Uses of fluid energy mill ball mill

Uses of fluid energy mill ball mill

A fluid energy mill requires considerable energy, primarily in the form of compressed air, which is the major cost component of the operation. To improve the economics of the fluid energy grinding, especially for hard solids, it is helpful to pregrind in a conventional mill and use the product as feed stock for the jet mill
