Science and art of ductile grinding of brittle solids
This suggests that the critical depth of cut for brittle-to-ductile transition lies between 110 and 160 nm, and the use of a negative rake angle can enhance the ductility. Fig. 10 presents an MD simulation of scratching on a (001) silicon surface using a nanoscale spherical contact at (a) 0.5 nm and (b) 1.5 nm.

How to choose the grinding media ball of the ball mill?
Grinding materials can be divided into three types: metallic media, rock mineral materials and non-metallic materials. In addition to considering the production cost, the choice should also consider whether the materials and media will cause pollution. Commonly used grinding media include steel balls, alumina balls, and zirconia balls.

The energy efficiency of ball milling in comminution
In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
