Rod mills, how they function

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

Grinding of leaves for extraction of nucleic acids

The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low. Preventing sample warming can be done be adding additional liquid nitrogen to the mortar while pulverizing the sample. Low throughput is a more difficult issue as a mortar can only be used once before it must be cleaned.
