EPS Batch Pre-expander Machine
Features of EPS batch pre-expander Machine:
1. Use PLC programmable controller and touch screen to realize man-machine dialog.
Use charging device of automatic nagative pressure , electric weighing, level switch to realize automatic feeding and gauge.
Use auto-controller of temperature and pressure in the chamber and photoelectric level material to realize the uniform and light density of the beads．
EPS beads is formed in the auto-cycle by shock sieve, crushing and transportation fan.
2. Use imported steam reducing valve and proportional valve (optional) to ensure the stable pressure of the reducing valve outlet, and the temperature tolerances within ±1℃ in the chamber. If the block density is above 30kg/m3, the proportional valve should be installed.
3. Hot air drying system (Patent) in the fluidized beds, temperature up to 75℃, ensure the EPS raw material drier, fast mold,speed up the aging process and shorten the production cycle.
4. Separation of auto-charging device and electric weighing with the machine avoids the inaccuracy and unreliability of electric weighing caused by operation.
5. Four security devices on the machine ensure it operates normally and safely. 6. For production techinic 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.
6.For statistics and account of EPS production per day, week, month or year, the electric weighing can be installed with digital printer optionally.
7. Remote communication system can be optionally used to monitor the machine and remedy its faults. Software system can be upgraded to improve its processing properties.
8. Hot air drying system (Patent) in the foam chamber, temperature up to 75℃, making EPS beads more dry, resulting in the density of foam up to 11kg/m3, making forming quickly, especially cut down the fluidized bed to advance the beads’ transportation, speed up the aging and shorten the production cycle.
9. Use new EPS foam processing technology to improve its production efficiency , ensure EPS beads foam more accurately, lightly, fast and have low fault rate during its secure operation.
