Brand: Retsch | Category: Scientific & Laboratory Equipment

Two station planetary ball mill for grinding two samples in parallel under identical conditions, or one sample with a counterweight. Jar sizes go up to 125 ml and the mill reaches below 1 µm, and 0.1 µm for colloidal grinding. Input energy can be measured, which supports mechanochemical work.

Two station planetary ball mill taking jars up to 500 ml, with a higher sun wheel speed and a centrifugal acceleration of 64 g. The larger batch volume and higher energy input suit mechanochemistry and co-crystal screening as well as conventional fine grinding.
Single station planetary ball mill in which the jar rotates about its own axis on a counter rotating sun wheel, so grinding balls are driven across the jar wall by Coriolis forces. That produces high pulverisation energy and short grinding times, down to below 1 µm and to 0.1 µm for colloidal grinding.
Floor standing planetary ball mill with four grinding stations, taking a maximum batch of 4 x 220 ml, or eight samples with stacked jars. The speed ratio can be set to 1 to minus 2, 1 to minus 2.5 or 1 to minus 3, which changes the balance between impact and friction in the grinding action.
