• Mill power draw models

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.

O I SKARIN N O TIKHONOV CALCULATION OF THE. 80 is accepted based on the required grainsize characteristics .

• Charge behaviour and power consumption in ball mills ...

· For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the noncircular balls falls off rapidly. This reflects the increasingly well spread out and dilated charge for the noncircular particles.

• Bond formula for the grinding balls size calculation

· We draw your attention, a larger grinding balls need to use for future loads. As practice shows, the difference between the grinding balls average diameter in mill and loaded grinding balls diameter is 1015 mm. In our example, the grinding balls diameter needed to load into the mill must be equal to 4050 mm. Let's sum up.

• THE OPTIMAL BALL DIAMETER IN A MILL

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
