Batch pre-expander NKL-PSJ110

(1) This machine uses Mitsubishi PLC and Schneider touch screen, automatic feeding, electronic weighing, temperature control, and material level control to achieve automatic production.

(2) The electronic weighing system and material level control system ensure the density of the foamed material, which makes the bead uniform and maintains the density tolerance within ± 2.5%.

(3) The steam pressure regulating valve controls the temperature and steam pressure of the closed barrel, ensuring constant valve output pressure and controlled internal temperature within ± 1%℃, which keeps the foamed material uniform and prevents granule clumping due to poor temperature control.

(4) Automatic vacuum feeding system, electronic weighing system, combined with level switch to achieve automatic feeding, improved production efficiency.

(5) The closed constant pressure foaming cylinder has high heating efficiency. It can save more than 50% of energy compared with the continuous pre-expander.

(6) This machine uses an automatic discharge system, the high-pressure fan improves the discharge speed.
