The results of characterizing the alumina ball size distribution in two mills of a crushing and grinding plant are shown. The mills were unloaded and the ball charge was screened in order to establish the ball size distribution. For both mills, the balls retained during the unloading were compared to the balls retained at the beginning of the process, and additionally, they were compared to the results obtained by the Swebrec adjusted distribution model. In both cases, the experimental data have had a good fit with this model. This practice is important in order to establish the best ball charge at the beginning of the operation and the ball recharge in the steady state.
El presente artículo, muestra los resultados de la caracterización de la distribución del tamaño de bolas de alúmina en dos unidades de molienda de una planta industrial de cemento blanco. En la descarga de los molinos, las bolas fueron cribadas para establecer su distribución de tamaño. En ambas unidades, se compararon las bolas retenidas en la descarga con las existentes al comienzo del proceso, modelando dicha distribución con la función Swebrec. Los datos experimentales mostraron un buen ajuste con este modelo. Esta práctica es importante para establecer la carga correcta de bolas al comienzo de la operación y la recarga requerida en el estado estacionario.
