DESIGN & CUSTOMIZATION
Yargus Manufacturing, based out of Marshall, IL, designed, manufactured, and installed the 250 TPH receiving system for Key Cooperative in Grinnell, IA. This was a unique system regarding the receiving and load out area are the same. The greenfield facility constructed by Marcus Construction was designed to contain 22,000 tons of fertilizer. The truck receiving system is dual lane operation consisting of a 250 tons per hour stainless steel constructed chain paddle. Material moves via the chain paddle from the conditioning pits, up through the bucket elevator legs.
From there material can be dispensed into the tower bins or via the shuttle conveyor into the storage building. The blend tower contains twin 16-ton weigh hoppers which are capable of feeding into either 16-ton tapered vertical blender. The blend tower also contains interior stainless stairs increasing the towers safety, longevity and ease of maintenance.
