Coal pulverizer

United States September 2018

Description

The coal pulverizer is applied to crush the coal to an average size of 0.074 mm powder. At the entrance of coal pulverizer, the temperature would be between 160 C to 393 C. The blowing speed is 50 to 55 m/second. When the high Cr cast steel (48-58 HRC) liner plate is used, the service life is 1.5 to 2 years, but spalling would be an issue. When the ceramic liner plate is used, the service life is extended, but the impact failure would be an issue. When the competitor’s CCO plate is used, the impact resistance is improved, but service life is only 1 year. Now the Duroxite 100 is being tested in the field. The service life data will be updated soon.
