The mill of rotor has 8 rotor blades.Under some situations, each mill can increase or decrease rotor leaf according to actual needs
Piece, the material of rotor blade can be made of wear-resistant ceramic.Each described rotor blade is high speed impact type rotor blade, material
Very big power acceleration is obtained in strong centrifugal field, in a variety of crushing mechanisms such as impulsive force, impact force, shearing force and frictional force
Synergy under be stripped crushing.In order to improve the crush efficiency of grinding material, increase mill wall in cavity.The effect of mill wall
It is after material particles are accelerated by the impact comminution of rotor blade, under the collision effect with mill wall, to make material again by powder
It is broken.For mill wall construction form significantly affecting on crushing effect, mill wall is made to the special tooth profile of auricle shape.
Specifically, described rotors at different levels (mill) constitute the rotating disk of spacing, homoaxial three disks counter-rotating
Structure so that the impact velocity after material accelerates through three disk counter-rotatings is up to more than 100m/s, its impact velocity is close to air-flow
The level of mill, larger impact energy exacerbates the speed of the broken and mechanical activation of cell membrane, and higher impact velocity also increases
Add the probability that plant cell is mutually collided, be more beneficial for the broken of material so that the broken efficiency of equipment is significantly increased.
Further specifically, three rotor structures of described multistage cyclone eddy current mill apparatus constitute special ladder grinding
Cavity configuration so that multistage cyclone eddy current mill apparatus formation separation, three fracture area structures that order is broken.Unique ladder is ground
Mill chamber causes material to be raised speed quickly in intracavitary, and then produces in opposite head-on collision huge crushing energy, and is formed and set
The 1st standby fracture area；The high speed impact of intensive tup on the inside of stepped cavity, forms the 2nd fracture area and the 3rd fracture area of equipment, makes
Obtain the broken further refinement of powder.Material through the 1st fracture area, the 2nd fracture area and the 3rd fracture area by chamber multistage impact, strike,
Split it is broken be combined, improve broken efficiency.This is other impact grindings as not available for following closely mill, crossing current mill, Ball-stirring mill etc..This
Be because described multistage cyclone eddy current mill apparatus reasonably crushed using the 1st fracture area, the 2nd fracture area and the 3rd fracture area it is suitable
After sequence, mutually collided in the 1st fracture area large granular materials of rotating disk, impact velocity can be more than 100m/s.Material after crushing
Enter the 2nd fracture area and the 3rd fracture area from the 1st fracture area of rotating disk under the drive of negative-pressure air-flow, then to the material after refinement
Impacted.The 2nd fracture area and the 3rd fracture area material by the successively sharp blow of multilayer impact components, plant cell quilt
Further crush.This broken order is more beneficial for extension impact components, the service life of wearing piece.Examined by relevant authority
The dependency number of department is it was demonstrated that under the conditions of same process, the power consumption of the machine specific yield can compared with airflow milling, crossing current mill etc.
To save more than 50%.
Further, also there is airslide disintegrating mill, the air-flow on the stator (7) of described multistage cyclone eddy current mill apparatus
The pulverizing chamber surrounding of pulverizer is generally provided with the special high pressure admission nozzle arranged in opposite directions, empty by the compression for purifying and drying
Gas is projected from nozzle, forms supersonic flow, and material collides in high velocity air focus center, is crushed in moment.Through powder
Broken particle rises to grading room with air-flow, and qualified particle enters cyclone separator with air-flow, finally obtains required product, tail
Gas is discharged into deduster.The turbine type hierarchy system set in grading room, can obtain a few micrometers of even more fine powders.
When the material being crushed in pulverizing chamber is promoted by ascending air, the same particle in turbine rotational section edge will be by
The effect (being rotated and the centrifugal intertia force produced and gas-flow resistance by turbine) of the different power of two kinds of centrifugal force field.When particle is larger
When, suffered centrifugal force is more than resistance, and bulky grain flies to grading room wall along turbine tangential direction, be then back to pulverizing chamber again by
Crush.When particle is smaller, now centrifugal force is less than resistance, and little particle enters turbine interior with ascending air, through cyclonic separation
Device is collected as qualified products.Described device is just being combined with the principle of turbine grinder and airslide disintegrating mill, while overcome again
The deficiency (crushing completely) that airslide disintegrating mill is present, make equipment from it is vertical be changed to it is horizontal, you can with according to material each group dtex
Property, after being crushed in part, form mixture and next separation link is delivered to by high-pressure suction fan, here, high-pressure suction fan is not
