PLC-controlled pre-expander SPJY700

automaticfor EPP

EPP Pre-expander for 2nd expansion is the special device for Expanded Polypropylene [ EPP is short for Expanded polypropylene, The purpose of EPP pre-expansion is to produce expandable polypropylene particles to the desired density. During pre-expansion, the EPP resins are fed to a vessel containing an agitator and controlled steam and air supplies, this vessel is called EPP Pre-expander. The diameter of the particles increases while the density of the resin decreases. After exiting from the pre-expander, the expanded beads will flow through a dryer to remove moisture, and then go to aging silo. • Chamber diameter: 700mm • Chamber height: 1000mm • Output: 250~300kg/hr • Electronics: Schneider/France • Pressure Reduction Valve: Yoshitake / Japan • Pneumatic: Airtec/China • Butterfly valve: Flowx/Italy • Agitator motor: Guomao/China • Blower: Shengtang/China • CE certificate • Multiple safety features. • Pressure Reduction Valve from Japan is used for steam control • Frequency control of motor speed during expansion • Fluid bed is equipped with heater to shorten aging time • Automatic EPP Silo System is available to work with EPP Pre-expander together. • Body: RAL5012 Blue + RAL3001 Red
