We investigate the competition between granular mixing and segregation in a sphere rotating and rocking on two orthogonal axes. Operation corresponds to the continuous-flow regime and the flow within the sphere is three-dimensional and time-periodic. Experimental results are organized in a frequency/amplitude phase diagram showing modes of segregation ͑band formation/no axial bands͒; segregated bands are remarkably robust and survive rocking amplitudes as large as 60 degrees over a wide rangedoi:10.1103/physreve.68.061303 pmid:14754197 fatcat:nlmtail2u5etxknpmdygqzwthq
