Although about l.SSt raw materials are required to produce 1t of clinker,kiln feed-to-clinker ratio is typically 1.65-1.75 as weighed, due to the loss of dust with exhaust gas, later collected and returned. The ratio should be periodically reconciled with clinker and cement inventories and with measured dust loss in the preheater exhaust.
