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.
The friction washers are mounted on an inclined frame. The material enters at the lower end of the 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.
