Sludge drying is the process of transforming sludge into useful products or green fuel.Removal of water reduces storage volume and transportation costs.Thermal drying is used to achieve up to 80 volume reduction and up to 90 weight reduction.
Spray, rotary flash sludge dryers.A spray dryer employs the use of a highspeed centrifugal bowl to get a good separation between the moisture and the sludge.Centrifugal force serves to atomize the sludge into small tiny particles with wide surface area and then spray on top a drying chamber.Inside this compartment, hot gases will be.
Sludge dryer is also called rotary sludge dryer, which can dry materials with 90 moisture content to finished products at one time.In accordance with the characteristics of easy agglomeration during the sludge drying process, it adopts the combined type selfcleaning device, which greatly expands the application scope of single cylinder dryer.
Drying sludge for optimal recovery.The limits of mechanical sludge drying sometimes create the need for thermal drying by water evaporation.Suez has developed a number of sludge drying processes that allow the sludge to be recovered for a multitude of uses as fertilisers, coproducts for composting or as fuel for incineration plants.
Sludge rotary drum dryer introduction zhengzhou dongding drying equipment co., ltd.Has developed a sludge material drying system, is suitable for large viscosity material drying, can dry moisture of 85 to below 10.
Product introduction zhengzhou taida european ctype rotary wing dryer makes up the technical gap in drying machine which can integrates drying and crushing into a whole.This new type dryer can be used to dry materials with 95 moisture content.It can be also used to dry materials with less moisture content without special feeding condition.
Quality rotary drum dryer manufacturers exporter buy sludge rotary triple drum dryer rotary industrial small size for building materials from china manufacturer.
Watropur sludge dryer uses recycled, warm, dry air to gently dry the cake up to 90 dried solids 10 moisture content.The saturated air which comes off the top of the sludge container is passed over refrigerated coils, where the moisture is removed, and then reheated prior to injection into the container.
