1. Little space, low civil engineering cost; 2. Less steel consumption, low energy consumption; 3. High capacity, less total investment; 4. The wearing parts have long service life, achieve low running cost; 5. Small vibration, less dust, simple to design movable station; PFH ultrafine crusher is a single machine and also a new type of ore crushing device with high input, high crushing ratio, high output and low energy consumption which can crush three sections. It is reasonably designed and elaborately manufactured, belongs to the advanced crushing machine in the world. Low speed, big torque, axial symmetry equilibrium design: PFH ultrafine crusher provides less than 2M/S impact velocity of movable teeth, effectively solves worn grinding material and gouging abrasion caused by vibration, noise and high speed, prevents rock ore from impedance due to high speed. An upright main shaft linkage for cutting and rolling: Main shaft linkage of PFH ultrafine crusher is adopted a driving component system to conduct cutting from top to exert big rock ore with impact, bending and point pressure in the controlled condition, also conducts rolling from bottom, applies the fine granular ore at a rolling force in the laminating condition, so fulfills forcing as different categories, conforms to mechanical characteristics of rock ore, saves labor and energy. Large area design: The cutting device of PFH ultrafine crusher, besides the blanking opening at lower circumferences of inner cone and outer cone, the blanking hole among teeth of inner cone and outer cone enlarges the blanking area; granular rock ore from rolling section is crushed down by roller and forced to fall from long holes of roller base, whole unit discharges smoothly.
