Screen changer

The pressure change required to operate a screen changer system with fresh screens can he estimated using a method developed by Carley and Smith [3] and later modified by Todd [4] for a power law fluid. [Pg.481]

The downstream discharge parts correspond exactly to the established components specified for the required throughputs, including throttle start-up valve, screen changer, and underwater pelletizer. [Pg.290]

Screen changer for continuous operation without shut down using standard hinged swing-bolt gate. [Pg.232]

A screen changer is located between the extruder and die to remove any dirt or foreign particles. Gear pumps located between the extruder and die reduce power consumption and provide a more uniform rate of polymer delivery to the die, providing improved gauge control [3]. [Pg.235]

Screen changer A device bolted to the head end of an extruder, between extruder and die adapter, that allows the operator to quickly replace a dirty screen pack with a clean one, usually without having to rethread the downstream line. [Pg.863]

A sliding-plate screen changer (Fig. 5.15a ) has two breaker plates mounted on a support plate a similar screen changer uses cartridge filters in place of the breaker plates. The breaker plates are manually or hydraulically switched when the pressure drop across the breaker plate exceeds a preset value. Then the dirty breaker plate and screens are... [Pg.335]
