A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

Pigment gives your iris its color. Pigment dispersion syndrome (PDS) happens when the pigment rubs off the back of your iris. The pigment then floats around to other parts of the eye. The tiny bits of pigment can clog your eye's drainage angle. This can cause eye pressure problems. Your eye keeps a healthy pressure by making a fluid called ...

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when intergrinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.

Pigment dispersion syndrome (PDS) is characterized by the dispersion of iris pigments from the iris pigment epithelium and their deposition at the back of the corneal endothelium and in the anterior segment.[1] PDS was first defined by Friedrich E.

In ball mills, the energy input to the pigment dispersion is provided by the rotation of the mill, so that the hard balls within the mill are tumbled with, or onto, the pigment in the mill. Using mills, hardened steel balls are caused to impact vertically upon the pigment charge. Local overheating of the particles can occur.
