Abstract

The invention relates to the technical field of building equipment, and provides a machine-made sand fineness modulus control system. The system comprises a feeding system, a sand making machine and a vibrating screen which are arranged in sequence, the vibrating screen comprises a shell and a screen arranged in the shell, the shell is further connected with a vibration excitation motor, a first outlet and a second outlet are formed in the shell, the first outlet is connected with a feeding hole of the sand making machine, and the second outlet is used for outputting finished product machine-made sand, the vibrating screen further comprises an upper cover, the upper cover is arranged in the shell, the vibrating screen comprises a negative pressure dust collector, the negative pressure dust collector is arranged on the upper cover, a negative pressure adjusting unit, a first frequency converter and a negative pressure pump which are sequentially connected are arranged inside the negative pressure dust collector, a first input end of the negative pressure adjusting unit is used for being connected with the controller, the vibrating screen further comprises a negative pressure detection unit, and the negative pressure detection unit is used for detecting the gas pressure in the shell, and an output end of the negative pressure detection unit is connected with a second input end of the negative pressure adjusting unit. According to the technical scheme, the problem that the fineness modulus control precision of machine-made sand is poor in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a fineness modulus control system for machine-made sand. Background technique [0002] Manufactured sand refers to the sand processed by the sand production system. The finished product is more regular, and compared with natural sand, it can better meet daily needs. The existing sand production system generally includes a feeding system, a crusher, Sand making machines and vibrating screens, etc., during use, the stone supplied by the feeding system is crushed by the crusher, and the crushed fine stones are sent to the sand making machine to be further crushed into sand grains, and the sand grains are screened by the vibrating screen to produce two types of stones. One is the stone that has passed through the vibrating screen, and the other is the residual stone of the screen. The former stone is cleaned by the sand washing machine and becomes the finished machine-...
