Problems solved by technology

Therefore, the height of the jaw crusher also restricts the improvement of the crushing ratio.
[0008] 2. Constrained by the structure of the jaw crusher
[0009] The lower part of the existing crushing motor jaw has the disadvantage of "force reduction effect", not to mention the crushing mechanism that requires greater crushing force for crushing fine materials

Embodiment 1

[0067] Embodiment 1: as figure 1 As shown, a multi-stage extended crushing cavity is composed of two opposing crushing surfaces, one of which is composed of four jaw plates 1 combined up and down; the four jaw plates 1 forming the crushing surface are separated and spliced ​​to form a ladder Leap structure, the gap between the four jaw plates 1 connected between the two jaw plates 1 is filled by the movable jaw. The tooth structure on the four jaw plates 1 that make up the crushing surface also gradually decreases from top to bottom, that is, the tooth height gradually decreases, the tooth width gradually narrows, and the tooth spacing gradually decreases. .

[0068] The four jaw plates 1 that make up the crushing surface confront the corresponding jaw plates 1 that make up the crushing surface on the opposite side to form a stepped crushing cavity, and the size of the stepped crushing cavity expands step by step from bottom to top.

[0069] In the stepped crushing chamber, ...

Embodiment 2

[0071] Embodiment 2: as figure 2 As shown, the four jaw plates 1 that make up the crushing surface are separated and integrally connected by connecting plates 2 to form a stepped structure.

[0072] The four jaw plates 1 that make up the crushing surface confront the corresponding jaw plates 1 that make up the crushing surface on the opposite side to form a stepped crushing cavity, and the size of the stepped crushing cavity expands step by step from bottom to top.

[0073] In the stepped crushing chamber, the last crushing chamber located at the lower end has a long and narrow structure. The length of the working surfaces of the two jaws forming the long and narrow structure is 550mm, and the angle range between the two working surfaces of the two jaws forming the long and narrow structure is -8 degrees. .

[0074] All the other are with embodiment 1.

Embodiment 3

[0075] Embodiment 3: The working faces of the two jaws 1 forming the long and narrow structure are all flat light plate structures.

[0076] The four jaw plates 1 that make up the crushing surface confront the corresponding jaw plates 1 that make up the crushing surface on the opposite side to form a stepped crushing cavity, and the size of the stepped crushing cavity expands step by step from bottom to top.

[0077] In the stepped crushing cavity, the final crushing cavity at the lower end has a long and narrow structure. The length of the working surfaces of the two jaws forming the long and narrow structure is 300mm, and the angle range between the two working surfaces of the two jaws forming the long and narrow structure is +1 degree. .

[0078] All the other are with embodiment 1.

Abstract

The invention discloses a multi-level expansion type crushing cavity which consists of two opposite crushing surfaces, wherein at least one of the crushing surfaces is formed by combining multiple jaw plates up and down; the jaw plates forming the same crushing surface are separated to form a step jump type structure; the jaw plates forming the same crushing surface are opposite to the jaw plates correspondingly forming the opposite-side crushing surface to form a step type crushing cavity; the size of the step type crushing cavity is expanded and increased step by step from bottom to top. Through a 'sectional expansion' process, the crushing cavity is increased in a step manner (from bottom to top), so that the crushing ratio of a crusher is increased and the crushing property of the crusher is improved, which is the core technology of the invention. By increasing the crushing ratio, the crushing production line also can be changed from a long line into a short line, and the technological progress of the crushing production line is boosted.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a multi-stage expanded crushing chamber. Background technique [0002] Jaw crusher, also known as jaw crusher, is one of the oldest and most widely used crushing equipment. [0003] Among them, the crushing cavity is one of the important structural components in the crusher equipment, and the crushing cavity is composed of two opposing jaw plates. The structure of the crushing cavity of the jaw crusher is a positive V-shaped cavity, and the material enters from the upper port, and moves downward as the particle becomes smaller during the crushing process until it is discharged. [0004] The crushing ratio is an important index to measure the performance of the crusher. The improvement of the crushing ratio of the existing jaw crusher is mainly subject to the following factors: [0005] 1. Restricted by the structure of the crushing cavity [0006] 1. Angle factor: T...
