Continuous Screen Changer ESK

Description

The continuous double-piston screen changer allows screens to be switched out during operation.

• 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 of material and color
• Operational reliability and long durability

Function

Normally, the melt is spread over both pistons, each containing one screen pack. After a defined maximum pressure is met, one piston is moved out hydraulically and the screen pack can be changed. Meanwhile, the complete melt is directed over the second piston. After exchanging the screen pack, the piston is moved back and the production process continues. Afterward, the procedure is repeated with the other piston.

Types

The continuous screen changers are available for throughputs up to 6,000 kg/hr.
