forming a long and narrow structure is a flat light plate structure.

[0124] The stepped crushing chamber 3 has a four-level stepped structure. The two jaws of the stepped crushing chamber 3 are spliced ​​separately.

[0125] In the stepped crushing chamber, the shape of each stage of the crushing chamber is a trapezoidal structure with a left-right asymmetrical top and a bottom.

[0126] All the other are with embodiment 1.

Embodiment 3

[0127] Example 3: In the stepped crushing chamber 3, the working faces of the two jaws 1 located at the bottom and the last stage of the crushing chamber are narrow and long, and the length of the two jaws forming the long and narrow structure is 300mm.

[0128] All the other are with embodiment 1.

[0129] A method for realizing a crushing pair with an ultra-fine crushing function is characterized in that it includes the following content:

[0130] 1. The structural design of the long and narrow crushing cavity (located at the bottom of the crushing cavity of the whole crusher);

[0131] The jaw crusher is characterized by periodic cycle work, that is, it takes each revolution of the eccentric shaft as a cycle. Since the feeding speed of the jaw crusher is the free fall speed, as long as the speed of each crusher is determined, the material drop (that is, the distance the material is pushed) in each cycle of the crusher is a definite value. At this time, the cavity width of...

Abstract

The invention discloses a crushing pair with a superfine crushing function and an implementation method of a superfine crushing function thereof. The crushing pair comprises two jaw plates which are oppositely arranged to form an at least two-level step structure type crushing cavity, wherein the step structure type crushing cavity formed by the opposite working surfaces of the two jaw plates is gradually reduced step by step from top to bottom and forms an angle-step type structure, and the working surfaces of the two jaw plates of the final-level crushing cavity at the lower end in the step structure type crushing cavity are of a long and narrow structure. The remarkable functional characteristic of the crushing pair disclosed by the invention is to realize a supernormal and superfine crushing function. By improving the matched crusher structure, single-machine direct crushing for sand production and even crushing for powder production can be realized.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, more specifically to a crushing pair with ultra-fine crushing function and a method for realizing the ultra-fine crushing function. Background technique [0002] Jaw crusher, also known as jaw crusher, is one of the oldest and most widely used crushing equipment. [0003] Jaw crusher is a typical "coarse crushing" equipment. [0004] There are two meanings here: [0005] 1. The jaw crusher is not a precise device, that is to say, it has a simple structure, is easy to manufacture (ordinary machine tools can do it), is convenient to use and maintain, and the operating cost of the jaw crusher is also very low (for example, the wear of the jaw crusher is the same as that of the impact crusher. 1 / 3-1 / 5 of that of impact crushers, power consumption is 1 / 3-1 / 2 of impact crushers), so jaw crushers have been popular so far; [0006] 2. The material produced by the jaw crusher is very thick (...
