Expanded polystyrene pre-expander SPJ130A

PLC-controlledautomaticdiscontinuous

1.With PLC programmable controller and touch screen to control the whole working procedure automatically . 2.Efficient screw conveyor and electronic weighing device attach to the expansion chamber. 3.With closed expansion chamber and pressure sensor control technology to realize stable foaming pressure. 4.Expansion chamber temperature is controlled by temperature sensor and valve positioner, ensuring accurate temperature control. 5.Vibrating switch control material level to get accurate density,density tolerance less than±2%. 6.Stainless steel Fluidized Bed Drier keep sinside temperature around 70. Note: 1. Intelligent density control system enables machine to get timely density repore and to automatically adjust parameters according to density tolerance(optional). 2. Secondary expansion device for SPJ130、SPJ160 is optional.
