Advantages of LVT classifiers. The LVT classifier is a fourth-generation classifier, in which separation takes place due to two opposing forces: the centrifugal force due to rotor blades rotation and the drag force due to passage of gases. The particle in equilibrium when these two forces are in balance and equal, determines the cutting diameter.
