FEATURE 86 • ROCK products • August 2019 www.rockproducts.com The Finish Mill Circuit In a Cement Plant Can Be Optimized by Using an Online PSD Analyzer Jeff DeNigris, Sensors & Automation – Product Manager, NAM, Malvern Panalytical The finish mill circuit in a cement plant can be optimized by using an online PSD analyzer. Knowing the real-time PSD from the mill can provide the means to reduce over grinding and the heavy cost of energy it causes. When the fines frac- tion (%<32um) increases above set limits, costly overgrind- ing is beginning to impact energy consumption and may also cause curing problems through rapid hydration. Likewise, an increase of the course fraction may cause incomplete hydra- tion and early strength results may suffer. This talk will give an overview and practical examples of how an integrated on-line analysis of PSD at the finish mill can provide real time data to improve process performance and efficiency.

Thursday, Nov. 21, 2019 Special Tour of Argos USA's Atlanta Grinding Facility Located in the heart of Atlanta, along the Chattahoochee River, the Argos Atlanta Cement Plant was built in 1962 with its first production following in 1963 with one kiln and one mill. After five years, a second kiln and mill were added and would produce for the Atlanta plant for the next 38 years. In 2006, kiln operations ceased as a result of environ- mental emissions. Despite no longer producing clinker, the Atlanta cement plant is a unique asset within the Argos U.S. operations, since it hosts the company's color lab and color blending operation, as well as its grinding capabilities. In addition, the plant has the logistical capability to receive materials and ship to Argos' customers by rail or truck. The plant employs 40 active, non-union employees with an average of more than 22 years of service who are highly dedicated to supporting Argos' values of safety, community engagement and environmental responsibility.
