Raw material crushing device for silicate board production

The utility model relates to the technical field of raw material crushing, in particular to a raw material crushing device for silicate board production. Comprising a crushing bin, a feeding hopper is installed at the top of the crushing bin, a control switch is installed at the front end of the crushing bin, lifting grooves are formed in the inner walls of the two sides of the crushing bin, lifting blocks are slidably connected into the two lifting grooves, and the same screening net is installed at the ends, close to each other, of the two lifting blocks; and elastic springs are mounted at the tops of the two lifting blocks. By arranging a series of structures, a plurality of crushing blades and two scraping plates rotate to crush raw materials in the crushing bin, the crushing efficiency is high, the raw materials adhered to the side wall of the crushing bin are scraped, time and labor are saved in cleaning, the crushed raw materials are screened by moving a screening net up and down, and the crushing effi
