The grinding media is actually alumina particles held in place by an SiO2 glass phase. Sizes from 400 microns to over 1 inch in beads, balls, satellites (ball with bands) and cylinders. Low to medium cost, small sizes are more costly. Fused Zirconium oxide Grinding Media (sp.gr. 3.8) Smooth surface leads to low mill wear and longevity.

Milling also produces a rough, grooved surface, which will increase the existing pavement surface area when compared to an ungrooved surface. The surface area increase is dependent on the type, number, condition and spacing of cutting drum teeth but is typically in the range of 20 to 30 percent, which requires a corresponding increase in tack coat (20 to 30 percent more) when compared to an

A disadvantage to dry ball milling in conventional concrete is that the rough aggregate would be rounded somewhat. In a nonconventional concrete, however, this type of milling might lead to better pouring properties and less particle–particle interaction among the chunks of aggregate.

Ultrasonication is an efficient means for the wet-milling and micro-grinding of particles. Besides dispersing and deagglomerating, the wet milling is an important application of Hielscher ultrasonic devices.. In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: mills (e.g. ball mills
