    "abstract": "We propose a continuum description for the axial separation of granular\nmaterials in a long rotating drum. The model, operating with two local\nvariables, concentration difference and the dynamic angle of repose, describes\nboth initial transient traveling wave dynamics and long-term segregation of the\nbinary mixture. Segregation proceeds through ultra-slow logarithmic coarsening.",
