Bulk Lime Slaker Tank Manufacturing Our slaking/mixing tanks have a 23,000 gal. capacity and can process a pneumatic tanker of quick lime in about an hour, producing a hydrated lime slurry. Tanks can be portable or skid mounted and either electric or diesel powered.
Hydrated lime (Calcium Hydroxide) can be prepared using labor intensive 80# bags or an automated system using super sacks or some other method of dry feeding the hydrated lime. As for the mixer design, the use of an upper impeller is definitely recommended when considered for storage of hydrated lime.

A suspension of calcium hydroxide in water is hydrated lime slurry. The manufacturer adds approximately 20% water to calcium oxide to produce hydrated lime slurry. There is a difference between the raw materials that produce calcium hydroxide or hydrated lime slurry .
The hydrated lime is stored in two storage silos equipped with external vibrator unloaders, and an obsolete feeding and slurry system. Problems Unloading and Feeding the Hydrated Lime The hydrated lime system was composed of two independent storage silos, both equipped with external vibrator unloaders.
Hydrated Lime Systems Lime feed equipment for neutralization and pH control. Lime feed equipment can be a water treatment operators worst enemy or best friend. For decades dry lime feed systems have been designed with a dry storage silo and a lime slurry mix tank at its base.
Mixing hydrated lime and water in a lime dissolution tank. The lime is stored in a silo and metered into the mixing tank via a bulk material discharge system while water is added. The high potential for metering and concentration is ensured by suitable measurement systems.
BROMATCO co-developed a revolutionary process for manufacturing hydrated lime slurry from quicklime for use in a variety of industries and municipal water and wastewater systems for treating water, in the pollution control industry for treating acid mine waste. The process (patent pending), called Lime-Save, results in a hydrated lime slurry .
Aug 01, 2017· Hydrated lime, also known as calcium hydroxide lime (Ca(OH)², is available in white powder form and can be mixed directly in solution tanks and employed in dry form. Hydrated lime is commonly used as a primary coagulant for the treatment of industrial waste streams and contributes to the clarification of water.
