Lime Slaking Systems
STT knows that no two lime and water combinations are the same, and how these are slaked will have a major impact on the quality of the produced slurry. We can help you select the correct equipment to minimize your lime consumption, material cost and operating cost of your lime slaking system.
The first step toward highly effective slaked lime is selecting the right type of slaker based on your specific parameters.
We design and provide a variety of slaker types, but first collaborates with you to determine the best option for your process and budget.
STT takes the time to understand your application, process and site specifics, ensuring you get the type of slaker optimized for your needs.
Detention slakers are relatively inexpensive to install and are well suited to applications where lime quality is reliable. STT has taken one of the best detention slakers on the market, the ZMI Portec®, and made it better with operational upgrades.
Research has shown that for any given quicklime source, slaking temperature control is the single most important factor influencing the reactivity of the final lime slurry. Our fully automated temperature control provides a highly reactive slurry and minimizes hot spots.
- Fully automated operation
- Horizontal paddle ensures complete reaction of lime and water
- Wetting bowl inlet eliminates lime feed plugging
- Consistent and completely mixed slurry, with no hot spots
- Effective dust and steam removal from forced draft wet scrubber for a clean, safe and operator-friendly environment
- Mixer breaks the water surface eliminating risk of violent reaction or explosion
- Vibrating screen for effective grit removal
Some processes are more simplistic and do not require a high quality slurry. Mixtank/Batch type slakers produce a carefully metered slurry, and are best suited to applications with relatively low slaking rate along with consistent quicklime and water sources.
Most cost effective solution to meet slaking needs
Low maintenance cost due to simplistic operation
Available in a wide range of slaking capacities, up to 500 kg/hr.
STT can customize mix tanks with various options to meet your needs. Let STT review your requirements to determine the best fit for your application.
Vertical Ball Mills
When lime or water quality is poor and/or when lime consumption rates are high, STT designs slaking systems utilizing a vertical ball mill. The total grinding process of a vertical ball mill utilizes all residual reaction value, virtually eliminates grit disposal problems, and significantly improves lime usage efficiency.
STT has partnered with Metso to integrate the VERTIMILL® into STT’s complete system package. This, along with our patented lime feed arrangement specifically designed for the Metso Vertimill, ensures all lime fed to the mill reacts completely with water to produce a highly reactive slurry.
Minimizes effects of poor lime or water quality, giving end-user more options for sourcing
Improved lime slaking efficiency with our patented lime feed design, reducing feed costs
Produces ultra-fine, highly reactive product, increasing operational efficiency
No grit removal required, reducing waste fees
Minimal maintenance cost
When your environment is demanding or requires grit to be ground and retained in the lime slurry, rather than being screened, collected, and disposed of, STT has the experience to overcome your obstacles and design the right product to achieve your operational goals.
