Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery. Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding to analytical fineness.
Impact breakage may occur as a result of a particle being smashed between balls or between a ball and the mill lining, but is also generally defined to include slow compression fracturing, or crushing of particles between grinding media.
extremely fine since production of nanoparticles is possible with wet grinding. Pigments for inks and paints might be ground in the medium in which they are to be suspended. Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher.
