Detailed Product Description

Batch Pre-expander ( EPS machinery , Plastic machinery )

Features:
1) Uses PLC programmable controller and touch screen to realize man-machine dialog
2) Uses charging device of automatic negative pressure, electric weighing, and level
switch to realize automatic feeding and gauge
3) Uses auto-controller of temperature and pressure in the chamber and photoelectric
level material to realize the uniform and light density of the beads
4) EPS beads is formed in the auto-cycle by shock sieve, crushing and transportation
fan
5) Uses imported steam reducing valve and proportional valve (optional) to ensure
the stable pressure of the reducing valve outlet, and the temperature tolerances
within ±1°C in the chamber. If the block density is above
30kg/m³, the proportional valve should be installed
6) Hot air drying system (patented) in the fluidized beds with temperature up to
75°C ensures the EPS raw material drying and fast molding, speeds up the
aging process and shortens the production cycle
7) Separation of auto-charging device and electric weighing with the machine avoids
the inaccuracy and unreliability of electric weighing caused by operation
8) Four security devices on the machine ensure that it operates normally and safely
9) For production technical memory and quantity statistic, operator can find the foam
parameter of manufacturer's used EPS raw material and simultaneously set the
different foam parameter by themselves
10) For statistics and account of EPS production per day, week, month or year, the
electric weighing can be installed with digital printer optionally
11) Remote communication system can be optionally used to monitor the machine
and remedy its faults
12) Software system can be upgraded to improve its processing properties
13) Hot air drying system (patented) in the foam chamber with temperature up to
75°, makes EPS beads drier, resulting in the density of foam up to
11kg/m³, making forming quickly, especially cut down the fluidized bed to
facilitate the beads' transportation, speed up the aging and shorten the production
cycle
14 Uses new EPS foam processing technology to improve its production efficiency,
which ensures that EPS beads foam more accurately, lightly, fast and have low
fault rate during its secure operation
