Fine grinding or milling reduces the particle size down to as low as micrometer (µm) (4 x 105in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process.

+

Nd–Fe–B nanoparticles have been obtained by using surfactantassisted ball milling and subsequent sizeselection technique. Structural analyses show that nanoparticles with two particle sizes around 10 and 100nm were obtained. The partially amorphous Nd–Fe–B nanoparticles give their roomtemperature coercivities around and for the small and large nanoparticles, respectively.

This method determines the resistance of aggregate in flexible base material to disintegration in the presence of water. The test provides a measure of the ability of the material to withstand degradation in the road base and detects soft aggregate that is subject to weathering. The result of this test is the Wet Ball Mill (WBM) value.
