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.

Ball-milling is the most common process for graphene synthesis. In several studies, the mill was run in different features [,, ]. Edge-carboxylate graphite (ECG) was produced by ball milling and analysed by using a finite-element method. The ball-mill machine runs 48 times at 500 rpm, each time with 50 min of ball-milling and 10 min of rest.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.

Wet milling, a core aspect of the wet grinding process, involves breaking down materials in a liquid medium. The wet ball milling process, a popular choice in many sectors, employs a ball mill to achieve a fine grind. This method is particularly effective for materials that are too hard for standard milling. Steps in Wet Ball Milling Process
