The cyclone blades in the tunnel furnace are deployed throughout the entire convective drying system, which is set according to the principle of gas motion. The layout of the cyclone blades in the tunnel furnace is simple, easy to manufacture, and can obtain high circulating air. The high dust content in the gas can also be directly dispersed, and the pressure loss is relatively small. There are no moving parts, so it is durable. Apart from abrasives, there is no disadvantage of fine powder adhering to the inner wall of the cyclone disperser.

Under normal circumstances, theoretically, the cyclone blades of the tunnel furnace can capture about 5 μ The powder classification can reach over 90% for powders above m. However, in actual production and operation, due to environmental factors, improper use or unsatisfactory manipulation, the actual effect is not as accurate as expected. Because usually only 50% to 80%.

Tunnel furnace cyclone blade, also known as centrifugal force disperser, is a centrifugal force generated by the rotation of air containing fine powder, which disperses fine powder from the gas. Strictly speaking, the air flow environment of the cyclone blade is quite large. Due to the condensation and dispersion of fine powder, the rebound effect of the wall on fine powder, and the friction between particles, the dispersion mechanism is very large, and theoretical research has never stopped.

After the air containing fine powder enters the cyclone plate of the tunnel furnace, it rotates along the inner wall from the outer wall. With high-speed rotation, a parabolic curve of eccentricity is formed, and the rotation rate gradually increases, and particles in the airflow receive more centrifugal force according to the law of conservation of momentum. Due to the centrifugal force generated, the dispersion rate is several hundred or even several thousand times higher than that of gravitational settling, causing fine powder to disperse from the rotating airflow and scatter along the wall surface.
