A screw 65 is fixedly connected to the guide seat 61 at one end and threaded into the threaded sleeve 64 at the other end.

[0031] The adjustable airflow pulverizer of the present invention has the following significant advantages in terms of beneficial effects:

[0032] 1. Efficient and Flexible Crushing Performance: The clever combination of the accelerator tube 3 and the air inlet pipe 4 accelerates the powder at high speed and sprays it into the crushing chamber 10, effectively improving crushing efficiency. Furthermore, the introduction and adjustable design of the collision element 5 allow the collision intensity and frequency during the crushing process to be flexibly adjusted according to actual needs, thereby achieving precise crushing of materials with different hardness and particle size requirements, improving product adaptability and processing quality.

[0033] Second, precise particle size control: The innovative design of the collision adjustment mechanism allows precise adjustment of the collision member 5's position within the pulverizing chamber by rotating the threaded sleeve 64, driving the guide seat 61 and the collision member 5 along the adjustment hole. This adjustment method is not only simple to operate, but also significantly affects the collision pattern within the pulverizing chamber, thereby precisely controlling the particle size distribution of the pulverized product and meeting users' high demands for particle size uniformity.

[0034] 3. Stable operation: The sliding fit design of the guide seat 61 and the guide post 62 ensures the smooth movement of the collision part during the adjustment process, avoiding equipment damage or reduction in crushing effect due to shaking or deviation.

[0035] 4. Easy Maintenance and Operation: The adjustable airflow pulverizer of this utility model is designed for easy maintenance. The connection and disassembly of each component are relatively simple, making it convenient for users to carry out daily cleaning, maintenance, and replacement. At the same time, the collision intensity can be adjusted through a simple rotation operation, which greatly reduces the difficulty of operation and improves work efficiency.

[0036] In summary, the adjustable air flow mill of the present invention shows significant beneficial effects in terms of crushing efficiency, particle size control, and operation stability, and has broad application prospects and market value.

[0037] In this embodiment, the collision adjustment mechanism 6 includes a turntable 66 fixed on the threaded sleeve 64. The threaded sleeve 64 is rotated by holding the turntable 66 to drive the screw 65 to move. It is understood that the threaded sleeve 64 can also be driven by a motor to rotate to achieve automatic adjustment.

[0038] In this embodiment, the outer surface of the guide post 6 is provided with graduated markings to indicate the particle size. By providing these markings directly on the outer surface of the guide post, the operator can intuitively understand the current position of the impactor 5 and, therefore, infer the corresponding particle size. This design not only simplifies the operation process but also improves the accuracy and efficiency of particle size control.

[0039] In this embodiment, the adjustable airflow mill of the present invention further includes a cover plate 7 that is removably mounted on the pulverizing body 1 to seal the opening of the pulverizing chamber 10. To facilitate locking of the removable cover plate 7, the outer edge of the cover plate 7 has a lug with a through hole. A stud 71 is fixed to the pulverizing body 1 at a corresponding through hole. The lug is inserted through the through hole into the stud 71. A nut 72 is screwed onto the stud 71 to secure the cover plate 7. To facilitate removal of the cover plate 7, a handle 73 is provided on the outer side of the cover plate 7.

[0040] In this embodiment, the collision member 5 includes a cylindrical section 51 and a collision ball 52 fixedly connected to one end of the cylindrical section 51. The cylindrical section 51 is slidably arranged in the adjustment hole of the crushing body 1. The collision ball 52 is slidably arranged in the acceleration tube 3, and there is a gap between the collision ball 52 and the inner wall of the acceleration tube 3 for powder to pass through. The powder supplied to the acceleration tube 3 is accelerated by the high-speed airflow in the air intake pipe 4, and the powder sprayed into the crushing chamber 10 collides with the spherical surface of the collision ball 52 and is crushed. The collision ball 52 is the main crushing element, and its spherical design can disperse the collision force to the maximum extent, so that the powder can be subjected to uniform and strong impact when it collides, thereby achieving a more delicate crushing effect. At the same time, the gap between the collision ball 52 and the inner wall of the acceleration tube 3 ensures that the powder can pass smoothly and continue to be accelerated by the airflow, further improving the crushing efficiency.

[0041] In this embodiment, a feeding pipe 21 is connected to the feeding hopper 2 to feed the powder into the feeding hopper 2 .

[0042] In this embodiment, a discharge pipe 11 is connected to the pulverizing body 1 above the collision member 5 , and the discharge pipe 11 is communicated with the pulverizing chamber 10 to transport the powder after collision and pulverization.
