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. The vane is additionally bent or curved over a major portion to ...
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Pulverizer spillage describes the condition when raw or partially pulverized coal passing over the edge of the bowl falls through the vane wheel or pulverizer throat to be rejected through the pyrite chute. No or miniscule amounts of coal should be discharged through the pyrite chute.
Dec 11, 2019· The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [,,,,, ]. The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber.
Any sundries inside the raw coal, like coal gangue, metal block, etc, will be discharged out of the mill by vane. The coal powder prepareation system is designed with safety measures, like anti-explosion value, inert gas fire extinguishing system, etc. Project Cases.
Mar 13, 1990· A rotating throat pulverizing mill has a soft steel vane wheel which rotates with the control bowl for classifying purposes. Wear-resistant vane liners slide onto the vanes to protect the upper surfaces thereof and are held in place, in part, by integral clips which underlie the vane plates and, in part, by wear-resistant cap plates which are welded to a flush upper flange of the vane wheel.
