Solidsmixing or solids blending is the operation by which two or more solid materials in particulate form are scattered randomly in a mixer among each other by the random movement of the particles. It has long been one of the most widely used industrial, agricultural, and pharmaceutical processes. However, it has been much less developed both theoretically and practically compared to other processes. Therefore, the practice of art often dominates in the operation and design of the mixing equipment and in the assessment of quality of a mixture. The rapid growth of other process industries has made solids mixing a well recognizedbut not yet well developed operation. A considerable amount

“…Moreover, similar to Figure 4a, the data for k λ = 5−11 are overlapped with each other. From Figure 4, the following are indicated: (1) The overlapped data and agreed fitting curves imply the common fully developed state of mixing, i.e., the limit of the mixing state. (2) The evolution stage of mixing can be illustrated by the upward movement of the fitting curves obtained by the linear regression.…”

The mixing of granular particles in rotating wavy wall tumblers is simulated by the discrete element method. The rotating wavy wall is modeled by sinusoidal traveling waves on a fixed circle. Six wavenumbers (k λ = 0, 3, 5, 7, 9, 11) under three rotating velocities (ω d = 0.1, 0.5, and 1.0 π/s) are simulated for detailed analysis. The mixing characteristics are explored by using the difference of dimensionless particle concentrations and the fractal dimension of internal mixing interface, as well as mechanical energies, etc. It is found that the wavy wall tumbler performs more effectively for particle mixing enhancement than the circular tumbler, especially under low rotating velocities. The underlying mechanisms are explained; i.e., the rotating wavy wall can produce a periodic oscillating motion upon the conventional rotating motion of the tumbler. The oscillating motion is especially useful for enhancing mixing under low rotating velocities, although it seems to be overly effective under high rotating velocities since it makes the transition to the centrifugal regime earlier. The results improve the knowledge of particle mixing characteristics in wavy tumblers and are very useful for designing effective mixers.
