Abstract

The invention discloses a three-cavity multi-functional jaw crusher with triple-folding symmetric exchange type toothed plates, which is additionally provided with a compaction cavity on the upper end of a crushing cavity of a jaw crusher in the prior art and a subparallel fine crushing cavity on the lower end of the crushing cavity (namely, being in the form of three cavities). The compaction cavity is beneficial for improving the crushing efficiency, and the subparallel fine crushing cavity is beneficial for crushing fines uniformly. The three-cavity multi-functional jaw crusher with the triple-folding symmetric exchange type toothed plates has another technical characteristic that the toothed plates forming the three cavities are symmetrically designed in upper and lower angles and lengths, and cavities at two ends can be exchanged for use. The subparallel fine crushing cavity is a high abrasion region, the compaction cavity is a micro abrasion region, and the two cavities are designed to be exchangeable; and therefore, the two cavities can be complementary to prolong the service life of the toothed plates, and the abrasion production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of jaw crushers, in particular to a three-cavity multifunctional jaw crusher with three-fold symmetrical interchangeable tooth plates. Background technique [0002] Jaw crusher, commonly known as jaw crusher, consists of a movable jaw and a static jaw (also known as a tooth plate jaw) to form a crushing cavity, which simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in medium-sized crushing of various ores and bulk materials in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] There are two major defects in the prior art jaw crusher: [0004] One is that the "V" shaped crushing cavity discharges a pile of triangular-sized materials after each cycle stroke does work. Because the jaw crusher is a typical single-particle crushing (no laminated crushing), the size concentration of the particl...
