Feature
This equipment is widely used in research institutes, universities and private companies as research development of ceramics green sheet. And recently, it is also used for coating of paints, chemicals, adhesives, plastics, composite materials, thin films, etc.
Easy to handle and clean. Able to measure from a simple desktop type to experimental equipment of a closed drying zone with a length of several meters.
Roller pressure feeding method of film, unwinding / winding method can be selected and drying hot wind zone can be set for voluntary length as an option.
Principle
The slurry in the dam flows out of the adjustable clearance with the parallel blade and a green sheet is molded on the moving film.

Structure principle chart of DRPTC-150
The slurry in the dam flows out of the adjustable clearance with the parallel blade and a green sheet is molded on the moving film with unwinding mechanism. Fan from blower is filtered by HEPA filter, becomes hot wind with heater and dries green sheet with heating of rubber sheet under conveyor.
