A kind of operation principle of birotor vertical-spindle hammer crusher of the present invention is：
Material passes through the material flow of material bin formation vertically downward under gravity, and entering rotor center by blanking ring bores cap
Top is simultaneously taken advantage of a situation and is divided evenly into the horizontal stream of multiply, and the rotor in one-level crusher chamber accelerates in road due to rotor spinning
Expect the brute force attack of ripple, produce strength extruding first in the channel and grinding is broken, and in accelerated passage terminal by thrower head
Rotating percussion crushes.
Horizontal stream is accelerated rapidly to 65- in the case where the rotor of high speed rotation applies centrifugal action by accelerated passage
80m/s linear velocity lasing simultaneously obtains huge kinetic energy simultaneously, and this high speed stream is in Turbulent chamber and material bed course（Stone-crash-stone
Type）Or anvil（Stone forges iron type）Hit, the energy between producing fierce kinetic energy and crushing fully is changed and produces collision and crush.Kinetic energy
Be fully converted to crushing energy material can by high speed rotor provide endlessly horizontal stream pursue and attack generation continuous crushing, tangentially
Projectile can also produce high-speed extrusion, grinding crushes.
Material after one-shot is broken, wherein the still large granular materials containing major part, under gravity,
The screening passage for the two-stage crushing top of chamber that large granular materials enter under one-level crusher chamber is screened, the large granular materials of screening
Falling on down again at a high speed on the material separating disc of rotation, large granular materials are evenly dispersed at a high speed on the deflector of rotation by material separating disc,
Large granular materials move along deflector, are vacantly turned after large granular materials leave from deflector end with uniform rectilinear to two level
Sub- outer rim motion, shock plate and the large granular materials of synchronous rotary collide, and realize secondary acceleration of the rotor to material so that mostly
Number material speed reaches more than 60m/s, the large granular materials after secondary acceleration and the screen analysis material and counterpunch board of crusher chamber surrounding
Collision, complete secondary pulse and crush, ultimately form granular size than more uniform, and the preferable material of pattern sphericity is from discharge port
Discharge.
