Series A-758 Plus™ Paste-Type Lime Slaking System
The A-758 Plus™ Lime Slaker system provides reliable, efficient slaking of various grades of quicklime (CaO) at a substantial savings over other slaking methods. Our paste-type lime slaker produces a higher strength and more reactive paste resulting in more efficient use of lime. The resulting higher strength slurry reduces wasted lime and associated costs, ensuring treatment objectives are efficiently met. For over 40 years, we have pioneered the design and application of paste-type lime slakers. Our recent developments to the lime slaker technology bring new features which extend equipment life, reduce maintenance costs, and improve control and reliability.
KEY BENEFITS
• More reactive lime slurry improves efficiency, reduces lime costs and ensures treatment objectives are met
• More efficient; external heat souce not required
• Reliable performance and robust construction reduce operator attention and lower maintenance costs
• Faster slaking improves responsiveness, making it easier to control over a wider range
• Smaller footprint and flexible configuration make installation simple
FEATURES
Superior Paste-Slaking Process
Utilizing a low water-to-lime ratio (2:1), the A-758 Plus™ unit slakes lime as a paste which provides a number of benefits over the more traditional 4:1 or slurry slaking process. This includes lower power consumption, faster slaking, a smaller footprint and, most importantly, a more reactive lime slurry solution. In addition, the A-758™ Plus incorporates innovative controls to produce consistent and reliable paste concentrations.
Less Power
The 2:1 paste slaking process generates its own heat from the hydration heat of reaction. This avoids the need and expense of an external heat source, internal heat exchangers, and temperature control systems. Paste slaking combined with slow speed mixing conserves energy by 50% or more compared to other lime slaking systems.
Faster Slaking
Fast slaking is accomplished due to the low water content of the paste. Heat generated by the hydration completes the slaking process in approximately five minutes. This short retention time provides efficient start-stop or batching operation and the ability to make rapid changesin lime concentration when required. The simplified process also reduces maintenance costs.
Smaller Footprint
Faster slaking is more responsive to changes in demand, easier to control and offers a wider range of operation (20:1 turndown). Faster slaking also accounts for a compact size which saves on valuable floor space that offers installation flexibility.
More Reactive Lime Slurry
The intense heat generated by the 2:1 slaking ratio subjects the quicklime to thorough steam penetration. The resulting internal pressure promotes
the fracturing of the quicklime into smaller, more highly reactive particles. This means more surface area for more efficient lime usage to ensure treatment objectives are met confidently and with less waste.
Consistent and Reliable Slaking
The A-758 Plus™ incorporates automatic adjustment of the slaking water addition by measuring the torque on the paddle mixer shaft. The result is precise and continuous control of paste consistency without the need for operator intervention.
