cement particle an overview sciencedirect topics

The zeta-potentials ofcement particlesin aqueous solution with different dosages of superplasticizers are shown in Figure 7.11.The results indicate that SCS can makecement particleswith similar negative zeta-potential as PCs. The minimum zeta-potential appeared at an SCS dosage of 0.35%, and the dosage is consistent with the optimal dosage of fluidity and …

thecement mill understandingcement

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different size grinding media
