The raw materials in the silo are transported into the grinding chamber of the impact mill for crushing via a feeding device (the start and stop of the feeding device are controlled by the main motor current of the impact mill). The impact mill uses hammers and toothed plates on a high-speed rotating rotor to impact the material being crushed, leveraging the interaction between the material and the rotor.Intense collision, friction, and shearing occur to achieve ultra-fine grinding of particles.The crushed material is transported by an upward airflow to the classification zone, where a horizontally arranged classifying wheel screens out fine powders that meet the particle size requirements. These fine powders then enter the downstream collection device (dust collector) for collection and discharge. Coarse powders that do not meet the particle size requirements are returned to the crushing zone for further crushing.

This model, in conjunction with the fluid dynamics numerical simulation software developed by the Aerodynamics Research Institute, calculates the *optimal flow field and *ideal pressure distribution to guide the design, significantly improving crushing efficiency, reducing energy consumption, and minimizing over-crushing. This equipment features the following characteristics:

(2) Equipment Features：

1．TheThe machine is a vertical shaft impact crusher, equipped with a classification device inside the crushing chamber. The crushed material is separated by the classification device under the action of airflow. The classification device replaces the conventional screen of a crusher, enabling the simultaneous completion of two processes: fine powder crushing and fine powder classification, resulting in high crushing efficiency.

2．Equipped with an airflow control valve and a stepless speed regulator for the classifying rotor, the product particle size can be adjusted without stopping the machine, and it does not pollute the environment.

3．Unique flow field design and constant gas-solidCompareConcentration control, short residence time of materials in the chamber.ReduceThe materialInInner wall of the cavityofAdhesion.

4. Low energy consumption: It integrates centrifugal crushing, impact crushing, and extrusion crushing, making it more energy-efficient than other types of mechanical crushers.

5. Low wear: The wear-prone parts of the crushing section can be made of composite wear-resistant materials, offering a long service life.

6.The crushing particle size range is wide, and the finished product particle size is betweenWithin a certain range, it is possible toAdjust。

7．Full functionality:

² It can crush needle-like materials to achieve a finished product with a specific aspect ratio.15：1；

² During the crushing process, the temperature rise can be controlled (optional air cooler,The scope of supply shall be subject to the contract agreement.), suitable for crushing heat-sensitive materials;

² It can perform dispersion operations on sintered agglomerated ultrafine materials, with a particle size recovery rate of100%；

² With particle shaping functionality, effectively increasing packing density;

² Material capable of crushing fibrous tissue;

² Can crush materials with high moisture content (≤5%), with a drying function;

² Due to the characteristics of certain materials, some may adhere to equipment. For such materials, manholes can be installed in areas prone to adhesion, allowing for convenient manual cleaning in a timely manner after shutdown due to material buildup.

8Built-in selfShunt-type micro-powder classifierIt has a strong classification effect on ultra-fine powders, resulting in a narrower and more uniform particle size distribution.Concentration。

9．The equipment has a compact structure and a small footprint.

10．Negative pressure production ensures no dust pollution and an excellent working environment.，The dust emission amount does not exceed10mg/m³。

11．High degree of automation.It can achieve one-key start/stop and can be connected to the central control system for remote control.Strong stability, easy to operate.

12The company has specially developed a compartmentalized offline dust removal and collection device for certain highly viscous materials (such as sugar, graphite, materials with high sugar or moisture content, and materials with severe agglomeration at the submicron or nanoscale). This device can reduce the rate of product adhesion to the filter bags during equipment operation. (Optional)The scope of supply shall be subject to the contract agreement.）

13．For flammable and explosive materials..., easily oxidizedThe material can be fully pulverized in a closed system using an inert gas as the medium.Grade,Inert gases are recycled, resulting in low loss.（Optional, subject to the scope of supply as stipulated in the contract.）
