RESULTS OF RESEARCH ON FINE CRUSHING

QUELQUES RESULTATS DE RECHERCHES EFFECTUEES DANS LE DOMAINE DU BROYAGE FIN

THE PROCESS OF CRUSHING IS BEST CHARACTERIZED BY THE STANDARD DEVIATION OF GRANULAR DISTRIBUTION. THIS IS EQUAL AT THE LOGARITHMIC SCALE TO THE RECIPROCAL OF THE COEFFICIENT OF UNIFORMITY N OF THE ROSIN-RAMMIER FORMULA MULTIPLIED BY PI DIVIDED BY THE SQUARE ROOT OF 6. THE MATERIALS, PRINCIPALLY SOFT, WITH A LOW N VALUE, ARE EASILY CRUSHED AT THE BEGINNING BUT AGGLOMERATE RAPIDLY. IN THE INITIAL STAGES OF CRUSHING, N INCREASES AND THE BEGINNING OF AGGLOMERATION IS SHOWN BY THE LOWERING OF N. A LOW VALUE OF N RESULTS FROM THE LARGE INDIVIDUAL ENERGY OF FALL OF THE CRUSHING WEIGHT. A LOW VALUE OF N IS FAVOURABLE TO THE PROCESS.
