A dynamic classifier has an inner rotating cage and outer stationary vanes which, acting in concert, provide centrifugal or impinging classification. Replacing or upgrading a pulverizer's classifier from static to dynamic improves grinding performance reducing the level of unburned carbon in the coal in the process.
