Mechanical Disruption Methods: Beating

The key factor in dry grinding, especially seeds, is that the samples tend to be very hard and as such require a disproportionately large grinding ball. For instance, a grain of rice is only about 20 mg, and easily fits in a well of a deep well plate, but the 5/32” grinding balls used in that format have insufficient mass to crack the rice.
