Secondary Grinding – Ball Mills. In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½", (65 mm)] typically used ...

Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently a rod mill is the right machine when a steep particle size distribution curve is desired. A product with 80% minus 500 microns can be obtained in an economical manner.

In a tower mill steel balls or pebbles are placed in a vertical grinding chamber in which an internal screw flight provides medium agitation. The feed enters at the top, with mill water, and is reduced in size by attribution and abrassion as it falls, the finely ground particles being carried upwards by pumped liquid and overflowing to a classifier.

These machines perform by applying velocity to the incoming mineral. Typically, crushing velocities below 250 fps (75 mps) are crushing speeds that can be applied to feed sizes from 4" (100 mm) to approximately 1/2" (13 mm). When the feed size is smaller than this, it has a low mass value.

Tumbling mills (Rod mill) In a rod mill, much of the reduction is done by rolling compression and by attrition as the rods slide downward and roll over one another. The grinding rods are usually steel, 25 to 125 mm (1 to 5 in.) in diameter, with several sizes present at all times in any given mill. The rods extend the full length of the mill ...

ROD MILLS Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to …

Capacity: 0.5-500TPH Feed Size: ≤25 mm. Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding.

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.
