Manufacturing process Lafarge
Step 1: Mining. The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loadedFrom hub-and-spoke model to split grinding; from single-grinding solution to a combination of system solutions; and from energy-intensive traditional ball mill to upgraded versions and use of pre-grinders, the cement industry is shifting towards more energy-efficient grinding solutions.

Cement is produced by a high-temperature (about 1500 °C) reaction in a rotary kiln of carefully proportioned and blended ratios of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3).The production of cement is a chemical process requiring an accurate blend of the previously cited four key organic oxides and the Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicateCement clinker

Satellite grinding units are cost-effective proposition
Today, India is self-sufficient in cement machinery manufacturing, especially grinding units except for very few castings, which are imported from Europe or Germany. Nevertheless, about 99 per cent of all the plant and machinery are being manufactured in India under the "Make in India" programme.Therefore, producing cement with less energy is becoming a key element of profitability: as the grinding process consumes about 60 per cent of the total plant electrical energy demand and about 20 per cent of cement production variable cost. So efficient grinding unit selection impacts profitability of cement manufacturing.Efficient grinding unit selection impacts profitability Indian Cement

How many cement plants are producing in India 2020?
210 Large Cement Plants in India 2020. A total of 210 large cement plants account for a combined installed capacity of 410 MT in the country, whereas, 350 mini cement plants make up for the rest. Of the total 210 large cement plants in India, 77 are in the states of Andhra Pradesh, Rajasthan, and Tamil Nadu.Considering cement manufacturing process, CO 2 emissions have been evaluated due to the use of electrical energy for (i) Initial grinding of raw materials (ii) mixing of raw materials in the silos before preheating (iii) final grinding of clinker with gypsum & other substitutes (e.g., flyash, slag, pozzolan etc.). 2.8.2.

grinding the cement clinker nodules to 100% passing 90 μm in a dry circuit. Grinding occurs at the beginning and the end of the cement making process. Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement. The electrical energy consumed in the cement making process is in order of Energy and raw material account for around 32% and 29%, respectively of the total production cost of cement in KSA. At the end of 2011, the cost of cement in KSA was US $64.6 per tonne, with Saudi cement manufacturers maintaining and enjoying gross profit margins above 50% compared to the GCC average of 30%.Trends and developments in green cement and concrete

Cement Grinding Cement Plant Optimization
Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.
