# ball mill larger or smaller balls

How can one select ball size in ball milling and how much.The ball size to be decided based on the impact energy requirement. Bigger balls helps in size reduction if the feed particles are bigger in size like chunks. If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls.

size of grinding ball is 25 mm or bigger. As mentionned by various authors (Jankovic, Valery and. La Rosa, 2003; Gao and Holmes, 2007), conventional ball milling was discarded because of its very poor energy efficiency caused by those larger balls. Therefore, new technologies as stirred mills were developed to grind.

### Classification liner for the second chamber of the ball mill | Industrial .

The second chamber of a ball mill is mainly for fine grinding. Therefore, using small balls was known to be more efficient as this increases the surface area of media and improves the grinding effect. For the conventional mill using a liner with lifter, however, it was difficult to reduce the ball diameter drastically because the.

The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the.
