  • Vertical-axis wind turbines: what makes them better ...

    When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation. Simply put, because power generation efficiency isn't as good, VAWTs aren't as good long-term investments. This is ultimately why wind-energy developers have stuck with the HAWT ...

  • Raw Mill In Cement Plant,Cement Making Plant

    This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill. The grinding process is controlled to obtain ...
