1plished by loading the EPS beads into the feeder, expansion of the EPS beads, the expanded EPS beads will then enter the fluidized bed optional , and then go through the Centrifugal Fan and Conveying device to be transported into the Aging Silos. 2. The machine’s feeder system includes the first phase and second phase feeders. The first phase feeder uses the transformer to regulate the feeding speed, the second phase feeder uses the method of movement rail and wind pipe to blow the EPS Beads to cool down the temperature, ensuring that feeding is stable. 3plish the automatic feeding, the Photoelectric Switch should control the level of the EPS beads in the Automatic Negative Pressure Feeder Optional .
