The vortex movement of sugar cane bagasse carry by a gas is study and the results obtained in the laboratory are compared with the ones simulated through a mathematical model. The formation of the hairspring was classified in three ways, being obtained the speed and fall of pressure in each case through a design of multilevel factorial experiments with a replica. The formation of the normal hairspring was taken as qualitative dependent variable, and as quantitative independent variables, the gas speed, particles size and the mixture concentration were taken, being obtained a correlation that adjusted with 84.64 %. The sample size was determined to compare the values of gas speed and the falls of pressure experimentally obtained with those obtained by the simulation, the experimental results complete a normal distribution and the pattern simulates the process with acceptable engineering error.

Keywords : vortex movement; pneumatic bagasse drying; mathematical model.
