SLUDGE DRYER HAVING ENHANCED DURABILITY

摘要

PURPOSE: A sludge drying apparatus is provided to dry sludge with high moisture content such that the moisture content rate of the sludge becomes 10%. CONSTITUTION: A sludge drying apparatus includes a body part, a pair of stirring shafts(160,170), and paddles(162,172). The body part forms a chamber for receiving sludge. The stirring shafts are arranged to the chamber and oppositely rotate in parallel. The paddles are protruded from the stirring shafts and rotate in the sludge. The stirring shafts and the paddles are divided into an introducing section and an exhausting section, and the sections are made of different materials. The exhausting section is made of a Hardox material. The introducing section is made of stainless steel.
