ball mill section). As an example, Table 1 presents AG/SAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi, the calculated figures would suggest that the AG/SAG mill is very inefficient, while the ball mill is significantly more efficient than Bond would predict. Figure 1 presents
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
