READ MORE1.Crusher area theory: Von Rittinger P R proposed the area theory in 1867. It is believed that the work done when an external force breaks an object will be converted into surface energy on the new surface area. Therefore, the energy consumption for crushing is proportional to the new surface area during crushing.
READ MORE· This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages.
