The Planetary Ball Mill PM 200 is a powerful benchtop model with 2 grinding stations for grinding jars with a nominal volume of 12 ml to 125 ml. The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short grinding times. The PM 200 can be found in virtually all industries where the ...
