According to testing, the double-canister dryer has high thermal efficiency which exceeds 50% of traditional single canister dryer with obvious energy-saving effect and coal saving.
For scientific, rational, high efficient and energy-saving dryer, the thermal exchange of material is conducted in the form of thermal current radiation and convection in inner canister while, the thermal exchange is carried out in the form of conduct and convection in outer canister.
The length of this double-canister dryer is much less than before, which is good for technical layout. Its entire length is shorter than 50% of single-canister dryer to retrench the workshop floor area and project investment, which is more suitable for technical transformation in old workshop.
