The energy efficiency of ball milling in …

Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single-particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically. Since single-particle breakage always produces a product with a distribution modulus of unity ...

Mill Critical Speed Calculation

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...

Mill (grinding) - Wikipedia

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface. These mills typically grind ROM ore in a single stage. A large ...
