Coal utilisation in the cement and concrete industries ...
· The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
UNIT 1 HARDGROVE GRINDABILITY INDEX
The Hardgrove Grindability Index was developed as an empirical test to indie how difficult it would be to grind a specific coal to the particle size necessary for effective combustion in a pulverized coal fired boiler. Its use has been extended to cover the preparation of pulverized coal for the cement, steel and chemical production industries.
