The requirements in energy consumption in grinding increases as the moisture level in the material becomes higher. This is due to higher moisture contents that make the process of deforming and cutting the material more intensive [7,9,14]. Therefore, the grinding energy has to be analyzed to reduce inefficient energy consumption.
