process
Raw material pretreatment:
Raw desert sand is removed from salt (Cl- content<0.01%) by="" screw="" sand="" washer="">
Water content reduced from 15% to 8% by high frequency dewatering screen
Gradient drying:
Wet sand is fed into the three-cylinder dryer from the feeder
Adopting counter-current + down-flow composite heat exchange process:
First zone (120-180 ℃): rapid evaporation of surface water
Second zone (80-120 ℃): the depth of the removal of water of crystallization
Third zone (50-80 ℃): slow Su homogenization treatment
Precision sorting:
Dried sand enters the shaper to enhance sphericity
Output through sorting system:
20-40 mesh (frac sand)
40-70 mesh (glass raw material)
70-140 mesh (3D printing sand)
Intelligent warehousing:
Finished sand enters the constant humidity silo through pneumatic conveying system.
Robot automatic palletizing, with a daily shipping capacity of 5,000 tons.
