Patented Classifier Cone Extension | Mill Modernization

he Flapper Valves on the MPS and MBF are designed to catch coal that has been rejected at the classifier level. The weight of the accumulated reject coal trips the Flapper Door and releases it for regrind. Air flow studies show that coal released from the Flapper Assembly falls into the air stream and can be carried back through the classifier to be rejected again, thus short circuiting

Application of CDF modelling to mill classifier design

Consequently, classifier design rules that have been derived from the extensive experience of milling bituminous coals are less reliable when applied to low quality coals. There is a clear requirement to improve and extend the range of applicability of classifier design methods so that they may be used to design classifiers of non-ideal

Pulverizer - Wikipedia

Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which consists of a stationary angled inlet vane assembly surrounding a rotating vane assembly or cage, is capable of producing micrometer -fine pulverized coal with a narrow particle size distribution.
