Portland cement so widely used throughout the world. Methods of cement manufacturing 1 Wet process : grinding and mixing of the raw materials in the existence of water. 2 Dry process : grinding and mixing of the raw materials in their dry state. The process to be chosen, depend on the nature of the used raw materials. For
Optimum filling ratio. U= (volume of powder in the mill)/ (volume of voids in the charge): between 60% and. 110%, optimum around 90%. In practical terms, material level should equal ball level in the first compartment. In practical terms, material level should be higher than ball level in the second.
This fine powder is considered as cement. During grinding gypsum is also added to the mix in small percentage that controls the setting of cement. Phase VI: Packing and Shipping • Material is directly conveyed to the silos or large storage tanks of cement from the grinding mills. Further, it is packed to about 2040 kg bags.
Stage 6 clinker grinding (cement mill) A cement mill is the equipment used to grind the hard, nodular clinker from the kiln area into the fine grey powder that is cement. 1. Transfer of clinker to cement mill hopper from kiln silo: After the clincker is stored in the silo . To transport the clinker directly rejects silo is used to fill the lorry.
Control Room: Mill Control System Strategy, Operati on Data Trends. Nowadays most of the cement grinding systems are automatically operated from a. Centralized Control Room (CCR).
