The ball mill's mechanical energy turns the plastic into a fine powder. The process also creates radicals — molecules with one or more unpaired outer electrons. "Radicals are very reactive," Yue says. In the mix, the radicals react with other molecules to convert crosslinked chemical bonds into the non-permanent types found in vitrimers.

It's easy enough to take your empty mill jar and add individual cups of water to it to determine its volume. Then divide that by 4 and that's the amount of, say, potassium nitrate to add to a mill jar run to finely pulverize it. You get the idea. The jar and barrel shown above both have a one-gallon volume which is 16 kitchen measuring cups.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
All work with explosive chemicals in open or closed systems must be done in a designated area of a laboratory inside of a properly functioning chemical fume hood. Emergency Irrigation.
