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

Abstract

The invention discloses a high-crushing ratio jaw crusher which comprises a rack, an eccentric drive shaft mechanism, a movable jaw mechanism, a knee plate mechanism and a crushing pair mechanism, wherein the crushing pair mechanism consists of two opposite crushing surfaces, and 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 the 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 jaw crusher with a large crushing ratio. 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:...
