Nov 13, 2006 The diameter of the drum was 0.8 m. The rotation speed was 37 rpm when preparing the seeds and 47 rpm when balling the green pellets. The balling was done in three steps. First, the dry balling drum was conditioned to relevant balling humidity by balling a small batch of the studied material for about 5 min, after which the material was discarded.

adding between 1 and 10 percent limestone to the ore and binder before pelletization. Pelletization generally is accomplished by tumbling moistened concentrate with a balling drum or balling disc. A binder, usually powdered bentonite, may be added to the concentrate to improve ball formation and the physical qualities of the "green" balls.

The examples are summarized in the following table. Taconite concentrate which has been dried to remove substantially all moisture (about 9-10 percent by weight) and having a particle size of 90 percent minus 270 mesh is mixed with the bentonite binders shown in the table in the amounts shown and passed to a balling drum.

Pelletizing Lends a Hand in Recovering Nickel Dust
Rotary drums, sometimes called balling drums in this context, also serve as an effective pelletizing tool. The rotary drum consists of a large, rotating drum set on a slight angle to assist material in moving through the drum via gravity. Again, material and binder are continuously fed to the unit, where rotation and the binder promote layering ...

Jan 01, 2012 Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green pellets. The green pellets are screened to 9–11 mm diameter. The oversize is crushed and fed together with the undersize back to balling.
