a mill product tank. The mill product pump transfers the slurry from the mill product tank to the classifiers. The classifiers separate the limestone slurry based on particle size. When properly set up and operating, the fine material flows from the classifier overflow to a limestone storage tank where it is stored until needed by the FGD system.

Lime Slaking Mill - Metallurgist & Mineral Processing Engineer

A horizontal ball mill can be used as in a lime slaking circuit just as well as a vertimill. Some operations apply the raw quicklime directly to the ore on the belt moving toward further crushing or grinding. In this application, it is necessary only to have a suitable lime storage tank with a live bin bottom and a means for metering the lime from the tank to the ore. Such metering devices may ...

limestone slurry preparation system

Limestone scrubbing is the method of choice for coal-fired plants, yielding efficiencies of 90% - 98%. SO2 is neutralized by direct contact with limestone slurry in an absorption tower. Slurry is produced by crushing limestone in a ball mill and mixing it with water. During this slaking process, conversion to calcium hydroxide is achieved.
