Continuous Screen Changer with Backflush System ESK B

Description

The continuous double-piston screen changers with a backflush system provide major advantages with their fully automatic cleaning of the screens as soon as a defined maximum pressure is met.

• All thermoplastic materials can be processed
• Optimal design of the melt flow way - short melt residence time
• Low-pressure build-up - to prevent thermal variations of the melt
• No dead spots for fast changes in material or color
• Approximately 75% effective screen area
• Operational reliability and long durability

Function

The piston in the backflush unit redirects the melt flow, so only one piston with screens is currently being used in the production process. The other screen pack is flushed backward, so any contaminants with only minimal melt are removed from the screens through the backflush unit. Afterward, the process is repeated with the other screen pack.

Types

The continuous screen changers with a backfulsh system are available for throughputs up to 3,750 kg/hr.
