Process flow The mined ore raw material is coarsely crushed and then passed through a feeder into a jaw crusher for initial breaking and screening. Then through the conveyor into the medium and fine crusher cone crusher, At the same time, the screening system separates 5~30mm materials, stores them in the buffer tank at the top of the sand making machine, and breaks into 4 vertical shaft crushers through the feeder. It is then conveyed by a belt conveyor to the finished screening shop for screening. The separated >20mm material is returned to the sand making machine through the belt conveyor for crushing; The separated 10~20mm material is stored as a finished product in the finished product stacker; The separated 0~5mm material is washed into the water washing system through the chute. Feeding machine Jaw crusher Single cylinder cone crusher Multi cyli nder cone crusher Finished sand Sand washing Machine Sand making machine vibrating screen Water treatment system Finished aggregate Crushing system The crushing system in the whole production line is divided into three parts: first breaking, medium fine crushing and sand breaking. First break: 140mm < preliminary breaking material fineness ^ 800mm Medium and fine crushing: 30mm Sand crushing: 0~5mm Screening system

After each part is broken, it will enter the corresponding material fineness screening system for fineness screening, which part of the material will be entered into which part of the crushing system. Washing system The 0~5mm materials separated by the screening system are firstly washed into their respective sand washing systems for further cleaning. The separated sand enters the dewatering screen for dehydration and finally enters the finished sand pile shed for storage. Wastewater utilization system After the mud-containing wastewater is dehydrated by the cyclone and the dewatering sieve,...
