Continuous Melt Filtration

MAS- Upcycling to the next level

MAS Continuous Melt Filtration

Wood, paper, aluminum foil, non-melting polymers etc. are very common impurities in the plastic recycling industry. Conventional filter systems using mesh screens are usually unable to cope with even small amounts of these impurities. The MAS CDF continuous melt filter separates contamination such as paper, wood, aluminum or rubber efficiently and can deal with large amounts of contaminants in the melt stream (up to 5%). A melt pressure-controlled scraper system removes the contamination from the surface of a rotating screen disc into a discharge screw system. The impurities are discharged continuously from the CDF, while the filtered melt continuous to flow downstream to the pelletizing system, profile or sheet die. The melt inside of the filter automatically controls the function of the scraper as well as the speed of the screen and discharge screw(s).

Easy Maintenance – Filter Disc Replacement

Filter discs are manufactured from steel plates that are heat treated for wear resistance. The replacement is very simple as the filter screen is easily accessible once the split housing has been opened. Consequently, the filter screen can be replaced in a few minutes using conventional tools. The screen can be cleaned with a vacuum oven (like the SC 700) and reused numerous times.
