Heat sensitive materials very often will not work well in mechanical mills. Additionally, the friction generated by mechanical mills causes the devices to suffer from excessive wear, which reduces the effectiveness of the mill and increases the chance of product contamination. Lastly Mechanical mills tend to be difficult to clean.
Energy balance, constant pressure The energy balance for the constant-pressure case follows from Equation 6.15 CP dT dt . HRknA in which CP .VRˆCP is the total constant-pressure heat capacity. For an ideal gas, we know from thermodynamics that the two total heat capacities are simply related, CV .CP nR (6.21) 16/139
