Grinding can be done in batches, or in a continuous flow process (which is more common). First, material enters one end of a vibratory grinding mill drum into horizontal cylinders. Then, the mill uses a vibratory motion to mix and grind the particles, with operating speeds ranging from 800 to 1500 rpm. Typical vibratory mills use attrition …

The abrasion of the hammer slice can cause the rotor of the feed-grinder to lose balance and then make the grinder vibrate. A virtual prototype (VP) based on the rotor of an SFSP112 x 30 feed-grinder was set up by using MDT and vN4D for investigating the relationship between the abrasion of the hammer slice and the vibration of the rotor.
