The flow path inside a new hydraulic slide-plate screen changer designed for twinscrew extruders transitions from a figure-8 shaped opening into an oval breaker plate and filter. This is said to give more streamlined flow than the typical transition from a figure-8 adapter to a round breaker plate. The new unit from PSIPolymer Systems Inc., Hickory, N.C., also allows the screws to be extended close to the breaker plate, reducing material inventory and residence time. The screws can be pulled out of the extruder through the screen changer. PSI offers the unit in fi ve sizes for twin-screws from 40 to 135 mm. Tel: (828) 345-6264 . www. psi-polymersystems.com
