A dozen Iola Rotarians were at Humboldt’s Monarch Cement Thursday for an up-close tour of the plant’s operations. During the tour, Monarch operations supervisor Dennis Osborn shows Monarch’s roller mill area. The group also visited the control center, where they’re shown how the different ingredients of cement, such as as limestone, bauxite, clinker and other materials are combined.
