Impact mills use revolving hammers to strike incoming particles and to break or fling them against the machine case. In jet mills, particles strike each other as they are transported in a stream of air or steam. For the initial reduction of large materials, a rotating drum propels the feed into the air where the pieces strike each other and ...

9.2 Sand Dunes. Sand dunes are hills of sand built up and shaped by the wind. They range in length from 1 m to tens of kilometres and in height from a few tens of centimeters to over 300 m. Sand dunes come in a variety of forms, and there are several classification schemes for dunes.

The classification on a scale of increasing mill energy is: horizontal ball mill, attritor, planetary ball mill and vibrating ball mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial tumbler ball mill.
