The milling in planetary ball mill is based on pressure, cutting, shearing, and friction forces between balls and material. The most of milling processes apply high energy amount on sample and can destroy the structure of material. ... The acetone was refreshed six times during a span of 3 days.
nally times with acetone. e polymer was then dried under vacuum. Milling was carried out in Planetary Ball Milling machine (FRITSCH PULVERISETTE premium line )at rpm at room temperature. Keeping reverse rotations on, milling can be achieved with much more homogeniza-tion. Sintered corundum . % Al 2 O 3 with steel casing
High-energy ball milling is one of the most suitable methods for the production of nanostructured powders by solid-state reaction at room temperature. NPs can be readily produced by a high-energy ball mill with relatively inexpensive equipment, and there is the potential to scale up production for commercial quantities [27].

The core challenge to grinding a perfect ball is maintaining a precise radius from the tip of the nose back to the shank of the tool. To achieve this, a relief must be ground into the end of the tool, that leads out to an intersection of the outside diameter so that when it gets to the tangent point, creates a perfect radius.
