Tumble milling

Tumblei with agglomerate breaker See Sec. 20 Tumbling Mills, for ball mill, rod mill, and vibratory pebble mill which will accomplish mixing along with size reduction.

Tumbling-Mill Circuits Tumbling mills may be operated in normal closed circuit, as shown in Fig. 20-45 or 20-59, or in reverse arrangement in which the feed passes through the classifier before entering the mill (see secondaiy mill in Fig. 20-44 or 20-59).

Percentages of material greater than 50% of the maximum size are about 50% from rolls, 15% from tumbling mills, and 5% from closed circuit ball mills. 

Tumbling mill subclasses primarily are distinguished from one another by the grinding media used and by whether tlie mill is vibrated.

Planetary mills operate at higher stress intensities than tumbling mills. Grinding drums are placed on a rotating bracket and rotate at about 400 rpm such that accelerations of 60 g and over are possible. These mills are used for nanofine milling in batch mode (Fig. 14.8).
