The liquid nitrogen circulates through the system and is continually replenished from an Autofill system in the exact amount which is required to keep the temperature at -196 °C. Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe.

The size and quantity of grinding balls, the presence of wetting liquid, milling speed, and temperature are important factors in an attritor mill. The drawback of attritor mills is the extremely high degree of wear during operation on the mill bodies, which increases the overall cost of mill operation and causes contamination of the biomass ...

Wet milling with IKA's inline machines is a safe and efficient alternative to dry grinding. Dry grinding creates a lot of dust which causes the need for proper filtering systems. This can be of particular importance during grinding of substances whose dust, when mixed with aerial oxygen, can result in explosive mixtures.
