Behind room, the material situation handled both can be kept to be in the level being closer to, make to maintain a kind of dynamic equilibrium in pulverizing chamber
State.
Multiple air jet pipes 4 are additionally provided with inside pulverizing chamber, multiple air jet pipes 4 are crushed along the first grinding rotor 21a or second
Rotor 21b axial directional distribution, air jet pipe 4 it is closed at one end, the other end is connected to external air-source treater.Specifically, it sprays
Multiple high pressure nozzles 40, the oral area of high pressure nozzle 40 and the first grinding rotor 21a or the second grinding rotor are equipped on tracheae 4
The position 21b is opposite, and on the extended line of the radial direction of the first grinding rotor 21a or the second grinding rotor 21b.Air jet pipe
The high pressure nozzle 40 being arranged on 4 can spray stronger air-flow and blow to the diameter of the first grinding rotor 21a or the second grinding rotor 21b
To direction, circulation layer can be effectively destroyed, the bulky grain in circulation layer is blowed into grinding rotor and mixes progress with little particle
Further crush；In addition, bulky grain is blown to grinding rotor, the little particle after crushing at this time may pass through sieve pore, improve powder
Broken efficiency；In addition, the gas that high pressure nozzle 40 sprays blows to grinding rotor, cooling crush rotor and bearing, its damage is effectively reduced
Consumption, reduces subsequent maintenance cost.
Further, the material baffle structure 23 for destroying circulation layer, material baffle structure 23 and pulverizer are equipped at the top of pulverizing chamber
The inner wall of body 2 is fixedly connected, material baffle structure 23 along the first grinding rotor 21a or the second grinding rotor 21b axial directional distribution, and
Material baffle structure 23 is located in the tangential direction of hammer leaf rotation of the first grinding rotor 21a or the second grinding rotor 21b；Material baffle structure
The width on 23 tops is greater than the width of its underpart, and the cross-sectional shape of material baffle structure 23 is not limited to shape shown in figure, can
For the rule such as up-side down triangle, semicircle or irregular shape.
At this point, the material of larger particles high-speed motion in pulverizing chamber, to form circulation layer, circulation layer is located at hammer leaf week
Outward.The position of material baffle structure 23 is in the first grinding rotor 21a and the hammer leaf of the second grinding rotor 21b is rotated to highest
In the tangential direction of point.Herein it should be noted that the extreme lower position of material baffle structure 23 is lower than the first grinding rotor 21a or the
The hammer leaf of two grinding rotor 21b is formed by the highest point of locus circle, and material baffle structure 23 will not mutually be hit with hammer leaf.When compared with
Bulky grain will bump against when moving at the top of pulverizing chamber with material baffle structure 23, and the size and Orientation of larger particles speed becomes
Change, larger particles will be crushed through grinding rotor together with smaller particle at this time, ensure the powder of pulverizer so on circulate
Broken efficiency gets a promotion.
Further, material baffle structure 23 is symmetrical about the central axes of pulverizing chamber, and the outer wall of material baffle structure 23 is equipped with along it
The detent projection portion of length direction distribution.The detent projection portion of the outer wall setting of material baffle structure 23 can change circulation to a greater degree

Second sieve 3b, the first sieve 3a and the second sieve 3b of broken rotor 21b cooperation is arc sieve, the first sieve 3a and second
The junction of sieve 3b is located at the first grinding rotor 21a between the first grinding rotor 21a and the second grinding rotor 21b
And second the upper surface of the first sieve 3a between grinding rotor 21b and the second sieve 3b be all provided with and be equipped with the first tooth plate 25.When
Material movement to pulverizing chamber bottom and when moving upwards, the larger particles in circulation layer collide with the first tooth plate 25, compared with
Larger change occurs for bulky grain speed and size, carries out collision grinding into grinding rotor.
Further, crush and be additionally provided with the second tooth plate 27 on the inner wall of body 2, the second tooth plate 27 be located at the first sieve 3a,
On the inner wall of the crushing body 2 of the top of second sieve 3b.When grinding rotor is rotated towards the inner wall direction of pulverizing chamber, circulation layer
In larger particles collide with the second tooth plate 27, larger change occurs for larger particles speed and size, into grinding rotor
Collision grinding is carried out, the crush efficiency of material is improved.
Further, the pulverizing chamber for crushing body 2 is drops.Can effectively it be changed using drops pulverizing chamber material bed
Distribution destroys the circulation layer of material.Specifically, material enters after pulverizing chamber under the action of grinding rotor, first
Circle, it is then for linear motion, generate refraction after, acceleration is reduced suddenly, generate backward acceleration after, and with hammer
Piece bumps against, and continues to circle.So on circulate, then cooperate material baffle structure 23 and each tooth plate, thus significantly more efficient
Destroy the circulation layer of material, and be not in it is big outside, small well-bedded mixing circulation inside, so that material is begun in pulverizing chamber
It is in admixture eventually, greatly improves crush efficiency.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, the utility model
