  • Relationship between low cement grinding yield and equipment

    2. The relationship between circulating load rate and powder selection efficiency Powder selection efficiency is related to cycle load.For the same grinding system, the effect of cement grinding equipment increases with the increase of circulating load, and with the improvement of powder selection efficiency.And the efficiency of powder selection decreases with the increase of cycle load.

  • What's the Difference Between Cement and Concrete? CCAGC

    Portland cement's chemistry comes to life in the presence of water. Cement and water form a paste that surrounds and binds each particle of sand and stone. Through a chemical reaction of cement and water called hydration, the paste hardens and gains strength. The character of concrete is determined by the quality of the paste.
