If lime slaking efficiency is removed from the economic analysis, the higher cost and reagent consumption of hydrated lime still justifies the installation of a slaker.
Dry grinding has lower capital and operating costs but is restricted in the number of products that can be manufactured using this process due to its limited ability to reduce particle size. Wet grinding offers a number of benefits over dry grinding including greater flexibility in production options.
