AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill
In ball mills, steel balls or hard pebbles to break particle based on impact and attrition A rotating mill charged with media and ore is lifted against the inside perimeter Some of the media falls and impacts the ore particles at the bottom of the mill The rest of the media cascades and, in the process, creates particle breakage by attritionMetallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig 25 and the actual layout in Fig 9 This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 Closed Circuit Grinding VS Open Circuit GrindingClosed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grindingRaw Material DryingGrinding Cement Plant Optimization
