Nano Grinding MillsMethods — When Smallest is Best

网页Fortunately, industry demand for very fine, dry powder materials is driving innovations in dry milling methods. Fluidized bed jet mills are a good candidate for nano grinding, because fluidization prevents the dry material from agglomerating. Jet milling with superheated steam enables nano-range particle sizes while also drying the feed material.

Back to Basics Hammer Milling and Jet Milling Fundamentals

网页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 action is caused mainly by particle-particle collisions, so wear to the mill’s internals is less of an issue.
