The forced ventilation inside the airflow crusher can play the role of classification and diffuse heat. The machine is equipped with a slag removal system, which can remove sundries and residual hard grinding stones in the machine during operation, which is conducive to improving product quality, ensuring normal production capacity and reducing wear. The particle size of the product can be adjusted by the air volume in the machine and the glare between the conical part and the blade. It can form a variety of systems with micro powder classifier for different crushing requirements of various minerals.
The airflow crusher and the induced draft fan of the cyclone separator dust collector form a complete crushing system. After filtering and drying, the compressed air is sprayed into the crushing chamber at high speed through the Laval nozzle, and the materials are sprayed at the intersection of multiple high-pressure airflow, After being repeatedly collided, rubbed and sheared, the crushed materials move to the classification area with the updraft under the suction force of the fan. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classification wheel to collect the coarse particles and drop them to the crushing area for further crushing.
The airflow crusher is a high-speed airflow composed of high-pressure gas (compressed air, superheated steam or other gases) injected around the crushing chamber and solid material particles. It is constantly impacted tangentially by the airflow injected from different angles, so that the solid particles in the mixed airflow are refined by mutual impact and friction. The product can be free from pollution, and because the temperature generated in the crushing process is very small, it is conducive to crushing materials with low melting point. When crushing toxic, flammable or radioactive materials, superheated steam is often used to prevent outward diffusion. This is because all the materials can be precipitated when the steam condenses. The airflow crusher uses the material to obtain huge kinetic energy under the action of high-speed airflow, resulting in high-speed collision and severe friction between material particles in the crushing chamber. At the same time, the high-speed airflow has shear effect on the material, so as to achieve the purpose of crushing materials.
