Sludge Rotary Dryer Introduction
Dongding Sludge Rotary Drying System is suitable for drying various kinds of sludge with high viscosity. The sludge with moisture of about 85% can be dehydrated and dried into dry powder with moisture less than 10%. After dried, sludge weight will reduce by approximately 60%; and the volume of sludge will reduce by 4-5 times. Thus, the transportation cost of sludge will reduce significantly. Also, environmental problems associated with sludge will reduce substantially.
And sludge dryer design varies from the unique characteristics of the sludge to be processed. The retention time, length and diameter, air flow configuration (co-current or counter-current flow), are specially designed according to characteristics of the raw material; and when it comes to sticky materials, different types of lifting devices, cleaning devices, and crushing devices inside the dryer can solve the problem of walls sticking during the drying process. And the main body of the drum can be made of carbon steel or stainless steel to meet the special needs.

Application & Materials
The sludge dryer system can be applied to the drying of activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, tanning sludge, electroplating sludge, municipal sludge, biological fermentation sludge, etc. In addition, it is also applied to coal sludge drying, coal slurry drying, etc. The dried product produced out of drying sludge can be used as fertilizer, biofuel, etc.
Sludge Rotary Dryer System
The whole sludge rotary drying system consists of the dehydrator machine (if needed), feeder, sludge rotary drum dryer, discharging machine, induced draft fan, cyclone dust collector and distribution cabinet, etc.
