The patented CLS Attritor Stirred Vertical Ball Mill Lime Slaker operates in continuous processing mode and has been used successfully in power generating plants for flue gas desulphurization (FGD). The Attritor will slake the lime as well as grind the inert grit, eliminating grit separation and disposal problems.

A method is shown for producing food grade hydrated lime. A source of raw, hydrated lime is first passed through a classification step which divides the raw hydrated lime into a first fine stream and a first coarse stream. The first coarse stream is then passed to a grinder which produces a ground coarse product. The first fine stream is separated out from the first coarse stream and, without ...

Lime slaking – In the next step, the quicklime is slaked by adding water. The volume of water added depends on the type of slaked lime specified. It is very important that the resulting hydrated lime is of uniform size and therefore, if necessary, the hydrated lime is crushed to the required size. ... limestone silo – a vertical limestone ...

A recent development on the lime slakers is the Generation 3 scrubber unit that can cope with the steam and dust created when unslaked lime is dispensed and mixed in the closed tank lime slaker. The scrubber has an integral fan that keeps the lime slaking tank under a light vacuum which prevents dust and steam from escaping through overflow ...
