The first step in turning ore into useful minerals starts with making the ore smaller by crushing and grinding it under high pressure. Machines called jaw crushers and gyratory crushers are super important for breaking the ore into smaller bits. These big, strong machines squish the ore to make it smaller.

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.
In minerals, elasticity is typically related to the arrangement and strength of chemical bonds between atoms or ions, as well as the overall structure and arrangement of mineral grains. Minerals can exhibit a range of cohesive and elastic behaviors, depending on their chemical composition, crystal structure, and other factors.
The material will crush less if some strong mineral like Quartz is present as seen in the case of OB-Sand. On the other hand, materials like BFS may crush more due to the presence of amorphous media. • The crushing potential of larger size particles is more as compared to that of smaller size particles at a particular stress level.
