Substitute low-silicon shale for fly ash in cement production

As the resource shortage and price rising, Shandong Lubi Building Material Co.,Ltd. substituted low-silicon shale for fly ash in their cement production. And the problems in the production of using low-silicon-shale to burn clinker were stated as well as the the causes. Finally, low-cost stable production was realized by a series of measures as adjusting batching, kiln -furnace air matching and optimizing operation.
