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

Jet Mill sales and supplys. Grind to less than 5µm

2021-5-20  Jet Mills. A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
