ball mill for preparation of composites

Mechanical ball milling also known as ball milling is a desirable choice because it is suitable for massive and continuous preparation of uniform morphology crystals that maintained the original crystal form

The velocity of milling balls can be calculated using 2 V b 2 R ⋅ Ω 2 r − r b 2 ⋅ ω 2 ⋅ 1 2 ⋅ ω Ω where R is the distance between the center of sun wheel disk and milling vial center and Ω is the angular speed unit radians per sec of the sun wheel disk of a planetary ball mill r and ω are the radius and angular speed of milling vial and r b is the radius of milling ball
