Plate chain composite crusher with adjustable crushing ratio

Abstract

The invention discloses a plate chain combined type crusher with an adjustable crushing ratio. The plate chain combined type crusher comprises a lower machine body, a movable tooth roller and a chain wheel assembly. The movable tooth roller is arranged on the lower machine body, a chain wheel assembly is arranged on the lower portion of the inner side of the lower machine body and comprises a plate chain, a driving wheel and check blocks, the plate chain is meshed with the driving wheel, the check blocks are distributed on the upper surface of the plate chain, and the movable tooth roller and the check blocks on the plate chain form a crushing combination for extruding and crushing materials. A plurality of movable tooth rollers are arranged, and a crushing cavity is formed between each movable tooth roller and the plate chain. The multifunctional crusher has the advantages of being diversified in function, simple in structure, small in occupied space, high in crushing efficiency, low in cost and the like, meanwhile, the crushing ratio can be changed within a large range, and then the adaptability to various operation scenes is improved.

Description

technical field [0001] The invention relates to a crushing device, belonging to the field of mining machinery, in particular to a plate-chain compound crusher with adjustable crushing ratio. Background technique [0002] At present, the crushing operation of ore aggregate is limited by the transmission ratio of the crusher, and the multi-stage crushing process is mostly used. Before each stage of crushing, a screening machine is used to pre-screen the material, and a screening machine is still required after each stage of crushing. For inspection and screening, the ore aggregates must be transported back and forth through the conveyor. As a result, the crushing process is cumbersome, the structure of the crushing operation line is complex, and the entire operation device is bulky, which in turn causes the crushing operation to occupy a large and open space. In addition, ore aggregates mined in mines and narrow terrain must be transported long-distance to open terrain for cr...

AI Technical Summary

Problems solved by technology

This leads to a cumbersome crushing process, a complex structure of the crushing line, and a large volume of the entire operating device, which in turn requires a large and open space for the crushing operation

In addition, ore aggregates mined in mines and narrow terrain must be transported to open terrain for crushing operations, which brings great inconvenience to production; and long-distance ore aggregate transportation consumes a lot energy and the environment

[0003] In view of the above-mentioned technical pain points, if a crusher with an adjustable crushing ratio and a large adjustable range of the crushing ratio can be invented, the current multi-stage crushing can be replaced by a single-machine crushing, the crushing process and crushing device are simplified, and the solution is determined by the multi-stage crushing process. The crushing process is cumbersome and complicated, the crushing device is bulky and occupies a large area; if a crusher with a compact structure and a conveying function can be invented, it can solve the problem that the ore aggregate must pass through a special conveying device for a long distance before the crushing operation. delivery problem
