Principle of operation

Hollw 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 hollow 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.

Features

Compact structure,large area of heat conducting,small occupied space,less air used when drying and less dust.Blades have self-cleaning function by their interacrion and materials have longer dwelling time and high filling coefficient.

Scope of application

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.Silvent can be retrieved during the peocess of drying and heating medium can be steam,hot water,hot oil ect.Typical materials to be dried are:carbon black,calcium carbonate,plaster,clay,nylon and ployester slices,polyethlene,polypropylene ect.
