Temperature progression in a mixer ball mill SpringerLink

Apr 22 2016 · Mechanochemistry using ball mills is a promising technique 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 dissipated as heat .This is why measurement and control of the temperature in the ball mills is important for example if heat-sensitive products are formed that The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces created by the rotation of the bowl around its own axis together with the rotation of the turn disc are applied to the powder mixture and milling
