1.Description

Rotary drum dryer is the device that is used to heat and dry the materials. Rotary drying machine is generally applicable to granular materials and it can be also used for the drying of some part of sticky pasty materials or the materials with high water content. Rotary dryers are commonly used to dry sand, slag, slime and so on. What is more, the drying machine is one of the drying apparatus typically used in the cement plants, namely, cement rotating dryer.

2.Features

1. High technical content, self insulation cylinder body, 80% thermal efficiency (single- cylinder dryer is only 35%), coal saving is 68% than single-cylinder dryer and output increases 100%
2. The length is good for technical layout, 60% shorter than single-cylinder dryer. Also it’s about 20m³area, reducing plant area and saving 40% investment 
3. Adopt heat resistant and wear resistant steel plate, 4 times wear resistant than the general steel plate, long service time and convenient to maintain. 
4. Outside cylinder body temperature is below 60°(single cylinder temperature is up to 150°), with low outlet temperature. 
5. Low outlet temperature is good for keeping long service life. 
6. Electic consumption reduce 60% 
7. Adopt roller rotation, without large and small gear 

3.Application

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.
