Using a closed-loop fine-classifying/fine-pulverizing system to improve fine powder processing

This article discusses a closed-loop fine-classifying/fine-pulverizing system that can improve fine powder processing by improving classifying and size-reduction efficiency. Sections describe the closed-loop system's components and operation, as well as tests showing how the system was used to improve the product yield of photocopy toner in a typical toner production process.

If you produce fine powders, you know they're used primarily as raw materials or intermediate products rather than finished products and that processing can improve the powder's properties for these uses. While processing often concentrates on improving the powder's chemical properties, improving the physical properties is usually just as important.
