Three silos are in place for clinker storage. As mentioned before the clinker kiln works on the dry procedure and meets the BAT requirements. Cement production 9 10 and 11 . The slag from the admixture hall is then stored in the cinder silos from the clinker mills. The cinder is dried with warm gasses from the grid cooler or when the clinker kiln does not operate by burning natural gasses in the drier s hotbed. Gypsum is transported from the admixture hall to the gypsum silos nearby the cement mills. The clinker cinder and gypsum contained in silos after a laboratory receipt are extracted dosed and supplied to the cement mills. The cement mills are tubular mills with balls having two rooms and operating in a closed loop. From the mill the material is brought to a high efficiency separator where it is separated the fine fraction cement being taken over in a haulage relay and stored in 9 cement silos the heavy fraction being recirculated into the mill. Cement shipping 12 from silos the cement can be supplied both as bulk material and in bags using rotary Mollers equipment. The cement delivery can be done by trucks or using the railway network. The basic product is cement 80 is clinker manufactured using a dry procedure which allows a production of 1 026 563 t year clinker. The technological flow may be synthesized into a scheme presented in Figure 2. The Deva Branch Casial has two technological lines to produce cement with millions tons a year capacity. The flow sheet of material balance from Deva Branch Casial is presented in Figure 3. Fig. 2. Flow chart of process fabrication Fig. 3. The flow sheet of material balance 384 Robotics and Automation in Construction Kiln operating Manufacturing cement by dry procedure is a huge energy consuming process. An important section of cement technological flow with a great share in finite product 80 is the making of the clinker .
