This flash dryer grinds, dries, conveys and produces heat ...all in one system that handles any material that can be entrained, but won't stick to the duct work during drying.Because it exposes the material to heat for only a few seconds, the Ring Dryer gives you a cooler product with accurate moisture content and no wet spots. And because it recirculates 50% of the heated drying air, you save on fuel costs.
