EPS polystyrene hot melting machine is a new generation of equipment for producing EPS foam products. The machine adopts new technology with the advantages of high production efficiency, high output, low energy consumption and other features. The EPS foam hot melting machine is mainly composed of the extruder, screw conveyor and supporting parts.
The foam pelleting machine also uses extruding barrel to process the crushed foam pieces.it can melt the pieces into thick liquid things,and then cool it and cut into pellets.
The EPS extruder is made up of barrel, screw, barrel cover and end cap. The barrel is made of special steel tube and equipped with heating jacket to heat uniformly inside the barrel. The screw is located at the bottom of the barrel, which can be rotated by motor through pulley and transmission belt. The screw has two functions: extruding material into a cylindrical shape and conveying material forward during extrusion process by rotating motion. In order to ensure the quality of extruded products and avoid material sticking on screw surface due to temperature difference between material and screw surface, we should use special lubricating oil in production process as well as cooling device such as water cooling or air cooling to keep temperature balance between material and screw surface.
The supporting parts include support plate (to support feeding hopper), feeding hopper (to supply raw materials into feeding pump), feeding pump (to transport raw materials into extruder).
