Mining drying equipment three return dryer 3 pass rotary dryer
Three-drum dryer is also called three-cylinder dryer and triple-drum dryer. It has improved internal structure of monocular dryer, which prolongs the time of pre-drying of wet materials and wet materials in the machine, thus improving 50% to 80% of production capacity compared with original monocular dryer.
Drying Materials: Powder, coal, sand, clay, slag, etc.
