Jun 02, 2020 A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the

Is it possible to make an alloy of every metal? - Quora

Answer (1 of 4): No. All alloys are mixtures. Not all mixtures are alloys. Some metals aren't all that keen on being mixed with each other. But if you stir them together energetically, and cool them quickly before they separate much, you will get a solid mixture. A fairly useless solid, except

Temperature progression in a mixer ball mill

Mechanochemistry using ball mills is a promising tech-nique with applications in organic and inorganic chemistry as well as material sciences [1–4]. During ball milling, up to 80 % of the energy that is generated in the mill is dis-sipated as heat [5]. This is why measurement and control of the temperature in the ball mills is important, for
