### cement grinding optimisation - CiteSeerX

The established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some 'efficiency factors' as described by Rowland (1975). Bond's equation describes the specific power required to reduce a feed from a specified feed F80 to a product.
