The Energy Balance for Chemical Reactors

We see by comparing Equations 6.22 and 6.23 that the numerator in the constant-volume case is larger because HR is negative and the positive RT is subtracted. We also see the denominator is smaller because CP is positive and the positive nR is subtracted. Therefore the time derivative of the temperature is larger for the constant-volume case.

a semi-autogenous (SAG) mill. AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process, where the second stage is carried out by the ball mill, but they can also be used as a one-stage grinder. The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills.
