The feed material was dry batch milled for selected periods ranging from 3; 5; 15; 30–90 min. For all the batch tests, the mill feed was kept constant at 1941g and after each duration the mill was stopped and the contents offloaded. This was then followed by separation of the product from the grinding media on a wire mesh.

A mill is charged with media (small beads or spheres) and activated by a high-speed agitator shaft to separate the individual particles. When the agitator rotates, it transmits kinetic energy to the media. When the material is pumped through the mill, this energy acts on the solids suspended in a liquid (slurry) to tear them apart (shearing) or ...

Zirbeads will grind-up lower density media such as zircon and glass beads, contaminating the product and causing undue wear on the mill. The wear rate of Zirbeads is one half to one third that of other dispersion media. See "Typical Properties". A 21% reduction in diameter allows twice as many beads. See "Suggested Charge Weights".
