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.
Sludge drying
indirect drying by a thin-film evaporator: the dried sludge is pre-dried to dry content levels of 40% to 50%; mechanical extrusion: the sludge is forced through a perforated grid to form pellets; direct drying by the belt dryer: the final dry content of the pellets is between 65% and 90%
