The pneumatic injection of quicklime and dolime in electric arc furnaces (EAF) is a well-proven improvement versus the practice of charging fluxes by conveyor belt systems and 5th hole roof opening. It improves refractory protection, continuous slag ing, viscosity control, distribution in the bath surface and overall process optimization.

Batch Slakers / Mix Tanks. 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 …
quicklime (particle size up to ¾") and produces slurry with up to 30% solids. This solids concentration allows any lime added to the slaker to be quickly mixed eliminating hot spots from forming. Our detention slaker produces a highly reactive lime slurry to meet your application needs and maximizes your lime usage. WHY USE THE ZMI PORTEC LIME
Additionally, when using quicklime, hotter slaking temperatures can reduce the total time required to complete the slaking reaction as illustrated in Figure 1.
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 …
Quicklime, also known as calcium oxide (CaO) or simply lime, is produced by heating limestone or calcium carbonate in big furnaces. During this heating process, CO2 is released from the stone, resulting in the formation of CaO along with some other small mineral components. This CaO byproduct is what's commonly recognised as high calcium ...
Without any physical changes, the RDP Tekkem Slaker can switch over and become an accurate hydrated lime feed system allowing the use of either calcium oxide (quicklime) or calcium …
