Product Description

Three drum sand dryer

                        
The three drum sand dryer can be applied in drying raw materials such as yellow sand, slag, clay, quartz sand etc...It's widely used in industries such as dry mortar, cement, building materials, glass, chemicals, and casting etc.
the heat efficiency of three drum sand dryer can be up to 80%. shorter length, it's easy to arrange the work site. gas burner is clean and save space.   




General description:
 The dryer is assembled by three concentric-cylinders which halved joint with different diameters. Computer optimized stock 
guide and lifting blade with different angles and spacing are installed inside the 
cylinder, the structure can ensure that the material being dried runs along the
 direction of screw under the impact of gravitation, stay sufficient time and good 
dispersion in the cylinder to let the material exchange with the heat airflow from
 air heating furnace inside of the cylinder. The special three-cylinder structure 
makes the inner cylinder and middle cylinder being surrounded by the outer 
cylinder to form a self-contained thermal insulation system, the radiated heat 
from surface of inner and middle cylinder assist heat the material in the outer
 cylinder, but the outer cylinder is at the low temperature end, so the heat 
dissipation area and heat loss is reduced significantly.

It has the following character:
1. High heat efficient, can be up to 80%, increase 40% heating efficiency than single drum dryer.
2. Small cover space
3. Can cool the material
4. Can burn gas, oil, coal or biomass fuel
