Airflow sieving technology for zinc powder

2017-07-19

Using a vibrating screen to classify zinc powder relies on a motor vibrating at a certain frequency to allow granular materials to pass through the screen, thus achieving material classification. Due to the open-type screening, the zinc powder screening process produces a large amount of dust, resulting in material waste and loss during the screening process, and causing pollution to the natural and working environments. The air classifier abandons the traditional principle of gravitational potential energy operation and opens up a new way of screening using the kinetic energy of the carrier fluid. It uses high-speed airflow as a carrier in a closed state, allowing the fully dispersed zinc powder particles to be sprayed onto the screen with sufficient kinetic energy to achieve rapid classification. In simple terms: the air classifier uses the zinc powder

　　Vibration sieving of zinc powder relies on a motor vibrating at a certain frequency to enable granular materials to pass through the screen, thus achieving material classification. Due to the open-type sieving, the zinc powder sieving process generates significant dust, resulting in material waste and loss, and causing pollution to the natural and working environments.

Airflow sieving abandons the traditional principle of gravitational potential energy operation and opens up a new path for sieving using the kinetic energy of the carrier fluid. It utilizes high-speed airflow as a carrier in a closed state, allowing fully dispersed zinc powder particles to be ejected towards the screen with sufficient kinetic energy, achieving rapid classification. In simple terms: Airflow sieving utilizes the characteristics of zinc powder particles being small, light, easily floating, and having good fluidity, fully dispersing them into the airflow. The zinc powder no longer agglomerates but passes through the screen as individual particles with the airflow. Therefore, airflow sieving boasts high output, high efficiency, no screen sticking, no clogging of screen holes, precise fineness, stable output increase, reduced power consumption, better quality of finished powder passing through the screen, and no oversized mixing phenomenon. It can select zinc powder of 10um, reaching the sub-nanometer level.
