Mill grinding - Wikipedia A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting with W as grinding work in kJ/kg c as grinding coefficient dA as grain size of the source material and Ball mills normally operate with an approximate ball charge of 30%. A SAG mill is usually a primary or first stage grinder.
