There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.
The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.
Dynamic classifier manufacturer for coal mill Dynamic classifiers a fine way to help achieve lower Apr 08 2004 The behaviour of the mill under these conditions was benign and the condition could be easily corrected by either reducing the speed of the raw coal feeder andor the speed of the dynamic classifier rotor email protected .
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 ...
The DSVS® rotating classifier provides a means to increase coal fineness and/or throughput (Figure 2). This mill retrofit goes well beyond the improvements achievable with stationary classifier retrofits, especially when 80+%/200 fineness is required. Rotating classifier pressure drop is lower than that of stationary classifiers.

Classification performance of model coal mill classifiers . The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [5-10]. The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill .
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
