The main task of primary-, secondary-, and, sometimes, tertiary-stage crushing is to prepare the ore for fine grinding by either wet or dry methods. The minimum size of crushing consistent with economic considerations is in the order of one-fourth to one-half inch (6 to 13 millimetres). Tumbling mills, horizontal cylinders containing grinding media of various kinds, such as rods, pebbles, or steel balls, are almost universally used for fine grinding to secure further comminution. 4, record 1, English, - fine%20grinding

[...] réduction en grains fins de 0 à 500 µm. 5, record 1, French, - broyage%20fin

La fragmentation couvre une gamme d’opérations dont la terminologie habituelle est définie ci-après: [...] broyage (broyeurs) pour la réduction en grains fins ou poudre grossière, calibres limites 0,5 à 6,3 µm; mouture (moulins) pour la réduction en grains fins (1 à 500 µm) Ces deux derniers termes sont courants dans les industries alimentaires, ainsi que dans celle des chaux et ciments. Par contre, les expressions broyage fin ou pulvérisation sont employées plus habituellement, la première dans la préparation des minerais, la deuxième dans les industries chimiques. 6, record 1, French, - broyage%20fin
Record number: 1, Textual support number: 2 OBS
Le stade du broyage consiste à réduire les produits fournis par le concassage tertiaire en grains de taille comprise entre 0, 4-7 µm. Il est généralement complété ou poussé, notamment en matière de minerais métalliques, jusqu'à une taille inférieure à 0, 4 µm, de sorte que ce nouveau stade de réduction, appelé parfois pulvérisation, est confondu avec le stade précédent. 7, record 1, French, - broyage%20fin
