Bio-Organic Materials: Sludge, manure, wood chips, sawdust, bark.
Chemicals & Industrial By-products: Chemical powders, fertilizers, salts, pigments.
Food Processing: Fruits, vegetables, tea leaves, spices.
he working principle of a sludge drum dryer involves indirect or direct heat transfer within a rotating cylinder to evaporate moisture. Here’s a step-by-step breakdown of how it dries the sludge:
Feeding: Wet sludge (with moisture content typically 80% or higher) is fed into the system. A specialized feeder, like a screw conveyor or pump, ensures a consistent and controlled feed rate into the inclined rotating drum.
Lifting and Showering: As the drum rotates, a series of internal fins (lifting flights) pick up the sludge and cascade it down in a “curtain-like” manner throughout the drum’s cross-section.
Heat Transfer & Drying:
Direct Heating: Hot air or combustion gases (from a burner using natural gas, diesel, etc.) flow through the drum, directly contacting the showering sludge. This is the most common method for high-capacity drying.
Indirect Heating: Hot thermal oil or steam circulates in a jacket around the drum, heating the shell, which then transfers heat to the sludge inside. This method is used for more sensitive or potentially explosive sludges.
Moisture Evaporation: The intense heat and the large surface area created by the cascading action cause the water in the sludge to evaporate rapidly.
Transport and Discharge: The combination of gravity (from the drum’s incline) and the flow of hot gases moves the drying sludge toward the discharge end. By the time it exits, the sludge is converted into dry, powdery, or granular pellets with a moisture content as low as 10-20%.
Vapor Treatment: The moist, hot exhaust gases containing water vapor and potential pollutants are sent to an air treatment system, such as a condenser, scrubber, or thermal oxidizer, to clean the emissions before release.
Here is a table outlining the key parameters for our standard rotary drum dryer models. Please note that we specialize in customizing industrial drying equipment to meet your specific capacity and material requirements.
