Ballmill - Wikipedia
Ballmill - Wikipedia

Aballmill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as theballsdrop from near the top of the shell.

What is the direction of the friction force on a rollingball?

Now introduce friction: you have kinematic friction slowing down this point thus make theballroll due to the induced torque. You will have a motion in between the cases of pure sliding and pure rolling. In this case the direction of the friction force is obvious (by definition of the friction).

The photoluminescence of boron nitride (BN) nanosheets exfoliated byballmillingmethod has been investigated. At room temperature, the nanosheets have strong deep ultraviolet (DUV) light emission at 224 nm and weak defect-related UV (∼300 nm) emission. The DUV peak profile slightly changes with the increase ofmillingtime due to the increase of stacking faults caused by the shear force ...
