Detailed Product Description

PSJ110 Batch pre-expander Main Features:
1) This automatic eps batch pre-expander has a PLC and touch panel with
a fully automatic production cycle controlling filling, electronic
weighing, chamber temperature, pressure and level testing
2) It uses an electronic weighing system and level sensor to control
raw material volumes and expanded density, while ensuring density
tolerances within 3%
3) With advanced proportional and pressure relief valves, chamber
temperature is controlled to within +/-1%
4) In first expansion, density can reach 10 - 45g/L
5) Closed chamber keeps permanent pressure
6) Efficient heating helps save up to 50% steam compare to
continuous pre-expanders
7) With an efficient drying system in the expansion chamber,
material can be dried in the chamber rather than having to use a
fluidized bed
8) Filling is done by a backpressure conveyor, which offers high
efficiency and low labor consumption
9) Compact structure occupies a smaller area
10) Even suitable for using in a plateau area
11) Note: B type machines expand density more evenly than A type, with
smaller areas occupied
