The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.

A ball mill and a tumbling mill are both types of grinding mills used to reduce material size. We mainly use a ball mill for mixing and grinding processes. In contrast, we generally use a tumbling mill for finer material reduction. What are the balls? Ball mills grind materials into an extremely fine form.
Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis. But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size. These forces come into play as

The ball grinding medium also slips during the rotation of the cylinder. The media slip will grind the material. When the grinding of large particles, in order to effectively use the grinding effect, the grinding body cylinder with a compartment plate separated into two sections, that is, double bin.
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
Grinding (Rod) or (Ball) Mill TYPE D Has single weld, triple flanged, construction which means the shell is furnished in two sections, flanged and bolted in the center. All flanges are double welded as well as steel head to shell, note design. Tumbling Mill (Rod or Ball) Mill TYPE E Has quadruple flanged construction. This also furnishes …

Ball Design Factors Size and Mass. Importance of size: Taggart (1927) stated "Size of balls should be proportional to the work to be done, i.e. the size of the particle that must be broken by impact, hence coarse feed and hard ores require larger balls than finer feeds and softer ores." The 9 to 10 m (30 to 33 ft) SAG mills now in wide use ...
