    Dynamic Classifiers Improve Pulverizer Performance And

    By adding a dynamic classifier to the pulverizers you can better control coal particle sizing and fineness and increase pulverizer capacity to boot. 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 pulverizers classifier from static to dynamic improves grinding performance reducing .
