Scaling Energy Transfer in Ball Mills: A Scale-Agnostic …
The energy efficiency of ball mills is typically low, with only 1–5% of the input energy used for particle breakage while the rest is lost as heat [18]. The power draw of a ball mill is determined by the charge motion inside the mill, which is influenced by factors such as mill speed, ball filling, and lifter design [19–21].

Computation of charging media for a double compartment cement ball mill
Axial rotation of ball mill provides cascading action of steel balls which crush the raw material due to attrition between steel balls which is known as grinding media. Grinding media is mostly prepared from high chrome steel. Ball mills are efficiently utilized for final grinding of clinker. It grounds the raw mix (clinker) into fine powder.
Ball Mill
The ball mill rotates around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder.
