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

The configuration of the attrition mill's agitator system causes constant motion of material around the tank. The area of greatest media agitation is located approximately twothirds the radius from the center shaft (Figure 2). In productionsized units for wet milling, a pumping circulation system augments the movement. As can be seen in

The opening sizes of the hammermill screens used were 250 μm. In addition, peppercorns were passed through the hammer mill two or three times to produce particles that were comparable in size to those generated using cryogenic grinding (see Section ). The hammer mill was cleaned between passes to avoid crosscontaminating different samples.
