Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.

Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, lowvolume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. Activation is analogous to making popcorn from ...

Most of the absorbed energy is dissipated to change the internal structure of the coal briquette. The more energy that is absorbed, the denser the final coal briquette formed. A high load pressure, long pressing time, and cyclic load can increase the energy absorption of coal powder to improve the density of the reconstituted coal briquette.
