1. Introduction. The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [,,, ].The first generation of the coal mill classifier used static guide vanes to produce a ...
classifier, which consists of a cone equipped with adjustable vanes, is an option at a lower cost since it contains no moving parts. With adequate mill grinding capacity, the MPS mill equipped with SLK static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or
A better understanding of classifiers typically used in conjunction with coal grinding circuits would result in the ability to better utilize energies expended in coal grinding. In addition, the ability to better control the product size distribution is of major importance to many new processes being introduced to our energy conscious economy.
