A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned.
The Coal Pulverizer plant was commissioned on 30thNov. 2016 and is running efficiently till date. Produces 60-70% 200 mesh coal fines and the hammer life has been beyond compare at three months for a single set of 6 pcs. The workmanship is of the highest order, zero leakage of coal ; indeed energy efficient machine! AAR KAY Industries
Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.
