Objectives At the end of this lesson students should be able to Explain the grinding process Distinguish between crushing and grinding Compare and contrast different type of equipment and their components used for grinding Identify key variables for process control Design features of grinding equipment (SAG, BALL and ROD MILLS) feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and
