Ball milling: a green technology for the preparation and
Sorrentino.19 In particular they classify the ball mills in two groups depending on their operation mode: direct and indirect milling. In the rst case rollers or mechanical sha s directly act on the particles and transfer the kinetic energy. In the second case the kinetic energy is rstly transferred to the mill body and then to the grinding medium.

Mechanical Governor (Device), Working Principle, Types and Function of
How mechanical Governor works Mechanical Governor has two balls of equal weights attached to the arms of the Governor. These balls called Governor balls. These balls revolve when spindle of governor rotates. The upper end of the arms is attached with the spindle. This makes the ball to move up and down while rotating with respect to vertical axis.

Mill (grinding)
Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
