Due to its grinding process, all the particles are ground up with greater consistency. Another main benefit of a roller mill vs. hammer mill is that it uses substantially less energy. The roller milling process does not produce excess heat and other energyconsuming effects like hammer milling does. Energy efficiency is becoming a top priority ...
