Back to Basics Hammer Milling and Jet Milling

Back to Basics Hammer Milling and Jet Milling

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

Ball Mill Loading Wet Milling Paul O Abbe

Ball Mill Loading Wet Milling Paul O Abbe

Charging a Wet Mill The general operation of a grinding mill is to have the product impacted between the balls as they tumble. Unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. As with dry milling there should be at least 25 liquid to fill the void space plus a bit more to insure ...
