Coil Pulverizers for Boilers
The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle …

slakers, or the ball mill media in a ball mill slaker. In the case of paste slakers, proper mixing is also needed to mitigate against the risk that localized hotspots (i.e., above boiling point) will develop in the slurry. The final factor to impact lime slaking is steam control. The slaking reaction
Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Understanding the mechanism: How does a ball mill work?
The working principle of a ball mill is based on the rotation of the drum, which causes the grinding media to fall onto the material to be ground. The force of impact breaks the material into smaller particles, while the friction between the balls and the material causes further grinding and refinement.
