High efficient reliable widely used sludge rotary drum dryer with ISO CE approved

Brief introduction of sludge rotary drum dryer :

Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay

stone. Rotary dryer are widely used in building materials, metallurgy, and chemical industry. Rotary dryer is handling by bringing

it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, the dryer slopes slightly so that the

discharge end is lower than the material feed end in order to convey the material through the dryer under.

Advantage of sludge rotary drum dryer :
1. High thermal efficiency(≥ 60%)
2. Medium temperature in outlets(80 degree-120 degree)
3. Alloy steel plate or stainless steel plate(SUS304)
4. Good dry effect (≤ 10% after drying)

Working principle of sludge rotary drum dryer :
The material first go into the inside drum, because there are the spiral shape boards fixed in the drum, when the rotary

drum dryer make rotary working, the spiral shape board will stir the material and make the material do longitudinal

movement, when the material reach the right side of the drum, under gravity effect, the material go into the second drum,

because of director plate device, the material go into the second drum, and the same work principle, the material go into

outside drum, in the drying working process, the material make three times drying, so the material can be dried completely.
