high temperature pulverization

Pulverizer - Wikipedia

A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry. Both types of mill include liners that protect the cylindrical structure of the mill from wear.

Improvement of pulverization efficiency for micro-sized

Nov 02, 2019  The compressed air generated from a high temperature of 150° C introduces the pulverization energy of the jet stream to have the ceramic powder grind under 78 μm, which maximize efficiency. The grinding pressure of the conventional cooling air jet mill system is the same as the developed uncooled air jet mill system.

Cero - pulverization vs vaporization VS Battles Wiki

Anyway, my point is that there is enough evidence to support very high temperatures being generated by even reiatsu that is not flame based. I have stated in my blog on why I support pulverization. But I have also stated that there is actually evidence to support vaporization as well. I just want calc group member thoughts on this shit.
