With a LAARMANN Ring Mill you put the sample together with a disc or a set of rings and roller in a bowl to bring it all together into 3-dimensional vibrations. Inside the bowls the sample will be ground and homogenized by high pressure, impact and friction rapidly down to analytical end fineness. Typically samples are ground to 90-95% <75μm in app. 3 minutes. Exact time and end fineness depends on the sample characteristics
