The speakers will discuss the c hemistry of clay activation for foundry applications\, the distribution of sand and its quality parameters\, and practical methods and control facto rs. The four-hour window will also include question and answer opportuniti es and breaks between presenters.\n\nLarry Kaiser graduated from Western M ichigan University with a Bachelor of Science in Engineering Metallurgy. W hile at Western Michigan University\, he was an FEF Scholar. Larry served as Chair of the AFS 4M (Green Sand Additives and Testing) Committee. He ha s over thirty-five years of experience in the foundry industry\, mainly wi th gray iron and green sand\, working as a Plant Metallurgist\, Melt Manag er\, and in Sand Systems. Larry is currently a Technical Manager for Ameri can Colloid Company/Minerals Technologies Inc. Larry Kaiser’s presentati on\, “Chemistry of Clay Activation\,” will describe the history and fo rmation of Bentonite\, and review the factors involved in the activation o f Bentonite for foundry applications. He’ll also explain the different c haracteristics of both sodium and calcium Bentonite. Finally\, Larry will discuss some practical considerations for best clay activation and green s and property development for the foundry.\n\nSara Joyce\, Strategic Leader of Product Innovation at Badger Mining Corporation (BMC)\, received a Bac helor of Science in Environmental Science at the University of Wisconsin-E au Claire. Sara began her career with BMC in 1984 as a lab technician at t he Fairwater Plant. In her 37-years at BMC she has held various positions including Statistical Process Control Team Leader and Quality Control Mana ger. Currently\, Sara coaches the foundry sales\, environmental\, quality\ , and engineering teams. Sara has received numerous foundry industry award s including an AFS Service Citation in 2004\, the Ezra Kotzin award in 201 2\, and has been a member of the Cope and Drag Club for many years.

Neil has been an active member of the AFS Twin Cities Chapter since 2011 and is ser ving on their board of directors. Sara and Neil will discuss working with your vendors on developing parameters and process controls for your sand g rades. By fine tuning the sieve distribution and catering to each foundrie s individual needs\, casting quality will improve\, and scrap will decline .\n\nAl Jacobson graduated from University of Wisconsin Platteville with a degree in Industrial Engineering. He has worked for Grede Foundries for 3 2 years\, and has held various roles in the foundry including Project Engi neer\, Mold/Core Superintendent. For the last 20 years he has been a Proce ss Engineer in charge of Sand Lab and Green Sand Control at Grede’s plan t in St. Cloud.\, MN. Al has been an active member of Twin Cities AFS Chap ter and most recently served as Chair in 2018-2019. Al’s presentation is entitled “Controlling a Green Sand System”. His presentation is\ngoin g to cover practical methods and philosophies that he uses to tightly cont rol 3 key variables in his 2 green sand systems at St. Cloud. The ideas th at Al is going to discuss can be applied to most any green sand systems wi thout large capital expense or demand for additional labor. He hopes to he lp generate ideas that can be applied in your sand systems to improve the stability of your process.\n\nRegister below (no cost) by Monday\, March 8 th at 12:00pm.
