The typical closed ball mill circuit to which CSE analysis can be applied is shown in Fig 1 The extreme importance of the circulating load ratio solids tonnage through the mill vs the circuit in determining circuit productivity was demonstrated by Davis 1925 and published by Gaudin 1939 as shown in Fig 2 The circuit production rate.
Ball mill mill open circuit Closed circuit crushing is recommended for single stage grinding as there is greater control over size of feed going to the one ball mill Open circuit crushing is advantageous when using twostage grinding due to the ability of the rod mill to handle an oversize feed product.
