NEA DC Highly Efficient Classifier 

 

The NEA DC classifier is a highly efficient air separator which can be excellently directly integrated into existing grinding, classification and separating processes. The DC classifier feeds the product to be classified to the process air. As a consequence, the product no longer needs to be separated prior to classification.

Maximum yields with Deflector Classifier DC

The feed material is fed to the classifier from below with the process air. The deflector ring in the classifier enables the guidance of the product from above to the classifier wheel. Simultaneously, the process air flows radially into the classifier wheel. Uniform classification conditions and the use of the entire classifying zone enable maximum yields with minimum energy requirements.

However, the NEA DC classifier is not only suitable for combination with new systems. It also improves the quantity produced and product quality for existing systems such as ball mills and micronizers which are equipped with older construction style classifiers.

The increase in efficiency of the classification process relieves the burden on the upstream mill. Thus, the mill can crush more material with reduced specific energy requirements. At the same time, product quality is increased due to a more precise upper grain restriction.
