What is Sludge Dryer? Sludge drying is a process to dewater and recycle high-moisture sludge as resource. there are mainly two ways to dry sludge, natural drying and mechanical drying. The latter is more efficient. The removal of water reduces the sludge quality and volume, which is to make it convenient to be store and transport the sludge.
• Suitable to dry sludge upto less then 5% without back mixing with sludge moisture upto 90%. • Material of construction of paddle dryer can be carbon steel or stainless steel grade 304L or 316L depending on type of sludge handled. Also special abrasion resistant lining is applied on the paddle surface when handling abrasive sludge.
A sludge dryer is a machine or set of equipment that dewaters sludge by evaporating the harbored water. Technically, sludge drying machines alienate liquid elements from solid waste using distinct dewatering processes. The primary sludge drying processes are thermal and mechanical drying.

Sludge Dryer – De-Watering & Drying 1 kWh electricity alone is capable to remove as much as 4.2 kg of water from wet sludge, comparing to normal 1-2.5 kg water per kWh. Save energy bill and reduce carbon footprint. Reduce wet sludge volume by 67% and weight by 80%. Save transportation cost.
The dryer can recover up to 90% of its heat from the vapor stream in the form of 90°C (194°F) hot water. This waste heat can be useful to heat digesters or be used for other heat requirements like district hot water systems or preheating sludge. This …
The OKADA Sludge Dryer operates by the dehydration principle of circulating dry hot air at 50°C to 60°C through a designated volume of sludge cake. Moisture evaporated from the wet sludge cake will then be channeled to the dehumidifying unit and water moisture condensed via a cooling coil heat exchanger.

Sludge dryer working principle: The sludge dryer is integrated by several drying units, which can greatly improve the processing capacity of each unit, reduce the floor space, and achieve centralized feeding and discharging. Each drying unit consists of a jacketed W-shaped housing and two hollow blade shafts and transmissions.
Drymex ® sludge dryers operate at low temperatures between 20 °C and 50 °C. Lasting Value, Robustness, Reliability What you get is a top quality and reliable system which pays off very quickly because you save so much cost for sludgy disposal. Better Classification and Resource Recovery Once dried, sludge may be eligible for better classification.

LCI's thin film sludge dryers can accept a wide range of sludge types such as digested or undigested sludge, primary and/or secondary sludge, industrial sludge, sludge with high amounts of high strength waste or Biomass, sludge which is poorly dewatered, "sticky" sludges, and more. Safety Safety is paramount when drying sludge.
Drying holds in fully-closed cabinet with low temperature, no exhaust gas or odor is released to the surroundings, thus expensive and complicated odor control devices are avoided. Dried Sludge Storage The dried sludge is 50℃ below. It can be packed directly without further cooling down. Sludge Dryer Thermal Drying Technology
