Redesign reject valves, throat rings, classifier vanes, and other internal components as necessary for fuel and application. Perform mill dribble tests to determine minimum throat velocity & minimum PA flow. Perform mill response tests to evaluate proper balance of mill primary air/fuel ratio at high load.
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels .
The HPSC design incorporates the following features to achieve these improvements: Mill Top Extension – to increase the volume of the mill housing and allow for installation of the cyclone separator Pre-swirl Vanes – to control airflow in the upper mill housing, thus increasing the efficiency of the classifier blades Intermediate Deflector ...

Sep 28, 1999· An improved vane of the type adapted for use in the classifier cage of a bowl mill type coal pulverizer. The improved vane is designed such that its lower end extends below the classifier cage inlet when the vane is mounted in the inlet. In a preferred form, the vane has a generally trapezoidal shape with a longer lower edge.

dynamic classifiers, which went on line in April 1995, replaced the existing static centrifugal cone type classifiers in CE Raymond Mills. The new dynamic classifiers consist of five main components: the drive, fixed vane inlet louvers, rotating cage assembly, reject cone, and classifier discharge. Classifier .
An improved classifier cage for bowl mill type coal pulverizers which have been converted from stationary throats to rotating throats with reversed flow direction. The direction of the classifier vanes is reversed such that the rotational flow direction of coal/air from the rotating throat is generally maintained as it passes through the classifier cage into a classifier cone, rather than ...
