Embodiment 1

[0042] Such as figure 1 As shown, a machine-made sand production system includes a feed port 1, a conveyor 2 is provided below the feed port 1, a combined crusher 3 is provided under the conveyor 2, and a combined crusher 3 is provided below the combined crusher 3. Back screen 14 and conveyor two 4, combined crusher 3 is made up of coarse crusher 10 and fine crusher 11, wherein, conveyor one 2 sends material in the coarse crusher 10, and the bottom of coarse crusher 10 is provided with Secondary vibrating sorting screen one 12, that is, the discharge port of coarse crusher 10 is provided with secondary vibrating sorting screen one 12, and secondary vibrating sorting screen one 12 sorts the material out of the first grade oversize, second grade There are three kinds of materials, the oversize and the undersize, wherein the oversize of the first level is sent to the coarse crusher 10 for further crushing to form a circuit, and the oversize of the second level is transported to t...

Embodiment 2

[0057] Embodiment 2 is the same as Embodiment 1, the difference is that in order to obtain the target product with a smaller particle size, the material of conveyor 3 8 is transported to secondary sand making machine 19 by elevator 2 18, and the secondary sand making machine There is also a dust collector in the machine 19, and the dust collector is also connected to the stone powder bin. The secondary vibrating sorting screen 420 is arranged below the secondary sand making machine 19, that is, the discharge port of the secondary sand making machine 19 is provided with a secondary vibrating screen. Vibrating sorting sieve 4 20, the bottom of secondary vibrating sorting sieve 20 is provided with fine sand bin 21, wherein, secondary vibrating sorting sieve 4 20 sorts material into primary sieve, secondary sieve and There are three kinds of undersize materials, the first grade oversize is sent to the finished sand bin 9, the second grade oversize is sent to the fine sand bin 21, a...

Abstract

The invention discloses a production method for machine-made sand. The production method comprises the following steps that 1, building stones are conveyed into a feed port (1) and are conveyed into acombined crusher (3) through a conveyor I (2); 2, a coarse crusher body (10) in the combined crusher (3) receives the building stones and coarsely crushing the building stones to be less than 10mm soas to obtain coarse materials; and 3, after the building stones are coarsely crushed by the coarse crusher body (10), the coarse materials fall into a secondary vibration separating screen I (12), the secondary vibration separating screen I (12) separates the coarse material into a first-grade oversize product, a second-grade oversize product and screen underflow according to different grain sizes of the coarse materials, the first-grade oversize product is conveyed into the coarse crusher body (10) by the conveyor I, the second-grade oversize product is conveyed into a fine crusher body (11)through a conveyor IV to be finely crushed, and the screen underflow is conveyed back into a re-separating screen (14) for re-separation. The production method for the machine-made sand has the advantages that the problems that stone powder dust is serious, and the variety is single in the single-batch sand making process can be solved, an existing production method for the machine-made sand canbe improved, and the production capacity of the machine-made sand can better adapt to the modern diversified market demands.

Description

[0001] This application is a divisional application of an invention patent named: A machine-made sand production system and its method, and the application number is: 201610416559.1. The application date of the parent application is June 15, 2016. technical field [0002] The invention relates to a sand making system, in particular to a production method of machine-made sand. Background technique [0003] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. Since a variety of stone materials and various tailings waste resources can be used to process machine-made sand, the sand source is extensive, and the machine-made sand has a complete gradation. The particles are stable and the particle shape is controllable, which can be adjusted according to the demand for sand. Therefore, the replacement of natural sand by machine-made sand is the general trend. The machine-made sand production line is usually composed of a feeder, a crushe...
