Aerofall Mill. The aerofall autogenous and semi-autogenous air swept mills are additional solutions for dry grinding. These mills are typically very large in diameter and very short in length achieving high throughput. The material is lifted to great heights using lifter bars and dropped with forceful impact onto itself in the mill. The mill system would include separators and cyclones downstream from the mill to return rejected material to the mill, if needed. The aerofall mill is good for grinding abrasive materials with high moisture content and large feed size.

CONT

Quarried material is taken by conveyor or trucks to the processing plant where, if it is in rock form, it will be crushed to ensure that it is of a suitable size to pass by conveyor to the stockpile. From the stockpile it is fed, again by conveyor and a controlled amount of water to a rotating aerofall mill, which contains heavy metal liners, which help tumble the rock onto itself, crushing through various screens, spiral classifiers and washing tanks to remove unwanted impurities.

Un broyeur à boulets comprenant : une virole cylindrique en forte tôle [...]; les fonds d’entrée et de sortie munis de tourillons de grand diamètre [...] Le fond d’entrée et la virole du broyeur sont protégés par un blindage en acier spécial résistant à l'usure. [...] Le blindage de la virole est le plus souvent du type classant releveur, c'est-à-dire qu'il classe les boulets en ordre de taille décroissante.

DEF

Ball mill in which diameter-to-length ratio is of order 1 : 2 1/2. Usually loaded with large pebbles or lumps of ore as crushing bodies.

OBS

The ball mill differs from the tube mill by being short in length; its length, as a rule, is not far from its diameter (...). The tube mill is usually long in comparison with its diameter, uses smaller balls, and produces a finer product. (...) The pebble mill is a tube mill with flint or ceramic pebbles as the grinding medium and may be lined with ceramic or other non-metallic liners.
