Heat Integration in a Cement Production
1. Introduction. Nowadays, cement manufacturing is an energy-intensive industry. The energy costs of cement industry are about 40% of the product cost that indicates that this sector is one of the g = subtotal * ( (100-Hig)/100) Where C = Composition in % on loss free basis. Ca = CaO,Si = SiO2,Mg = Mgo,Al = Al2O3 and Fe = Fe2O3. subtracting Ash in clinker form g we get Amount of feed required to produce on kilogram of clinker.

Analysis of material flow and consumption in cement
The LN cement plant, located in the south-west of Shandong Province, was considered as a case study for the mass flow and balance analysis. This cement plant operates on a dry process line with a five-stage suspension pre-heater and an inline pre-calciner. The kiln is 4 m in diameter and 60 m in length.The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.Energy-Efficient Technologies in Cement Grinding IntechOpen

Energetic assessment of a precalcining rotary kiln in a cement plant
The process simulator was further conducted using reference plant data to identify an area of improvement of the cement rotary kiln plant's energy performance. The mass and energy balance of the rotary kiln process is shown in Table 3,which provides the data for both inlet and outlet streams of the rotary kiln network.Today, this aspect can not be ignored. A heat balance, simply stated, consists of compiling all the heat that is given to the kiln and then comparing this total to the total of thermal work done and heat losses that occur in EVERY THING YOU NEED TO KNOW ABOUT HEAT
