Grinding Circuit an overview ScienceDirect Topics. The circuit comprises a SAG mill 12 m diameter by 61 m length belly inside liners the effective grinding volume two pebble crushers and two ball mills in parallel closed with cyclones The SAG mill is fitted with a 20 MW gearless drive motor with bidirectional rotational capacity
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).
【Ball mill working principle】 High energy ball milling is a type of powder grinding mill used to grind ores and other materials to 25 mesh or extremely fine powders, mainly used in the mineral processing industry, both in open or closed circuits. Ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size, usually, the manganese, iron, steel
