Inks used in flexography and gravure , which have thin, volatile, solvent-based vehicles, are commonly produced in ball mills. The longer the slurry remains in the mill, the more finely the particles are broken up. Often, geometrical shapes other than spheres can be utilized.

A ball mill is a type of mill used to grind and mix materials to be used in processes for mixing minerals, paints, pyrotechnics, ceramics, and selective laser sintering.
In [169], the process is described to produce spherical fragile boron particles of 4–100 μm by ball-milling in a solution of fluorocarbon binder Fluorel®. The work demonstrates that the spheres of the required size and hardness can be produced by adjusting the treatment parameters of the mill.

The Rise of Ceramic Sphere Milling Machines Ceramic sphere milling machines have gained prominence due to their unique capabilities in shaping and finishing ceramic materials. These machines are designed to mill ceramic spheres with unparalleled precision, resulting in products that meet the highest quality standards.
The first method is simple mechanical wet-milling using a planetary ball mill and spherical grinding media. Spheres of yttria-stabilized zirconia (YSZ) were used as grinding media because of its excellent hardness and chemical inertness properties [25].YSZ is a very dense ceramic material that transfers high impact and shear energy into the biochar as it is milled.
Milling mechanism composed of a high-energy ball mill and a dispersion tank. By means of a displacement pump, the nanoparticles resulting from the milling process are kept in constant recirculation from the dispersion tank to the mill cabin.
Grinding Media Size and Weight: The size and weight of the grinding media can dramatically influence the milling action. Balls made of more dense media can produce a coarse grind, while lighter balls lead to a finer grind. The choice of media depends on the material being milled and the desired particle size.
Grinding balls are small spheres (although they are not usually perfectly spherical) that can be used for attrition and mixing of products such as powders. Our standard product range includes balls made of alumina and zirconia, as both of these technical ceramics offer ideal purity and density for grinding hard products.

For pure MCMBs without ball-milling, gray areas of carbon spheres and black areas between spheres derived from viscous phase can be seen clearly, which verified the sintering mechanism reported by Norfolk et al. [12]. With increasing the ball-milling time, the amount of carbon spheres reduced and the size of grains decreased.
Solvent free derivatization has been achieved by a simple ball mill grinding procedure to functionalize glassy carbon spheres with anthraquinonyl and nitrophenyl groups using aryl diazonium salts. Grinding facilitates the mechanical activation of the carbon substrate material with the creation of active centres and may induce the decomposition of the diazonium salt.
As soon as I switched out the alumina, my BP improved. I used my alumina spheres to mill charcoal by itself, and also to mill BP. After a long time, I noticed that the surfaces of the media had developed 'craters' from the repeated impacts. I was concerned about the degrading media forming grit that could cause an ignition, and stopped using it ...

The results indicate that larger spheres with diameters of about 2–2.5 mm are created after 20 h of ball milling. The formation of such spheres is mainly due to sphere-to-flake or sphere-to-sphere welding. This welding is not complete, leaving large pores and curved voids in the spheres. The average grain size of such spheres in 10–100 nm.
