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.
With many years of good grinding results, roll grinders [also called roll crushers or roll mills], have been used to reduce the particle size of chemicals, grains, minerals, and other soft to medium-hard materials.They can provide more economical and more effective size reduction than hammer mills, universal mills, or other impact-type mills.
