Continuous screen changer ESK B

double-pistonhydraulic pistonautomatic

The continuous double-piston screen changers with 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 of material or color approx. 75 % effective screen area operational reliability and long durability 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 backwards, so any contaminants with only minimal melt are removed from the screens through the backflush unit. Afterwards the process is repeated with the other screen pack. The continuous screen changers with backflush system are available for throughputs up to 3,750 kg/hr.
