The automatic filter changer for plastic materials to be recycled, post consumer and post industrial, eliminates impurities up to 80 microns and is able to operate up to a temperature of 300 ° C and a pressure of 240 bar without deteriorating the treated material.
Ensures an uninterrupted material flow without significant pressure variations.
The extruder pushes the contaminated plastic material into the filter, where a mechanical filter in steel mesh or micro-perforated sheet (punched or laser-drilled) filters the plastic material.
According to the cleaning mode set, the impurities of the plastic compound that have been blocked by the filter are discharged through the automatic opening of a valve, with minimal waste percentages.
Unlike conventional screen changers, which require the intervention and constant attention of an operator, this continuous automatic screen changer can work automatically and without interruptions.
