  • Slurry Stream Sample Cutter Dimensions for Grinding ...

    A good grinding circuit survey (and flotation circuit sampling) is only as good as the sample cutter used for each slurry stream. Correct sampler volume and opening size insures your sample is representative of the concentrator stream you are testing. Here is a good suggested design with opening dimensions. You need to add the handle that matches your sample point location.

  • Grinding of leaves for extraction of nucleic acids

    The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. 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.
