Maximising productivity from secondary cone crushers

May 23, 2016 · For example, a secondary cone crusher operating at a 25mm CSS should have its feed relatively free of minus 40mm fines. By removing these fines prior to crushing, a more efficient head movement can be achieved as the coarse particles are easily broken into smaller particles due to the voids created in the crushing chamber.
