clay share in cement clinker production

clay share in cement clinker production Beaumont

New dry process cement production line process LCDRI CN. Aug 26, 2019 · Limestone is the main raw material for cement production. Each production ton of clinker requires about 1.3 tons of limestone, and more than 80% of the raw meal is limestone. 2. Clay raw materials. Clay raw materials mainly provide a small amount of cement clinker.
