Retsch MM 500

Vibratory Mill / Ball Mill (Laboratory)
The MM 500 control is a laboratory device for dry, wet, and cryogenic grinding. It is suitable for hard, brittle, soft, elastic, and fibrous materials and is used in a wide range of fields – from materials research and pharmaceuticals to geology as well as food and environmental analysis.

The samples (up to 10 mm particle size) and grinding balls are placed in the grinding jars. These jars are inserted and positioned on the cooling plates.

Oscillating movements of up to 30 Hz reduce the sample size through impact and friction forces.

Optional cooling can be achieved using various media (LN², water, etc.).

Final particle sizes as small as 0.1 µm can be achieved. The typical grinding process takes between 30 seconds and 30 minutes.

Grinding balls are available in various materials (steel, stainless steel, tungsten carbide, zirconium oxide) and sizes (available from the manufacturer).

The machine offer includes two 125 ml grinding jars (material as shown in illustration). 10 mm hardened steel grinding balls are also included.
