Material with high stickiness creates problems in all aspects of the grinding process, including feeding (, making metering into the mill difficult), grinding (e. g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (, plugging the bag filters). There are two ways to grind sticky materials.
