This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closedcircuit ball mills. Parametric and nonparametric deconvolution techniques were evaluated. Both techniques allowed for direct RTD estimates from inlet and outlet tracer measurements in the mills, with no need for mass balances nor assumptions to correct the effect of the ...
