Most sample materials can be reduced to the required analytical fineness at room temperature by choosing a mill with a suitable size reduction principle (impact, pressure, friction, shearing, cutting). However, there are limits for size reduction at room temperature, for example when even a small temperature increase affects the sample in a negative way; or when the material is very elastic and the above mentioned size reduction principles only cause deformation. The perfect solution for these types of samples is cold or cryogenic grinding. This involves grinding aids such as liquid nitrogen (-196 °C) or dry ice (-78 °C) which embrittle the sample by cooling and make it break more easily.
The Webinar offered by Retsch "Cryogenic Grinding: How to Treat Thermo-Sensitive Materials" will explain specifically how to perform a correct and effective cryogenic grinding (Liquid Nitrogen / Dry Ice) with particular attention to typical applications in the following sectors:
- Automotive sector
-Cementer - Chemist
- Rubber
- Plastic
- Ecology / Energy
During the webinar, our expert will show the most suitable grinding systems for several applications such as polymers / secondary solid fuels / plastics / resins / rubbers / tires and much more.
In this webinar we will explore this topics
