THE OPTIMAL BALL DIAMETER IN A MILL

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

The long processing time is among the reasons for low efficiency in the implementation of conventional conching and ball‐mill techniques. In this study, the time‐dependent variation of the moisture, particle size, and water activity of dark, milk, white, and compound chocolate (cocolin) samples were modeled using polynomial regression analysis.

Ball‐Mill‐Exfoliated Graphene: Tunable Electrochemistry ...

Abstract. A simple wet ball‐milling method for exfoliating pristine graphite to graphene nanosheets is proposed. The surfactant of cetyltrimethyl ammonium bromide is utilized to greatly improve the exfoliation efficiency of graphene nanosheets. Variation of the ball‐milling time is an efficient way to control the size and thickness of graphene nanosheets, as well as the level of edge defects.
