[0076] Further, when the quartz stone is poured into the first crushing box 1 through the feed port 3, the crushing roller 5 in the first crushing box 1 performs the first crushing of the quartz sand. The crushed quartz sand falls on the screening net 9 and is screened by the screening net 9. Larger quartz sand can be retained on the screening net 9. When the quartz sand on the screening net 9 accumulates to a certain extent, the electric telescopic rod 15 is started.
