Mixing of granular media in a drum mixer

2016-9-21  Although this laboratory size drum mixer is not of the scale of an industrial mixer, it is sufficiently large to demonstrate the mixing process. To analyze nonadhesive contact between particles, the granular media consist of two batches of spherical limestone pellets. The first batch has a mass of 16.3 kg, and each pellet has a radius of 5 mm ...

Axial segregation of granular media rotated in a drum ...

In the traditional axial segregation effect, a homogeneous mixture of different types of granular material rotated in a drum mixer segregates into surface bands of relatively pure single concentrations along the axis of rotation. This effect primarily has been studied with respect to the initial segregation. However, the initial pattern is not stable, but evolves in time with continued ...

Numerical analysis of mixing of particles in drum

2016-3-1  A mixing index (ψ) is defined to quantify the extent of mixing throughout the drum mixer.The working space was virtually divided into cubic cells to assess the mixing in different parts of the mixer. The element size selection or discretisation of the domain is based on spatial averaging principle .Cleary et al. suggested that the edge length for the domain discretisation should be an integer ...

Cohesion-driven mixing and segregation of dry

Granular segregation is a common, yet still puzzling, phenomenon encountered in many natural and engineering processes. Here, we experimentally investigate the effect of particles cohesion on segregation in dry monodisperse and bidisperse systems using a rotating drum mixer.

Velocity Fluctuation Measurements of Granular Media

Abstract. The concept of velocity fluctuations (granular temperature) is important in describing the flow and mixing of granular particles. Recent theories model the axial segregation of granular mixtures in a horizontal rotating cylinder, as an interaction between the surface flow and the random diffusive motion of granular particles.

2019-12-12  The discrete element method (DEM) offers the possibility of understanding mixing processes at a microscopic, particle level. In connection with previous studies, DEM is used in this work to investigate the mixing of monosized spherical particles with blade speeds in the range 2−100 rpm. Recirculating flows are observed in both horizontal and cylindrical sections of the bed, providing a ...
