"Developing graphite crushing technology is a step towards a more sustainable mining sector. In the future, the water and energy-saving crushing method will be tested for other types of ore containing critical raw materials. There is still a long way to go before the new crushing method can be applied on an industrial scale.
Tertiary crushing is highly valuable in the mineral processing industry. The degree to which a material is reduced largely depends on how fine the material's final size should be. More stages of crushing = smaller-sized products. For tertiary crushing you will most likely need a smaller impactor or cone crusher.
