## Grinding Mill Circulating Load Calculation

#### Plant performance improvements

Definitions and example calculation 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 increases with ...

#### VALIDATION OF A CLOSED CIRCUIT BALL MILL MODEL Alex ...

The effect of circulating load on grinding capacity has long been understood. In a report published in 1925 [4], Edward W. Davis, first demonstrated the fundamental relationship between the new feed rate and the circulating load in a closed grinding circuit. His original graph of the relationship (Figure 1) has been reproduced with various modifiions in many publiions. According to this ...

#### Determining Specific Grinding Rate of Coarse

where P is mill power and M mass of material in the mill (particles, not grinding media). (Likely units of S 1 E in this case might be kg/J). For a continuous mill, the conversion gave: S 1τ = 𝑆1𝐸(P/F) (5) where F = BMF calculated by multiplying the new feed rate by the circulating load ratio, which is
