A ball mill, which is used to finely grind materials, causes high levels of vibration and sound during grinding operations. The vibration and sound of mills provide significant information about the internal conditions and can be used to estimate the status of the ground material. We developed a simulation model for the vibration of a mill wall ...

This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. Ball velocities in such shaker mills are high, -o m/s. A given reaction, such as amorphization, can typically take place an order-of-magnitude faster in the Spex mill than in the usual vibratory or attritor mill.

Attrition mills effectively mill metals in inert atmospheres, such as in solid-state or mechanical alloying processes, but are not cost effective. Product output is relatively low with attrition mills, compared to large tumbler and vibratory ball mills. Consequently, tumbler ball mills usually are used for production runs of over 135 to 180 kg ...

But, in another investigation, it was shown that d min was about 5 nm when the TiNi intermetallic powder was milled in a high-energy SPEX shaker mill, but only about 15 nm in the less-energetic Invicta vibratory ball mill (Yamada and Koch, 1993). Similar trends were noted for variations in the ball-to-powder weight ratios (BPR).
