LIME SLAKING SYSTEMS
Chemco's Lime Slaking System utilizes pebble lime's higher neutralization capacity based on tonnage to provide storage, dry feed, slaking of pebble lime, and the delivery of the resultant hydrated lime slurry to the process point. This system employs Chemo's proven temperature control operating philosophy to deliver consistent, high quality hydrated lime without the need for maintenance-reliant weighing devices. Temperature control of the slaking process has proven, over our 40 years of industry experience, to be the most reliable method of ensuring consistent, small hydrated lime particle size, which greatly increases system efficiency and reduces operational and material costs. Our team will work closely with the design engineer and customer to determine which lime slaker best accommodates their application and to provide a reliable system that is engineered for functionality and operability.
An inherent component of handling & slaking pebble lime is the necessity to remove the inert grit material from the lime slurry that is a by-product of the lime slaking process. Chemco's grit separation stage is engineered to separate and remove grit from the lime slurry before it is pumped to process. The grit separation stage prior to pumping eliminates excessive grit loop pumps and associated hardware, which significantly reduces capital costs. This practice also eliminates the wear and tear that occurs from recycling grit through the primary feed lines and pumps, further cutting down on maintenance and equipment replacement costs over time.
The specific grit separation process to be used on a system is determined by our engineering team when finalizing the design with the customer to meet their operational needs and project specifications. The grit removal system can be incorporated into the lime slaker body so that it functions seamlessly as a single unit or can be located separately based on silo space limitations.
Lime is used in both municipal and industrial processes to improve water quality, by either controlling pH, removing impurities, or softening water. In systems that demand large quantities of lime, quicklime is ideal as the density is twice the density of hydrated lime, which reduces the storage and transportation costs.
