To maintain the maximum levels of capacity, gradation and cubical product, a CMB Cone Crusher must be choke fed at all times. The best way to keep a choke feed to the CMB Cone Crusher is with a surge bin or hopper and Feeder that are located prior to the crusher. Choke feeding is almost impossible to achieve without a hopper and Feeder.
