Tests at the NEA's pilot plant with various materials have shown that the radial classifier mounted on airswept impact and roller mills can achieve throughput increases of 30 - 160 % versus static classifiers and 10 - 50 % versus dynamic axial classifiers. Meanwhile, more than 30 retrofits were successfully done.
The NEA Radial Classifier has a compact design, simple construction and an easy access to all inner parts. Maintenance costs are reduced to a minimum.
A quick and accurate control of the fineness and product quality can be adjustetd by the variable speed rotor drive.
This is an important advantage, especially in case of frequent product changes with different quality specifications.
