Pulverizer blades grind recyclables such as glass, aluminum, concrete, plastic, coal, and other hard materials into a fine powder. Breaking down such hard substances causes pulverizer discs to dull rapidly. At Accu-Grind, we understand that dull pulverizer blades slow down the recycling process, costing you time and money. Dull blades are also harder on other machine components, reducing longevity. We stock and sharpen OEM pulverizer blades and discs as well as create custom ones to your specifications.
