Working principle: air flow pulverizer structure
It is widely used in chemical, mineral, metallurgy, abrasive, ceramics, refractory materials, medicine, pesticide, food, health products, new materials and other industries.
In recent years with the superior performance of ultrafine particles is constantly affirmed, more and more researchers began to pay attention to the research work of microfine powder manufacturing.
Air flow milling technology as an important method of ultrafine powder system preparation, has become one of the preferred methods for the development of a variety of high-performance micropowder materials.
With the air mill to crush the material to get a uniform fineness of the product, powder size distribution is narrow, high purity, the surface of the particles is smooth, regular shape, good dispersion.
Crushing process of the material is subject to less pollution, and even can be done without pollution and sterile environment, so it can be applied to food, pharmaceuticals and other areas that do not allow contamination by foreign objects of the ultra-fine powder crushing.
Working principle: the structure of the airflow mill
Air flow pulverizer and cyclone separator, dust collector, induced draft fan to form a complete set of pulverizing system.
Compressed air is filtered and dried, and then injected into the crushing cavity at high speed through Laval nozzle.
In the intersection of multiple high-pressure airflow, the material is repeatedly collision, friction, shear and crushed, crushed materials in the fan under the action of the pumping force with the upward movement of the airflow to the classification area,
in the high-speed rotation of the classification turbine produces a strong centrifugal force,
- so that the coarse and fine materials are separated to meet the requirements of the size
of fine particles through the grading wheel into the cyclone and dust collector collection,
the coarse particles down to the crushing area to continue to crush.
