This manuscript presents an experimental evaluation of the grinding of biomass pellet samples using ball mills. These samples are the torrefied and white wood pellets. Both samples were deagglomerated with water to determine their original particle size before the pelleting process using RRSB model.

Pellets will leave the pellet mill at temperatures as high as 80 to 90 degrees centigrade and moisture contents are high as 1718%. For proper storage and handling of the pellets, their moisture content must be reduced to 1012% and their temperature to about 5 degrees higher than the atmospheric temperature.

For eucalyptus pellets, the planetary ball mill produced the finest distribution (d′ 493 μm) followed by the BWI (d′ 541 μm), while the opposite trend was observed for mixed wood pellets (d′ 628 μm for planetary ball mill, d′ 530 μm for BWI). The knife and ringroller mills show little impact on the premilled particle sizes.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Moreover, floatability of each fraction ( 400, +400325) in mill feed and discharge was studied. Results indicated that, the floatability of all fractions in the mill feed was more than the mill discharge. It means that electrochemical interactions between the grinding media and Chalcopyrite let to decrease in floatability of material.

In some cases, ball milling is used before HPGR when the pellet feed is too coarse or too hard for saving grinding costs and improving balling characteristics of the pellet feed. For example, a wet ball mill plus a HPGR circuit was installed in WISCO Minerals' pellet plant in China to pretreat Brazilian specularite concentrates.
