Graymont Superior Plant Upgrades (formerly CLM)
Superior, Wisconsin
Krech Ojard was retained initially by the Cutler Magner Corporation for services to be performed on their Duluth/Superior Harbor plant, which is now owned by Graymont, to provide professional services related to the construction of a new kiln #5, a state of the art high efficiency preheater lime kiln, and other upgrades at their large Superior, Wisconsin plant. The facility produces calcined lime products and ground limestone.
Krech Ojard was hired to design all of the refractory, process, and storage equipment, on pile and helical anchor deep foundations, to support the installation of the new kiln. Additional work focused on development of “Balance of Plant” process flow, conveyor systems, silo dust control, dust collector upgrades, crushing and screening operations, material re-claim tunnel, integrated rail and truck load-out systems, as well as significant structural modifications to existing buildings to support the new process equipment.
