The fluid bed jet mills are also different from the loop and pancake mills in that they have grinding nozzles that are directly opposed rather than tangential to the mill body. The direction of the air nozzles produces additional advantages outlined in the case studies of the Fluid Energy Roto-Jet mills described below. Graphite Grinding System

In fluid energy milling, a DoE is typically built using grinding pressure, pushing pressure, and feed rate as input variables, and the size distribution of the product as the response. Generally, for fluid energy milling, a finer particle size is obtained by reducing the feed rate of material into the mill and by using higher pressures [ 20 ].
