Crushing type rotary drum dryer is a kind of newly developed rotary drum dryer based on absorbing international advanced technology and combining features and performance of rotary kiln. It is characterized by high efficiency and small occupation area. Because it is suitable for drying various residues slag, manure and sludge materials, it is also called crushing type rotary drum sludge dryer.

　　TDQ crushing type rotary drum dryer is a drying equipment with high mechanization degree. Flow residence while passing dryer drum is small and energy consumption is low. Aimed at features of sludge, TDQ dryer is set with crushing blades inside which can effectively avoid clustering and guarantee smooth drying process. Sludge after drying can mix with coal for combustion, which realizes aim of the amount reduction, stabilization and harmless disposal.

　　In addition, TDQ dryer can also combine with Taeda® low temperature exhaust gas drying technology which makes use of 150-degree flue gas to dry large amount of sludge in short time. Its system composition: wet sludge automatic dosing conveying----sludge dryer---dust catcher---auxiliary equipment. This system fully takes features of sludge during drying process into consideration and distributes heat source available reasonably and rationally so that to let each set of equipment play its best performance. Make use of existing space to maximally deal with remaining sludge. Meanwhile, this system is also helpful for reducing project investment and fund risk.

● Crushing blades can disperse sludge and evaporation ability is large.
● Equipment occupies less area and running performance is stable.
● Drying period is short. Materials’ drying period always only ranges from 10 to 300 seconds. It is suitable for heat-sensitive materials. If dryer drum is set in vacuum vessel, the system can run at reduce pressure condition.
● It can make use of flue gas and large quantity air volume to dry sludge. Investment and running cost are greatly reduced.
● Fast rotating crushing shaft can crush sludge lump/bulk, which enlarges specific surface area. Moisture can be evaporated fast and stickiness is reduced, which guarantees smooth running of drying procedure.
