The BREAK WP automatic screen changer eliminates impurities up to 60 microns and is able to operate up to a temperature of 300 °C and a pressure of 240 bar without degradation of the treated material. It guarantees an uninterrupted material flow without significant pressure variations.
The extruder pushes the contaminated plastic material into the screen changer, where a mechanical filter (punched or laser drilled) takes care to filtrate the plastic material. Depending on the cleaning mode set, the impurities of the plastic compound that have been blocked by the filter are discharged through the automatic opening of the valve, with minimum waste percentages.
Unlike conventional screen changers, which require the constant intervention and attention of an operator, the BREAK WP automatic continuous screen changer can work automatically and without interruptions.
