Pigment wetting: All of the air and moisture is displaced from the surface and between the particles of the pigment aggregates and agglomerates (clusters) and is replaced by the resin solution.The solid/gaseous interface ( pigment/air) is transformed into a solid/liquid interface (pigment/resin solution).
"Basic Grinding Theory" provides an overview of the general process of grinding . Grinding occurs at the point of contact between an abrasive wheel and a workpiece. Like any other cutting process, grinding removes material in the form of chips. In order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate.
Intelligent control is a class of control techniques, that use various AI or soft computing approaches like neural networks, Bayesian probability, fuzzy logic, machine learning, evolutionary computation and genetic algorithms.
The reason being is when grinding fresh wheat, the flour isn't sifted through after the grinding process. Therefore, the bran and germ are still included in the flour. This is a benefit of grinding your own flour, but the germ contains oil.
