Our high efficiency industrial air classifier for cement are designed in such a way that the material-tobe- classified arrives at the distribution plate by two diametrically arranged feeding chutes. Due to the high speed of rotation, the material is then pushed to the side walls. In this process, any possible agglomerates disintegrate before the dissolved material falls into the classifying area below. In falling, the material is caught by a horizontal airflow which carries the smaller particles through the rotor blades into the rotating cage. From there, they are either carried to cyclones or are classified as fine material through a filter system. During this classi fying process, heavy particles are not caught by the air flow but fall into the coarse material cone.
