Ball mills work well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to .
Contributions to the modelling of the milling process in a planetary ball mill 23 ing impact energy in their study, and they focus on inspecting the collision between the ball and the material to be milled. Iasonna and co. Magini [17] in one of their studies examined energy transfer and power consumption during the milling process.

2. Low Operation Cost. ⑴ High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%. ⑵ Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime ...
ball mill circuit "classification system efficiency" (CSEff). It is the percentage of "coarse" material in the ball mill, relative to the target grind size, typically the circuit target P80. The "coarse" material is targeted for further grinding, while the "fines" have reached target product size or finer.

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
