Lime Slaker

Plant requiring large quantities of lime slurry, could be cost-effective if the quick lime is slaked on site. The process consists of injecting quick lime in an agitated slaking tank maintaining high concentration. The exothermic reaction by mixing quick lime with water creates heat and steam.

A dust scrubber located on top of the tank removes this excess of steam and creates proper tank aeration. The process is automatically controlled and secured through temperature probe, electronic flowmeter and ultrasonic level probe. Once the quick lime is slaked, lime slurry overflows into a dilution tank in which water is added to obtain final concentration in order to be pumped.

Some processes are more simplistic and do not require a high-quality lime slurry. Batch slakers, also commonly referred to as mix tanks, produce a carefully metered slurry and are best suited to applications in which slurry production rate is relatively low and where there are few (if any) changes to the quicklime quality and water sources.

Batch type slakers are best suited for low usage applications that do not require a high quality lime slurry or where a downstream process requires a continuous flow of lime slurry. What’s more, they are best suited to instances with a consistent source of both quicklime and water. This means that they are often used in applications where a relatively consistent and small amount of hydrated lime slurry is required each day and where cost/supply prevents the use of hydrate or premade lime slurry solutions. Ultimately, for these types of applications, a batch slaker is the most economical and practical solution available in the market today.
