  • cement mill dynamics in rotor speed

    cement mill dynamics in rotor speed The separator's rotor speed (or motor power) and air flow rate are crucial parameters for controlling cement fineness and residue [10, 11, 25, 26]. Hence, increasing the rotor speed will elevate the product's fineness and increase the rejects (B2), since more particles will be returned back to mill.
