The working of Classifier is based on the natural laws of centrifugal, gravitational and flow forces that bring about the classification in elements of different sizes. It has excellent ability to handle various types of materials including quartz sand, gypsum, lime, cement, iron ore, coal and other raw materials. Acknowledged in the global market place for its wear free confined air seal, smooth drive and unbreakable strong lining, this equipment provides maximum economy even during maintenance.

Successful Installation in
Our high efficiency air classifiers are an assurance
for the quality of materials such as:
- Raw meal
- Coal / Petcoke
- Iron one
- Quartz sand
- Graphite / Fly ash
The Clever Concept
Our high efficiency air classifiers 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.
The classifier’s focus:
its classification effect
An air classifier divides material flow into two parts. One of them consists of fine material, the other one of coarser parts. Centrifugal, gravitational and flow forces impact on mass elements which are of di"erent sizes and use natural laws to bring about classification. The “tromp curve“ illustrates how e!ciently the materials are classified: The lower the deviation from the vertical, the more precise the sharpness of classification. The lower the deviation from the horizontal line, the greater the classification effect.
