Lime Slaking Equipment Mineral Processing & Metallurgy

A lime slaking and addition system can consists of two systems to control the pH in the rougher and cleaner flotation circuits.A pebble lime silo will dose dry lime to the SAG mill feed belt a hydrated lime make down system will provide slurry lime to multiple addition points in the flotation circuit. Other lime delivery options are detention slakers and Vertimill slakers.

What is Quicklime and How is it Made? ScienceStruck

But the most common treatment is slaking, or addition of water to the quicklime. This is an exothermic reaction, which means it results in the evolution of a large quantity of heat to form calcium hydroxide or slaked lime. The process of hydration is carried out in a continuous hydrator, after which micronsized slaked lime particles are produced.
