The AFS Twin Cities Chapter presents a virtual “Green Sand Seminar” on March 9th from 12:00 p.m. – 4:00 p.m. Presenters for the seminar are Larry Kaiser from American Colloid Company/Minerals Technologies Inc.; Sara Joyce and Neil Kniseley, Badger Mining Corporation; and Al Jacobson, Grede – St. Cloud. The speakers will discuss the chemistry of clay activation for foundry applications, the distribution of sand and its quality parameters, and practical methods and control factors. The four-hour window will also include question and answer opportunities and breaks between presenters.

Larry Kaiser graduated from Western Michigan University with a Bachelor of Science in Engineering Metallurgy. While at Western Michigan University, he was an FEF Scholar. Larry served as Chair of the AFS 4M (Green Sand Additives and Testing) Committee. He has over thirty-five years of experience in the foundry industry, mainly with gray iron and green sand, working as a Plant Metallurgist, Melt Manager, and in Sand Systems. Larry is currently a Technical Manager for American Colloid Company/Minerals Technologies Inc. Larry Kaiser’s presentation, “Chemistry of Clay Activation,” will describe the history and formation of Bentonite, and review the factors involved in the activation of Bentonite for foundry applications. He’ll also explain the different characteristics of both sodium and calcium Bentonite. Finally, Larry will discuss some practical considerations for best clay activation and green sand property development for the foundry.

Sara Joyce, Strategic Leader of Product Innovation at Badger Mining Corporation (BMC), received a Bachelor of Science in Environmental Science at the University of Wisconsin-Eau Claire. Sara began her career with BMC in 1984 as a lab technician at the Fairwater Plant. In her 37-years at BMC she has held various positions including Statistical Process Control Team Leader and Quality Control Manager. Currently, Sara coaches the foundry sales, environmental, quality, and engineering teams. Sara has received numerous foundry industry awards including an AFS Service Citation in 2004, the Ezra Kotzin award in 2012, and has been a member of the Cope and Drag Club for many years. In 2017, Sara was the first woman to receive an AFS Gold Medal for service to the industry.

Neil Kniseley, Sand Sales for Badger Mining Corporation graduated from Winona State University with a degree in Business Administration. Neil started working at Badger Mining in 2009 as a sand plant operator and joined their sales and business development team in 2011. Neil has been an active member of the AFS Twin Cities Chapter since 2011 and is serving on their board of directors. Sara and Neil will discuss working with your vendors on developing parameters and process controls for your sand grades. By fine tuning the sieve distribution and catering to each foundries individual needs, casting quality will improve, and scrap will decline.

Al Jacobson graduated from University of Wisconsin Platteville with a degree in Industrial Engineering. He has worked for Grede Foundries for 32 years, and has held various roles in the foundry including Project Engineer, Mold/Core Superintendent. For the last 20 years he has been a Process Engineer in charge of Sand Lab and Green Sand Control at Grede’s plant in St. Cloud., MN. Al has been an active member of Twin Cities AFS Chapter and most recently served as Chair in 2018-2019. Al’s presentation is entitled “Controlling a Green Sand System”. His presentation is
going to cover practical methods and philosophies that he uses to tightly control 3 key variables in his 2 green sand systems at St. Cloud. The ideas that Al is going to discuss can be applied to most any green sand systems without large capital expense or demand for additional labor. He hopes to help generate ideas that can be applied in your sand systems to improve the stability of your process.
