Berry Metal Company has successfully commissioned a newly developed, state-of-the-art lime injection system at Big River Steel. The scope of the project included the design and supply of a comprehensive technology package for pneumatic lime injection at BRS's greenfield facility in Osceola in Arizona. The system, which was installed as part of the BRS Phase I EAF, was successfully commissioned in May of 2020. Berry has also been contracted to install a similar system when BRS completes its Phase II EAF in 2021. The custom designed system hit the targeted flow rate of 1,000 lbs per minute for Dolomitic and HiCal, which is one of the highest flow rates in North America.

This new lime injection technology provides two critical advantages. First, it allows for successful flow of various gradients and sizing of lime particles from lime dust up to 1 Vi nominal sizing without clogging. Second, the Lime Injectors provide an accelerated punch into the bath increasing yield and efficiency in the steel making process.

The system, which includes all components from the outside transporter to the injector, was installed and cold commissioned while the mill was running so that no normal operations were reduced. All calibrations and test testing was performed on scheduled downtime.

Berry formed an exclusive partnership with Nol-Tec Systems to incorporate their patented Air Assist Injection and Transport Technology, enhancing Berry's complete Lime Injection System from silo into the furnace via Berry's patented Lime Injectors/Burners. The system is completely self-contained and sealed, reducing lime consumption and yield losses that typically occur in transport, delivery and at injection points. By preventing lime dust from entering the work environment, plant cleanliness is also improved.
