Introduction

EPS continuous pre expander machine is functioned to expand EPS raw material to required density, machine works in continuous way both in taking raw material and discharging expanded material.The machine can do second and third expansion to get low density.

EPS continuous pre expander machine is a kind of EPS Machine working with mechanical control. EPS raw material is first filled from screw conveyor to expansion loader. At the bottom of loader is the screw, to move material from loader to expansion chamber. During steaming, agitating shaft is moving constantly to make the material density even and uniform. Raw material move to chamber continuously, and after steaming, material level continuously move up, till the material level comes to same level of discharging opening port, then material will automatically flow out. The higher the discharge opening is, the longer the material stays in the barrel, so the lower the density is; the lower the discharge opening is, the shorter the material stays in the barrel, so the higher the density is. The control of the continuous pre-expanding machine is very simple. Whether the steam pressure is stable or not has a great influence on the density of expanding. Therefore, our continuous pre-expanding machine is equipped with a Japanese pressure reducing valve. In order to make the steam pressure in the machine more stable, we use the screw to feed the material at a uniform speed, and the uniform steam and uniform feed are as uniform as possible.
