2): the work in-process in raw material cabin by the first belt conveyance to the material screen that shakes;
3): be provided with three kinds of sieve apertures in the material screen that shakes, described sieve aperture is respectively the first sieve aperture, the second sieve aperture and the 3rd sieve aperture, and the aperture of the first sieve aperture is 50mm, and the aperture of the second sieve aperture is 20mm, and the aperture of the 3rd sieve aperture is 5mm; Work in-process are divided into two-way, a through the material screen vibratory screening that shakes: particle diameter is that the following work in-process of 5mm advanced the 3rd a sieve aperture screening part and enter product conveying belt, and a part enters the feed back conveying belt; B: the work in-process that particle diameter is greater than 5mm enter the feed back conveying belt;
4): the work in-process transportation that enters the feed back conveying belt is sent to the adjusting feed bin;
5): enter the work in-process of regulating in feed bin and be divided into two-way, a: a part of work in-process enter secondary and regulate conveying belt; B: another part work in-process enter feed back transhipment conveying belt;
6): the work in-process that enter secondary adjusting conveying belt reenter the material screen that shakes and are screened;
7): enter the defeated work in-process that turn conveyor belt of feed back and be transported in crusher and carry out fragmentation;
8): the work in-process after crusher in crushing pass through the batch mixing tape transport in the first conveying belt;
9): the first conveying belt again is transported to by the work in-process in raw material cabin and the work in-process after crusher in crushing the material screen that shakes and is screened;
10): so far, repeating step 2), 3), 4), 5), 6), 7), 8), 9) circulation of sieved → broken → screening again is until half-finished particle diameter completely is less than 5mm, the finished product that is less than the 5mm particle diameter is transported to finished bin by product conveying belt
Further, described adjusting feed bin can be controlled the half-finished amount entered in secondary adjusting conveying belt.
Beneficial effect of the present invention: than prior art, use this screening → fragmentation → circulation of screening again, can be controlled the particle diameter of melting waste slag sand, be less than 5mm particle diameter and the half-finished batch mixing screening, adjusting, the pulverizing that are greater than the 5mm particle diameter, can effectively improve the quality of products, and can reduce energy consumption.
