Classification is a process of dividing a particle-laden gas stream into two, ideally at a particular particle size, known as the cut size. An important industrial application of classifiers is to reduce overgrinding in a mill by separating the grinding zone output into fine and coarse fractions. Many types of classifier are available, which ...Web

Particle classification occurs when particles are separated according to their relative sizes and/or densities. Classifiers employing liquid as the separating medium have existed for more than a century (Epstein, 2003).
