Reviewing on the working mechanism of horizontal roller mill based on the rule of layer material crushing

There are two classical equations in the research field of granularity properties, commonly known as Gates-Gaudin-Schahamann granularity equation (referred to as GGS) and Rosin-Rammler-Sperling granularity equation(referred to as RRB). If we combine the RRB or GGS with the unified energy granularity equation, we can get the energy equation which is more close to the actual production. Through the analysis of the working mechanism, we can get the reason of energy saving and energy efficiency.
