Back to Basics Hammer Milling and Jet Milling

2017-10-23  A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding

P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process

Hammer Milling and Jet Milling Fundamentals AIChE

2021-6-2  Material with high stickiness creates problems in all aspects of the grinding process, including feeding (e.g., 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 (e.g., plugging the bag filters). There are two ways to grind sticky materials.
