Centrifugal motion returns coarse particles to the hammers. The whizzer blades shown on the Raymond vertical mill (Fig. 2049) have a similar centrifugal effect, throwing coarse particles to the wall of the chamber, where the lower boundarylayer air velocity allows them to fall back to the grinding zone.

The pressure arrangement of the grinding rolls is hydraulic. The mill feed is introduced into the mill from above, falling centrally upon the grinding plate; then it is thrown by centrifugal force underneath the grinding rollers. A retention ring on the periphery of the grinding table forms the mill feed into a layer called the grinding bed.

The grinding balls in the planetary mills acquire much higher impact energy than is possible with simple pure gravity or centrifugal mills. The impact energy acquired depends on the speed of the planetary mill and can reach about 20 times the earth's acceleration.
The critical speed of a ball mill is the speed at which the centrifugal force is equal to the gravitational force acting on the grinding media, resulting in the material being ground to a fine powder.
The grinding chamber The vertical cylindrical grinding chamber is the heart of the TowerMill where comminution of mineral bearing ores takes place. Like all agitated media mills the grinding chamber is charged with spherical grinding media. The media can be either steel or ceramic balls, depending on the downstream process and end product desired.
