How a Friction Screw Washer Cleans Plastic Film

Watch on YouTube (opens a new tab)

This demonstration shows a friction screw washer cleaning flexible film, flakes and regrind. Watch how the material is moved through the washer as the rotor helps scrub dirt and grit from its surface. It’s a closer look at the cleaning work that happens between cutting and the later separation or drying stages.

Where a friction washer fits in a film line

The washer’s angled paddles move shredded material through the machine while the rotor creates friction between the pieces. The scrubbing helps loosen surface contaminants such as sand and soil. The clip demonstrates the same principle for plastic film, flakes and regrind.

To decide where to use a friction washer, identify whether the material mainly carries loose grit or dirt that clings to its surface. Consider what washing or separation happens on either side of the machine. It is one stage in the cleaning process.
