    9. Pos. 9: Erema laser filter - used
      1. Model: LF_2_354.
      2. Continuous high-performance filtration system for the separation of "soft" contaminants such as paper, wood, aluminium, copper, foreign polymers, etc. from contaminated plastic melt.
      3. The new scraper star is a considerable boost to efficiency; thanks to its innovative scraper geometry and the new directly connected discharge channels any contaminants are lifted from the screen immediately and forwarded to the coaxial discharge screw.
      4. The contaminants are removed under control and with a minimum of melt via this likewise optimised discharge system.
      5. The scraper and discharge screw speeds depend on the pressure and are controlled fully automatically ("constant pressure operation").

        1. Model: HG_244D.
        2. Hot die face cutter with direct drive technology.
        3. The even melt flow through circular arranged melt channels allows cutting to a steady and uniform pellet shape.
        4. The melt which comes out from the heated die face is cut off by rotating knives and centrifugal forces push the pellets produced outward in a rotating water ring.
        5. This water ring flows through the stainless steel housing without direct contact to the die and ensures a perfect pellet cooling and transporting.
        6. Drive: patented floating AC direct drive with lifetime lubrication.
