Grinding jars and media for planetary ball milling can be obtained in a variety of different materials including stainless steel agate tungsten carbide and various ceramic materials. For wet grinding jars and media made from yttrium stabilized zirconium oxide ZrO2 will produce the best results with minimal sample contamination.
2. What is the capacity of milling we want The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume largest capacity on the market. Each grinding bowl can be filled 13 part of the volume 170 gr sample. So if we use two grinding bowls the optimum capacity is about 170 x 2 340 g per milling process.
Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1-1 centrifugal mode. The centrifugal forces pro-duced by the rotation movement the sample and the grinding balls against the inner wall of the grinding jar where size reduction takes place primarily by pressure and friction.

Nov 11 2013 Ball milling is a common method in the size reduction of material. The milling process produces nanopowders through the impact forces generated by action of centrifugal forces. Milling parameters such as milling time mass concentration and bead amount are important parameters that need to be considered in producing superfine powders.
