Using a roll grinder to achieve narrow particle size distribution

Roll grinders have a long history in reducing many types of bulk materials. This article describes how a roll grinder works and its economic advantages over traditional hammer mills and universal mills. Advantages include narrow particle size distribution, low material heating, and minimal usage of process air.
