The show the flow diagram of the dry process of the manufacture of cement. 1. Dry Process. In the dry and semidry process the raw materials are crushed in a dry state. Then they are processed in grinding mill dried and reduced to very fine powderlike. That dry power is further blended corrected for the right composition and mixed
Inside at 1400 degrees C the raw material is transformed into clinker small dark gray nodules 34 centimeters in diameter. 9. Cement milling The clinker is ground by differentsize steel balls while it works its way through the mill s two chambers with gypsum being added to extend cement setting times. 10. Cement packaging and shipping
Crushing of cement raw materials is a process to cut large particles into a smaller sizes. The raw material of cement usually include limestone clay shale tripoli and others limestone is always the main composition for reducing g the transportation cost most cement plant would be located near the limestone quarry.
Various stages of dry process of manufacturing cement are described below 1. Crushing Storage The limestone and clay are ground separately to a size of about 25 mm in crushers. Then it is pulverized into fine powder in ball mills and tube mills. The crushing and pulverizing process is carried out separately for each material.
This is done by a mixture of both aircooling and watercooling including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding gypsum can be partly dehydrated forming hemihydrate or plaster of Paris 2CaSO 2 O.
