Working principle
The drum forming machine is a cooling crystallization process where the molten material in the material tray comes into contact with the cooled drum, forming a material film on the surface of the drum. Through the heat exchange between the material film and the strand wall, the material film is cooled and crystallized, and the crystallized material film is scraped off by a scraper to form a sheet like product.
Rotary drum drying is a continuous process of heating and drying materials or strip materials attached to the outer wall of the drum through a rotating drum and heat transfer.
