Energy-Efficient Technologies in Cement Grinding IntechOpen
1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC Review on vertical roller mill in cement industry & its

Cement Industry an overview ScienceDirect Topics
The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999 ). Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.2.4 Cement Industry. The U.S. cement industry consists of 39 companies that operate 118 cement plants in 38 states. While its production levels have grown since 1985, the industry's energy intensity declined by 35% between 1985 and 2000 (Figure 10 ). Sign in to download full-size image.
