STT's expertise in lime slaking is unmatched in the industry. With their help we've decreased our quicklime consumption by nearly 10% annually and decreased our maintenance costs. Their System Optimization Study (SOS) is the most cost effective approach to reducing your quicklime consumption and slaker maintenance costs. They are the only name we trust when it comes to understanding lime slaking - and you should too.

The VERTIMILL® lime slaker system was originally designed for 30 tonnes per hour but was only able to run smoothly at 65% of design capacity. Even at reduced capacity, monthly cleanout of the downstream equipment and piping was required, resulting in lost production and increased operating costs.
When the system was commissioned there were several factors that were limiting the system's ability to run at design throughput.
STT Enviro Corp took a systematic approach to understanding the capacity limiting issues and developing a solution. First, one of STT's Slaking Specialists completed a Scientific Study on-site to identify the factors affecting performance. The Study concluded that there were six factors contributing to performance issues at the plant:
BEFORE: VERTIMILL® slaker without STT's modified feed arrangement. The absence of the modified feed arrangement allowed unreacted lime to leave the slaker without proper slaking and grinding.
AFTER: The modified feed arrangement (shown in blue) ensures that hydraulic short circuiting is eliminated. All quicklime fed to the slaker is forced below the slurry liquid level for complete slaking and grinding thus resulting in increased throughput and significantly improved lime slurry quality.
We are so confident in our methodology that if we can't find ways to save you at least 8% of your current quicklime consumption, you won't pay for our study. Don't wait. Call us today.
