Effect of cryogenic grinding at varying temperatures (−30 to 10 °C and ambient), feed rates (5 to 7 kg/hr), and sieve size (0.8 to 1.5 mm) were evaluated with respect to mean particle size, grinding time, and volatile oil content. It was found that cryogenic grinding retained 62.56% more volatile oil as compared to ambient grinding.
