Dry-grinding of zircon concentrate with 1% added TiO 2 gives a fine-grained powder suitable for the production of close-texture and high-density refractories. The powder for the latter should contain 70–80% fractions finer than 10μ and that for close-texture refractories at least 50–60% of these fractions. The powders can be produced by grinding in a vibro-, ball, or tube …
Mills in different designs facilitate either dry or wet grinding. In wet grinding, the powder is mixed into a liquid beforehand and fed into the mill as a suspension or slurry. Overview of our ball mills and agitated media mills. The classic ball mill Super Orion S.O. is suitable for dry hard crushing and achieves finenesses of under 10 µm.
Ball mills can operate in either a wet or dry state. While milling without any added liquid is commonplace, adding water or other liquids can produce the finest particles and provide a ready-to-use dispersion at the same time. Grinding media comes in many shapes and types with each having its own specific properties and advantages.

The classical grinding process for hard materials in the field of application of the glass and ceramic industry has always been dominated by the ball milling process. However, thanks to the availability of wear-resistant high-performance air separators, this dry grinding technology can now penetrate into much finer particle sizes of up to d 97 = 3.
Wet mills can also be adjusted to reduce the likelihood of wear to the milling media or grinding chamber. If a product needs to be in a dry powder format, after wet milling it requires an energy-intensive drying process. Dry milling techniques, including fluidized jet milling with superheated steam can save this step, possibly also sparing costs.
