On the premise of not using traditional vibrating screening equipment to pass the material through the screen through gravitational potential energy, can the screening or impurity removal of powder materials be completed? Perhaps, the use of airflow as a screening power should be explored.
Vibrating screening equipment in the traditional sense relies on a certain frequency of motor vibration to achieve bulk objects passing through the screen to achieve material classification. For non-fragile particles or liquid materials, this is a good screening/filtering method , but for powder materials, under special circumstances such as light specific gravity, high viscosity, easy to generate static electricity or easy to adhere, it is difficult for the traditional vibrating screen to complete the effective treatment of the material.
In this case, combining aerodynamic theory and mechanical engineering theory, Airflow screening machine is designed for fine powder screening process.
Theoretically speaking, Airflow screening machine abandons the traditional principle of gravitational potential energy operation, and opens up a new way to screen the kinetic energy of carrier fluid. It uses high-speed airflow as a carrier in a closed state, so that the fully diffused powder particles Large kinetic energy is sprayed to the screen to achieve the purpose of rapid classification.
In layman's terms: Airflow screening machine makes use of the characteristics of small and light powder particles, easy to float and good fluidity, and fully diffuses them into the air flow. Therefore, the Airflow screening machine has large output, high efficiency, non-stick screen, no blocking of the mesh, and accurate fineness.
The Airflow screening machine has the function of airflow feeding, the function of crushing agglomerates by the feeder and the function of airflow coarse screening. Stable improvement, lower power consumption, better quality of finished powder passing through the screen, can be used with dust removal equipment, vacuum feeding equipment, and even Airflow screening machine.
