air ,. . classification The Comex air classifier has been developed at SINTEF/NTNU laboratory in Norway. The feed material enters the classifier mixed with an air stream, through a vertical pipe positioned at the bottom of the classifier. The particle stream entering the classifier is dispersed around a static distribution cone, where coarse particles immediately begin to settle in the lower velocity air stream. Thse particles are rejected towards the conical outlet and fall down to the bottom part of the classifier. As they are falling to the bottom of the classifier, they pass through an...

fine., . classification The fine particles are swept up towards the classifying rotor, while the coarse material is discharged from the classifier, by gravity, through the coarse fraction outlet. The finer fractions presented to the classifying rotor, are selected or rejected according to the rsultant of a positive air drag force opposing a ngative rejecting centrifugal force, developed from the rotor speed. The selected fine fraction flows through the rotor and is discharged from the classifier through the air outlet, togetherwith the air flow. The fine fraction is separated from the air...

fin© classification Energy saving potential Due to it's unique design, the Comex air classifier provides high classification efficiency and simultaneously gives a very low pressure loss during opration. This is of critical importance when the overall energy for material processing is considered. In some applications for industrial minerais, the Comex classifiers provided a production increase of 80 - 120 % after replacing older classifiers. The table below shows some examples of material processing using Comex air classifiers. Considering closed circuit grinding when the air classifier is...

classifier filter PC secondary cyclone product filter product Configuration of the air classification circuit Example of the multiple size production plant Applications Comex air classifiers can be applied to processing of various materials having diffrent physical properties. High classification efficiency can be obtained with materials that are difficult to disperse. Furthermore, thanks to its unique construction and thus low wear rate of moving parts, this type of classifier provides a high application potential for processing abrasive materials and high purity products. The ACX...

fins classification related to particle sparation where the feed material is to be classified into coarse and fine fractions. The main advantage of the efficient classification process is then expressed in the particle size distribution of the coarse fraction being free from the fine grains. High recovery of the fine stream is another important parameter being critical for the production rate of a circuit. The second basic classifier configuration is related to the closed circuit grinding with milling equipment. Comex air classifiers are often used in grinding circuits where their high...
