The work by Bengtsson and Evertsson (2006) showed a similar result, concluding that crusher settings affect the particle shape to a great extent. A model for rock breakage in cone crushers was presented by Evertsson (2000); this model is calibrated with a piston and die test and shows good correlation with full scale tests.
How Vertical Shaft Impact Crushers Work. A VSI crusher works with both soft and hard materials.The material is then deflected from its original path, impacting other particles, and breaking them into smaller pieces. ... such as jaw and cone crushers. VSI crushers are typically used for rocks, ores, minerals, metals, and other materials …
