Abstract: A new theory of grading composition, method of grading composition with rolling particles (named MORPE) , is expounded. MORPE shows up the regular conditions of a widerange grading with the lowest viscosity, if the ingredients and the surface of particles are consistent. Not only the paste technological property is the best, but also the grading composition has a wide-freedom for meeting the needs of ballistic and mechanic properties, when MORPE is applied to design of composite propellants. All the results from this study show that the viscosity is lower according with MORPE. Otherwise, the viscosity is higher. It is thought that most close-packed theory is the special case of MORPE.
