Whatever your size-reduction challenges, get more for less with screens in Hardox® steel. A good screen will be the main contributor to a consistent particle or fraction size.
Screens made in Hardox® have surprised many end users of gratings with their shape stability for the holes. The secret is consistent hardness through the entire thickness range. Instead of monthly replacements, you could be looking at annual replacements. And excellent bending properties enable a high degree of shape variations.
