PLANETARY BALL MILLS THE CLASSIC TOOLS FOR PULVERIZATION TASKS PLANETARY BALL MILLS
RETSCH Planetary Ball Mills are used wherever highest demands are placed on speed, fi neness, purity, and reproducibility. They pulverize and mix soft, medium-hard to extremely hard, brittle and fi brous materials and easily achieve fi nal fi nenesses down to the lower micron range. For wet grinding, even grind sizes in the nanometer range are possible. In addition to classic grinding tasks, the mills also meet all requirements for colloidal grinding and have the necessary energy input for mechanical alloying.
Powerful and fast grinding down to the submicron range
Reproducible results due to energy and speed control
Suitable for long-term trials and continuous use
Allows for both dry and wet grinding
Wide choice of materials for neutral-to-analysis grinding

etary ball mills. The PM 100, PM 100 CM and PM 200 are benchtop mod- els with one or two grinding sta- tions. The PM 100 CM operates in centrifugal mode, i.e. the speed ratio of the sun wheel to the grinding jar is 1: -1. This leads to a more gentle size reduction process with less abrasion. The PM 400 is a fl oor model with two or four grinding stations, which permits to grind up to eight samples simultaneously by stacking the grinding jars. To generate the high energy in which is required for mechanical all y- ing, the PM 400 is available as “MA” version with a speed ratio of 1: -2.5 o 1:-3.

The “comfort” range of grinding jar has been specially designed for extreme working conditions such as long-te trials, wet grinding, high mechaniic loads, maximum speeds as well as fors for mechanical alloying. A wide range materials and sizes (12 ml - 500 m also for the grinding balls, allows a largely neutral-to-analysis preparationion adapted to the application require- ments. Due to an O-ring seal, all “com- fort” grinding jars are gas-tight and

For colloidal grinding, the use of a grind- ing jar with a special closure device is recommended. This permits a gas-tight handling inside and outside of the glove box and ensures safe transport of the grinding jar.
For grindings under inert conditions, aeration covers are available. These permit the introduction of gases like argon or nitrogen into the grinding jar.
