● DWD Seroes Belt Type Droer
|
 Descriptions:
DWD series belt drier is a new elt drier,its' techinlolgh is more advanced,The machine has widly used feils,becauws of more reasonalbe astrruction,hiht heating effacet,steady operation,it is widly used in drying for chemical idustry,organic pigment,dystuff, slag of blast furnace,feed,food and so on.
|
Working principle:
Raw material to be dried will be spread onto the screen belt through suitable feeding mechanism,When drying,hot air will be forced to input to raw material from up and Iow screen belt,It makes the surface of every particulate become surface to be heated.The area to contact with hot air is increased and the heat conduct area is increased remarkably.The diffused distance of moisture in raw material is shortened.Gherefore the dffective drying operation can be carried out. Particularly it is suitable for drying raw material that has been pre-formed(The factory can supply series pre-forming equipment, refer to post page).ln a word , if choose the series drier,it has hith stability and energy saving. |
Features:
The mount of air,temperature of heat,stay time od raw material can be adjusted in order to get the best effect.
The moistrue of finished product can be adjusted.
The raw material is relative static in belt,and so the size and dust will be kiiped.
The belt' s type will be shoose,such as matral mesh or wiberated plate.
The belt can be clean,because of the heating room is seperated from drying room.
According to requirst,the Iow plate can be equipped cleaning equipment to remove a little rof aw materials to outlet.
According the moisture of rqw material,customer can choose multi-set to establish. |
Application:
It is suitable in drying for pre-shapping paste raw materials,such as pigment,dystuff and so on.
It is suitable in drying for high naumber ator polymen,ferric oxide, fluor,medicine,flavoring,glue,and other chemical porducts, fetilizer,feed and so on. |
