1. Fluidized bed is attached part of Pre-expander.warm air curtain.produced by high pressure fan and heat exchanger in the fluidized bed.dialyse the expanded EPS beads.
2. Improve the further expansibility,welding and elasticity of the beads in the molding process.
3. Fix in with batch pre-expanders.LH-1200 or LH-1600 have 75 centigrade inside,installed vibratory sieve,shattering blocks and transporting fan.
