Planetary ball mills are used for the pulverization of soft, hard, brittle, and fibrous materials in dry and wet mode. Extremely high centrifugal forces result in very high pulverization energy and therefore short processing times. Planetary ball mills are ideally suited for tasks in research like mechanochemistry (mechanosynthesis, mechanical ...

F_ty + F_g = 0. F_ty = F_g. That last equation shows that the vertical component of the force of tension is equal in magnitude, but opposite in direction, to the force of gravity. There isn't a normal force because normal force requires contact with a surface. In that second example, the ball on the string is just moving through the air.

The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...
