Enterprises urgently need to achieve green and sustainable development of the industry through technological innovation and product upgrading.
< IMG SRC = "https://img7.ccement.com/richtext/img/qpvn25cunwm1711623093715." He says cement requires a lot of energy to produce. The power consumption of cement grinding accounts for about one third of the total power consumption in cement production. At present, there are many grinding systems in the domestic cement industry, mainly including roller press combined grinding system, roller press semi-final grinding system and vertical mill final grinding system.
He compared the energy efficiency of various types of grinding systems and concluded that the vertical mill final grinding system was far below the first-level index limit of power consumption in the cement section, the roller press semi-final grinding system was slightly above the first-level index limit of power consumption in the cement section, and the roller press semi-final grinding system was slightly above the first-level index limit of power consumption in the cement section; The installed power of the vertical mill final grinding system is about 14 less than that of the roller press semi-final grinding system.
