    The grinding method has a direct impact on the surface properties of the particles and hence the polymer–filler interaction, mixing behavior, curing characteristics, and mechanical properties can be tailored by altering the grinding method. For example, cryogenically ground rubber particles have a smoother surface as compared to grind rubber particles. Hence, powder obtained through ambient
