Calculation of the power draw of dry multicompartment ball mills 223 Where gross power is the power input to the motor, noload power is the power input to the motor when the mill is empty, chargemotion power is the power associated with the movement of the charge, and (k x chargemotion power) is the

Effects of temperature on hydration. The rate of hydration of the cement phases, however, will increase with increasing temperature, and the resulting thickening and setting times will decrease. Above 230°F (110°C), the hydration products formed differ considerably from those obtained at lower temperatures.
