Abstract

The invention discloses a waste secondary screening system in the recycling process of gypsum board waste, which includes a rotary screen, a gypsum paper scrap separation box and a crusher. The outlet, and the gypsum block outlet connected with the feed port of the crusher, the coarse material chute of the rotary screen and the feed port are connected by an inclined conveyor, the discharge port of the crusher is connected with a gypsum powder collection box, and the paper scrap outlet is connected with a Gypsum paper dust collection box and gypsum paper dust separation box are installed with gypsum paper dust separation mechanism, and the gypsum block is crushed into gypsum powder, so that the reused waste can be fully utilized, and the automation of the recycling process of gypsum board waste is realized, which improves the The recycling efficiency of gypsum board waste saves human resources.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of gypsum board waste recycling, in particular to a waste secondary screening system in the process of recycling gypsum board waste. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, and good sound insulation, heat insulation and fire resistance. One of the new lightweight panels. [0003] In the production process of gypsum board, a certain amount of unqualified products will be produced. These unqualified products are often broken or rolled into gypsum blocks and paper scraps, and then added to the rotary kiln together with the desulfurized gypsum for calcination, so as to achieve the purpose of recycling. [0004] However, because the rotary kiln itself does not have the ability to pulverize, some large gypsum blocks and pap...
