When the pre-fired beads are discharged, the temperature change inside the barrel is very small, and the occurrence of condensed water and the agglomeration of the pre-fired beads can be eliminated, so the moisture content of the raw materials can be reduced and thermal energy can be saved. + This intermittent pre-expander adopts automatic program control in operation from feeding, heating, discharging, feeding to air-drying, and the adjustment is convenient and accurate. The pre-fired beads rise from the bottom to the top. When they reach a certain height, they can be discharged by a signal from the photocell. The action is accurate and sensitive. When the foaming pressure is stable, the density is almost the same. The correct choice for the molding conditions is important.
