9 MANUFACTURING PROCESS Raw Material Availability: Clinker received through Railway Wagons from Mother Plant located at Devapur (Telangana). Gypsum received through Trucks from Various Dye & Chemical industries located in Gujarat State. Fly Ash received through Bulkers from Bhusawal Thermal Power Station, Deepnagar, Bhusawal (MS). Storage: Clinker, Fly Ash and final product Cement stored in respective Silos and Gypsum stored in Covered Shed. Manufacturing Process: Raw Material Feeding requirements. - Feeding of material through Weigh Feeder/ SFM as per production Pre grinding: - Feeding material to Roller Press for pre grinding. Finish Grinding - Transfer of material to close Clinker Ball Mill through a discharge chute. From the mill material transferred to through air to Separators. Storage of product in Silo & Packing - The final material storage to Cement Silo, which is connected to the Packing Machine for automatic filling of OPC & PPC cement into the bags. Loading & Transfer to Destination Point- Finished product is loaded into load carriers and taken to the required destination as per dispatch need. 8

10 ENERGY CONSUMPTION Overall Power Consumption Energy Consumption (kwh/t of Cement) Reason for variation: High Sp. power consumption in due to following reasons 1. Frequent Start - stop due to low market demand. 2. Higher percentage of OPC Production. 3. Lower grindability of clinker due to usage of pet coke in clinker manufacturing on trial basis. 9

19 Partial diversion of CM-2 coarse material to CM-1 Mill Theme: Productivity improvement through diversion CM-2 coarse material to CM-1 Mill Background: Line 1 commissioned in 2000 and retro fit mill circuit and detailed study has been done and concluded that CM-1 ball mill having excess capacity to take further material. Simultaneously studied CM-2 circuit and noticed that Roller Press Separator having excess capacity. 18

20 Description of Modification: Airl side along with weighing system installed and also feed bucket elevator capacity enhanced. Benefits: 1. Mill production rate increased by 15 TPH. 2. Sp. Power consumption has reduced by 1.5 kwh/mt of Cement. 3. Smooth operation. Savings: Investment made : Rs. 52 Lacs Payback : 4.24 months 19

21 Implemented in FY Theme: Pneumatic Fly ash unloading system replaced with partially pneumatic - partially mechanical system. Fly ash unloading with conventional pneumatic systems to silos at 40 mtrs. Solution: Provided intermediate 50 Mt bin with lower height (i.e. 10 mtr) Due to lower height of bin, blower air is sufficient to convey material in place of costly Compressed air. Bin to Silo material conveying by existing bucket elevator. 20
