The effect of ball size on copper powder particle morphology in drytype milling was studied using a planetary ball mill. Spherical copper powders were obtained by ball milling at a high rotation speed and with a ball diameter of 1 mm. The experimental results suggest that the particle size and morphology can be controlled by changing the ...

To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour. Your nitrate should be light and fluffy. If not, continue grinding it 'til it's fine powder with no chunks or grains.

The original powder combination was then charged and sealed with 50 stainless steel balls in a stainless steel vial (SUS 316, 250 mL capacity) (SUS 316, 10 mm in diameter). The balltopowder weight ratio was maintained at 20:1. Ball milling experiments were done in a high energy planetary ball mill at a rotating speed of 300 rpm.

Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
