Machine-made sand preparation system with screening function

Abstract

The invention discloses a machine-made sand preparation system with a screening function, and relates to the technical field of machine-made sand preparation. The machine-made sand preparation system comprises a material storage box, feeding boxes are arranged at the top ends of the left and right sides of the material storage box, and the bottom side of the material storage box is fixedly connected with the top end of a first crushing box. According to the machine-made sand preparation system with the screening function, through the arrangement of the first crushing box and a second crushing box, large sand raw materials can be crushed in sequence, and the sand raw materials can be crushed into small particles to enter a screening barrel; and then through mutual cooperation of a supporting net plate, a first driving motor, a rotating shaft, a first screening net, a second screening net, a third screening net, a blocking ring, a discharging groove and an annular collecting box, crushed sand can be screened out in sequence, large sand blocks can be screened out and discharged through the annular collecting box to be separated from fine sand, and then the fine sand is screened out and discharged through a screening box, and repeated crushing of the sand is avoided.

Description

technical field [0001] The invention relates to the technical field of machine-made sand preparation, in particular to a machine-made sand preparation system with a screening function. Background technique [0002] Machine-made sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. The requirements for machine-made sand are general construction The requirements for sand use should be strict, and strict screening is required in the production process. [0003] The traditional machine-made sand preparation system in the prior art needs to cyclically crush the sand when processing the sand, so that the sand can be processed into the required size, and if the smaller sand after crushing is not screened in this way, it will The repeated crushing of the sand will increase the ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a machine-made sand preparation system with a screening function, which solves the need to circulate the sand when the traditional machine-made sand preparation system in the prior art processes the sand. In order to process the sand into the required size, if the smaller sand after crushing is not screened, it will cause repeated crushing of the sand, which will increase the operating cost of the sand making machine and reduce the operation of the sand making machine efficiency problem
