4.Using the operated reducing valve, the EPS batch pre-expander then can control the temperature of foam tank, ensure the accurate temperature control and lower the water content and so on.
5. Equipped with material positioning controller that can precisely control material density, thus the EPS batch pre-expander can have even material density and remain the error less than ±3%.
6. It also has fluidized bed dryer to conduct automatic screening, material crushing, and to transport the foam material to ripening tank.
7. Its electric elements, valve and so on are all the branded products from both home and abroad.
