Mechanism of action: Hammer mills reduce the particle size of materials by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has low kinetic energy, whereas the hammer has high kinetic energy. The transfer of energy resulting from the collision fractures the grain into many pieces.

MECHANISMS AND LAWS. ... Hammer mills cannot be applied with sticky, fibrous, and rigid materials. ... At low speeds, the ball rolls over each other, and attrition (rubbing action) will be the predominant mode of action. Hence, in the ball mill, impact or attrition or both are responsible for a decrease in size.

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.

Mechanism of action. The exact mechanism of action of ibuprofen is unknown. However, ibuprofen is considered an NSAID and thus it is a non-selective inhibitor of cyclooxygenase, which is an enzyme involved in prostaglandin (mediators of pain and fever) and thromboxane (stimulators of blood clotting) synthesis via the arachidonic acid pathway. 27
