ESK SERIE – CONTINUOUS DOUBLE-PISTON SCREEN CHANGER
The continuous double-piston screen changer allows screens to be switched out during operation. The continuous screen changers are available for throughputs up to 6,000 kg/hr.
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. Afterwards the procedure is repeated with the other piston.
