Applications The NEUE
HERBOLD friction washer FW Series is used to intensively
wash plastic materials such as film flakes, granulate to include
PET bottle flake and other types of rigid plastics.
Design The
friction washer is mounted on an inclined frame. The material
enters at the lower end of the friction washer with vertical
in-feed. The special angular flights in conjunction with the high
rpm of the shaft transport the material in an inclined direction
toward the top of the unit and simultaneously executes the washing
phase. Fines, water and soaked fiberous paper are separated
through the perforated screen cage which surrounds the high speed
shaft and allows the separated material to flow down through the
friction washer housing to the lower discharge pipe.
The friction washer is equipped with water injection nozzles which spray
the fresh water or recycled water directly at the screen cage to
assist in screen cage cleaning and prevent clogging.In
conjunction with the water spray the friction washer is
manufactured with a pneumatically operated mechanical screen
cleaner.
