Reducing energy consumption of a raw mill in cement industry

In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be 61.5% and 16.4%, respectively.Therefore, energy-efficient grinding technologies have become the main focus of the industry, especially in the cement industry with large-scale plants. Until now, various types of crushing equipment have been developed to meet the requirement of the industry, such as jaw crusher, cone crusher and vertical roller mill i.e., VRM [ 3,4,5 ].Minerals Free Full-Text Analysis and Optimization of Grinding

Review on energy conservation and emission reduction

In the cement industry, the total energy consumption accounts for 50–60% of the overall manufacturing cost, while thermal energy accounts for 20–25% (Wang et al., 2009; Singhi and Bhargava, 2010).The modern cement industry requires 110–120 kWh of electrical power to produce one ton of cement (Mejeoumov, 2007).Thermal energy is grinding stag e, producing raw meal, slag m eal or cement [2].

A critical review on energy use and savings in the cement industries

Grinding is a highly energy intensive process in the cement industry. Approximately 60–70% of the total electrical energy used in a cement plant is utilized for the grinding of raw materials, coal and clinker [63]. The electrical energy consumed in cement production is approximately 110 kWh/tonne.The results show that approximately 2.48t, 4.69t, and 3.41t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages(PDF) Analysis of material flow and consumption in cement production

Everything you need to know about Crushers in Cement industry

The roller crushers are used for moist and sticky materials. Generally the machines have to be rigid enough to crush also hard inclusions. As the reduction ratio is only about 5:1 a 2-stage crushing is required in most applications. Fast running type crushers like hammer and impact crushers are the simplest and cheapest solution, whenever theThus the cement industry is also facing climate change issues seen by the coal-fired electricity generation industry. However, the chemistry of cement clinker production has an added CO 2 element as well as that resulting from burning fossil fuels and that is the natural liberation of CO 2 from the raw materials used in clinker production.
