Know the Difference Between Impact and Attrition Milling
One of the most commonly used types is called a hammer mill. Lumpy materials are typically fed into the hammer mill, where steel hammers or blades rotating around a central point impact the material flow over and over as agglomerates are broken down into smaller and smaller particle sizes. ... In attrition milling, an abrasive rubbing …
