Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (m) (4 x 10-5in.) 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

Emissivity Coefficient Materials

The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.
