Description

Polystyrene Pre-Expander, EPS Machine, Insulation System Machine Pre-Expander Model : TJF**0, TJF**0, TJF***0, TJF***0, TJF***0. Expanded Density : 6~*0 kg/M3 . Applications : EPS Packing Sandwich Constructions: Light Outer Walls EPS External Wall Insulation Insulated roof Cold Storage Buoyancy Systems EPS and the Environment Recycling EPS Packaging Materials Wood Substitute EPS Batch Pre-expander and Continuous Pre-expander, Fluidized Beds Main features: xxxxx beads enter the fluidized beds (optional) through charging material and expansion , then go into the aging silo through transporting fan to finish their auto �cycle expansion. 2. feeding system includes the first and second feeders. 3. Photoelectric switch controls the level of material in the auto-feeder of negative pressure to realize auto feeding (optional). 4. Foam twice or thrice (optionally) after EPS material�s once pre-expanding. For those factories whose annual output of EPS material below ***0t, only one JF****0C batch pre-expander is necessary to pre-expand heavy & light material simultaneously, which meets the production requirement, improves the production efficiency and saves space & energy. 5.With PLC programmable controller and touch screen to control the whole working procedure automatically&#****7; 6&#****9;Efficient screw conveyor and electronic weighing device attach to the expansion chamber&#****7; 7&#****9;With closed expansion chamber and pressure sensor control technology to realize stable foaming pressure&#****7; 8&#****9;Expansion chamber temperature is controlled by temperature sensor and valve positioner&#****2;ensuring accurate temperature control&#****7; 9&#****9;Vibrating switch control material level to get accurate density&#****2;density tolerance less than±2%&#****7; *0&#****9;Stainless steel Fluidized Bed Drier keeps inside temperature around *0&#***1;.
