Ball Mill Operating principles components Uses
The balls which could be of different diameter occupy 3050 of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition.

Rollerball vs Ballpoint Pens A comparisonBlog
Due to the inks used ballpoints and rollerballs have different barrel styles As a ballpoint pen s oil based ink is less prone to drying it does not require a cap so these generally use a twist mechanism or a click mechanism to expose the writing tip A rollerball pen with its water based ink needs its tip kept out of the air and so will generally have a cap to enclose the writing tip.
