Abstract

The invention relates to the technical field of crushing machinery, in particular to a four-shaft crusher. The four-shaft crusher comprises a rack, wherein an extrusion crushing mechanism and a grinding mechanism positioned below the extrusion crushing mechanism are mounted on the rack; the grinding mechanism comprises a first grinding rotating shaft and a second grinding rotating shaft arranged in parallel with the first grinding rotating shaft; multiple first grinding cutters are arranged along the length direction of the first grinding rotating shaft at intervals in a staggered manner; multiple second grinding cutters are arranged in the length direction of the second grinding rotating shaft at intervals in a staggered manner; a second grinding cutter is corresponding arranged between two adjacent first grinding cutters; the cutting rotation direction of each first grinding cutter is opposite to the cutting rotation direction of each second grinding cutter. According to the four-shaft crusher disclosed by the invention, four crushing rotating shafts are adopted, materials can be pressed by two upper crushing rotating shafts, the two upper crushing rotating shafts have the material crushing function, and two lower crushing rotating shafts are mainly used for crushing the materials. Due to a screen mechanism, rapid screen replacement mechanisms and screen maintenance guide rails are increased.

Description

Technical field [0001] The invention relates to the technical field of crushing machinery, in particular to a four-shaft crusher. Background technique [0002] The existing crushers generally use single-shaft or double-shaft crushers, which have limited crushing efficiency; at the same time, they all lack the function of pressing the upper part, resulting in unsatisfactory crushing effects. [0003] Therefore, in order to solve the above problems, it is urgent to invent a new crusher. Summary of the invention [0004] The purpose of the present invention is to provide a four-shaft crusher, which not only improves the crushing efficiency, but also achieves a good crushing effect. [0005] The present invention provides the following solutions: [0006] A four-shaft crusher includes a frame on which a crushing mechanism and a crushing mechanism located below the crushing mechanism are installed; the crushing mechanism includes a first crushing shaft and a second crushing shaft. A secon...
