jet mill, the same two opposing force –mass force and drag force-are acting on the particles. Mass force is the force exerted on the particle by acceleration due to gravity, inertia, or centrifugal force. Drag force is the force exerted on a particle by the surrounding medium as affected by its aerodynamic properties. In the centrifugal air

CASTINGS & FORGINGS Centrifugal Casting Centrifugal casting, sometimes called roto-casting, is a metal casting process that uses extremely high centrifugal force ("G" Force) to molten metal to form cylindrical parts. This differs from most metal casting processes, which use gravity or pressure to fill the mold. Centrifugal casting is used to produce axi-symmetric parts, …

Milling is accomplished by impact and shear forces. The rotating charge of balls and milling product form a vortex at the upper end of the stirring shaft, into which the milling product and balls are drawn. The milling product is impacted by balls traveling in various trajectories that collide within the dilated charge of medium and powder.

The media media most used in all milling applications are made of zirconia. But if the purpose of ball-milling is to blend materials softer than zirconia, alumina media is recommended to avoid breaking the dispersed powder. Using grinding balls with different diameters, 3 or more, improves the particles dispersion in the ceramic slurries.
