摘要： Crushed flux lime to be used in a BOF converter is processed to minimize waste dust, obviate environmental complications caused by high pH in waste water, and to utilize a very high percentage of the original crushed lime for useful products. The crushed flux lime is screened to provide a fine grain fraction and a modified flux lime fraction. Only a small percentage of the modified flux lime fraction is dust which may be removed in a dust collection system, and the modified flux lime fraction is then passed to the BOF converter. The fine grain fraction is made into a highly fluidized lime of very small dimensions by pulverizing it further in the presence of a fluidizing agent.
