Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by

Coal pulverizers and cement vertical roller mills operate in very similar ways. A table with large sized raw material rotates, while stationary grinding wheels roll over the material to grind it into finer particles. The wheel in these applications typically has a spherical roller bearing to take thrust loads and a cylindrical bearing to take

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

The main source of heat is coal burning. Coal is fired as a main fuel () in the rotary kiln and calciner chamber. Coal is burnt to provide the required heat for calcination and to convert the kiln feed into clinker. This red hot clinker further goes to clinker cooler for cooling the clinker from 1400 degrees to 200 degrees.

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.

If it should exceed 95 deg. C, the hot air damper must be closed. NOTE: Pulverizer startup will cause a sudden and sharp increase of steam pressure. This will level out rapidly as load is placed on the turbine. • Take the second coal mill in service in a similar manner when the coal feeding of the first mill has reached 90% of its maximum.
