Hollow Blade Dryer is a kind of mixing dryer at low speed by
conducting heating.There is sandwich layer on the tube of the dryer and
hollow blades on the axle in which hot carrier is passing through.Wet materials will make heat exchange with the heating surface of the tube and the blades when it is mixed by the blades so as to reach dry.
结构紧凑，传热面积大，占地面积小干燥时用气量小，粉尘少桨叶相互作用具有自净功能物料停留时间长，填充系数高。
Compact structure,large area of heat conducting,small occu-pied space,less air used when drying and less dust.Blades have selrcleaning function by their interaction and materials have longer dwelling time
This dryer is suitable to dry various kinds of paste,granules and powder materials which have good heat stability,and can dry
heat sensitive materials under special conditions.Solvent can be retrieved during the process of drying and heating medium can be steam.hot water,hot oil etc.Typical materical to be dried are:carbon black.calcium carbonate,plaster,clay,nyloy and polyester slices,polyethylene,polypropylene etc.
