Correctly sized coal particles pass through the classifier and exit the mill through the discharge duct. Pulverized coal that has passed through the classifier is pneumatically conveyed to the furnace. Coal Pulverizer Types (Impact, Crush and Attrition) The type of pulverizer employed depends upon requirements.

Abstract: 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 initial rotational direction of the coal/air flow around the pulverizer is imparted by a number of angled throat vanes in the throat, and subsequently modified by the classifier vanes to flow...

A pulverizer hammer mill is a mechanical grinding device that is used for parting distinct types of materials. Coal and mining industry uses this device to pulverize coal for combustion in steam-generating furnaces for fossil fuel power plants. Major types of pulverizer design available in the market are- Low speed pulverizer Medium speed pulverizer High…

As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.

Most existing pulverizers—both the vertical-shaft and ball-mill types—come with a static classifier. Its blades reject coarse particles to …

Dynamic classifiers allow instant adjustment to provide wide flexibility of operation and size specifications. The vertical blade classifier (VBC) is the Bradley standard classifier for efficient classification of fine ground powders. The BLVT reduces the recirculating load in the mill system which results in higher throughput and less wear.

For use in a classifier cage of the type used in bowl mill coal pulverizers to direct a flow of coal fines and air into a classifier cone, the classifier cage having a circumferential inlet for receiving a flow of coal fines from a pulverizer throat, an improved classifier vane comprising:

Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
