ProjectChongli 300t/d Crushing Plant in Zhangjiakou, Hebei
Two-stage one closed-circuitcrushing and screening process was adopted.
First, the raw ore was fedinto the ground raw ore bin, and then fed to the jaw crusher by the chutefeeder for coarse crushing. Then, the crushed ore was transported by the 1#belt conveyor to the circular vibrating screen for screening. The products on theupper sieve and the intermediate products of the sieve were combined and fedinto the cone crusher for fine crushing by the 2# belt conveyor. After the finecrushing, the products are combined and fed to the 1# belt conveyor and thenreturned to the sieve for screening. The final product under the sieve wastransported by the 3# belt conveyor to the powder ore bin for storage, forminga second stage and one closed-circuit crushing and screening process. And thefinal crushing size was -20mm.
