Abstract The kinetics of slowing down of breakage rates for fine wet grinding of 20×30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowing-down effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions.

The seeds must be too light or soft. I found the appropriate grind setting that didn't allow whole seeds to fall through, and wasn't so fine it turned to dust, but they were so oily from spinning around and around. It was taking way too long to grind 1 tablespoon of flaxseeds so I went back to hand grinding to finish the seeds.
