Problems solved by technology

[0003] Most of the existing stone crushing devices are discharged after crushing once. The stones obtained by crushing only once are large in size and often need to be crushed repeatedly. This operation is more troublesome, so it is necessary to design a A graded crushing device for crushing

Abstract

The invention discloses a gravel cyclic crushing and screening mechanism, which comprises a first crushing device shell, a second crushing device shell, a first crushing mechanism, a second crushing mechanism and a driving mechanism, wherein the driving mechanism drives a first rotating shaft and a second rotating shaft to rotate. According to the gravel cyclic crushing and screening mechanism, byarranging two crushing mechanisms, stones can be crushed in a graded mode, and the crushing efficiency can be improved; and by arranging a filtering mechanism and a vibrating mechanism, stones whichare not completely crushed can be separated out to be crushed again, and the crushing effect can be further improved.

Description

technical field [0001] The invention relates to a crushing device, in particular to a sandstone circulation crushing and screening mechanism. Background technique [0002] Stone blocks are often used in construction projects, often for paving, etc. In the field of construction engineering, most of the stones used are small in size. Generally speaking, the stones in construction projects are large in size. At this time, a crushing device is needed to crush the large stones into small stones. , in order to meet the demand. [0003] Most of the existing stone crushing devices are discharged after one crushing. The stones obtained by crushing only one time are large in size and often need to be crushed repeatedly. This operation is more troublesome, so it is necessary to design a A graded crushing device is used for crushing. Contents of the invention [0004] The object of the present invention is to provide a sand and gravel circulating crushing and screening mechanism to...
