Attrition Crushing: Abrasion crushing is the consequence of material being subjected to the grinding action, often between two rotating surfaces or media. This is the reason why there is a decrease in particle size due to abrasion and friction. This method is popularly employed in fine grinding processes such as ball mills or rod mills.
