DetailretSCH Planetary Ball Mills are used for the pulverization of soft, fibrous, hard and brittle ma-terials. They achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can be as large as 10 mm. If the sample feed size is larger than this then the sample must first undergo preliminary size reduction.
DetailWhats unique about the MM 500 is that performance, handling, application fields and design make it a combination between a classic mixer mill and a planetary ball mill. When it comes to long-term grindings of several hours with high energy input to obtain particle sizes 1 m, Planetary Ball Mills have been the instruments of choice so far.
DetailIn our lab course, we will work with a centrifugal ball mill. The feedstock can be lled up to 10 mm and will be milled to particles of about 1 m. The mill consumes a maximum power of 100 W. Do not assume the mill produces 100W of comminution power In Fig. 6 the parts of the mill are described. A B C Figure 6 Centrifugal ball mill
