Due to their high separation efficiency and its high circulation factor, VRM tends to produce cement with a steep PSD curve unlike those generated by ball mills. Cement with a steep PSD is one with a high water demand. To address this issue, VRM manufacturers have come up with a more conventional raw mill VRM design. Investment Cost
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.

• Upgrade (in the case of an existing ball mill circuit) to combi-grinding with high-pressure grinding rolls (HPGR). In this case, the HPGR will be installed before the ball mill and replace the first ball mill chamber, increasing the length of the second chamber. Upsides are good energy efficiency and a high output increase.
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.
