I give you a link to 2 old research papers answering your question in detail when there compare test results of a Hardinge ball mill and a Chilean or pan mill. The ball mill consumes around 30% less power. The ball mill has proved itself to be a much superior grinding machine as it produces around 50% more particles in the sizes of 60 to 200 mesh.

In this study, silica nanoparticles (SiO2 NPs) were fabricated using a handmade ball mill as a novel, simple, rapid, costeffective, and green approach. The solgel method was also used to produce these NPs as a comparative method. The SiO2 NPs produced by both methods were characterized using highresolution transmission electron microscopy (HRTEM), dynamic light scattering (DLS), energy ...

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
