Apr 08, 2004 COAL PLANT UPGRADE AND RETROFIT. Dynamic classifiers: a fine way to help achieve lower emissions ... A better solution is to exchange the static classifier for a dynamic (or "rotary") type. And the latest generation of dynamic classifiers is indeed proving to be a good way of improving the fineness of the ground coal leaving the mill, with the ...
Read MoreThe SAS Adjustable High Spin Static Classifier Retrofit is a proven and reasonable alternative to making the substantial capital commitment required for Dynamic Classifiers. SAS customers have achieved 6% to 15% capacity improvements, while concurrently reaching 99.8% thru 50 mesh and 76.2% thru 200 mesh fineness levels – grinding at 42 HGI coal.

Read MoreA dynamic classifier for a coal pulverizer has an improved drive mechanism which is mounted on top of a pulverizer and concentric with the classifier axis of rotation and is directly controllable. The drive mechanism is a variable-speed DC or AC electric motor having a hollow motor shaft. The motor can produce classifier rotor rotational speeds of between 50 and 200 rpm.
Read MoreApr 07, 2004 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.

Read MoreThe 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.
