A high reactive soft-burned lime will produce 490 BTUs of heat per pound of quicklime. A low reactive lime will produce about 380 BTUs per pound of quicklime. These BTUs will bring the slurry temperature to a certain degree based on temperature of the dry lime, temperature of incoming water, and heat losses from the slaker vessel.

Slaking occurs when quicklime is reacted with water to form Ca (OH) 2, most commonly called hydrated lime in its dry form or lime slurry or milk of lime in its wet form. The slaking process is exothermic, releasing heat as the quicklime and water mix and chemically combine. A lime slaking system that is not running at its peak could be unsafe ...

Prater Mega Mills . Prater's Mega Mill is essentially a hammermill that works to crush particles through impact, acting as a secondary piece of reduction equipment.
