UHMWPE Scraper Blade

Xinxing UHMWPE scraper blades are finely crafted and are available in a variety of lengths for efficient drum filter applications. Our UHMWPE scraper blades are laser cut and sharpened to a 23-degree angle. The fine edge of this line of UHMWPE components increases blade life and reduces vibration.

To reduce the number of UHMWPE scraper blades required for a drum filter, Xinxing produces standard 6 inch blades as well as longer lengths including 12 inch, 18 inch, 24 inch, and 48 inch ones. Longer blades and fewer joints extended the blade lives for the filter. Additionally, our longer UHMWPE scraper blades are more easily installed and aligned, which leads to a reduction in filter downtime.

Features of the UHMWPE Machined Parts
1. Highly abrasion resistant
2. Reduce conveyor noise
3. Significantly reduced damage of material
