Mixer Mill MM 500 control. The MM 500 control is a high energy laboratory ball mill that can be used for dry, wet and cryogenic grinding with a frequency of up to 30 Hz. It is the first mixer mill in the market that allows to monitor and control the temperature of a grinding process. The temperature area covers a range from – 100 to 100 °C.

The grinding process is commonly used as the final stage of processing. It is used to produce elements that require more tolerance and smooth surface. Considering other processing, such as turning or milling, grinding requires very high energy input per unit volume of material removal. A significant proportion of this energy in the process turns into heat in the grinding zone, which …
