The technical process
The water-bearing silica sand is fed into the rotary dryer by a belt conveyor, at the same time, the hot air provided by the heat source enters the dryer. The sand can be fully dried in the dryer. The hot air and water vapor are drawn out of the dryer by the induced draft fan, dust and water vapor are purified by dust removal operation. The dried silica sand is discharged from the outlet through the spiral of the dryer, and enters the finished product warehouse after natural cooling by the belt conveyor.
