Mill (grinding)  Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the . Ball mills normally operate with an approximate ball charge of 30%. Ball mills
