Airflow Screen, also known as Centrifugal Screen, is a high-efficiency screening device specially designed for light-specific-gravity micro-fine powders.Different from traditional vibrating screens and cyclone airflow screens, its core design logic is as follows:the primary function of the airflow is to seal the bearings and prevent powder from intruding;material screening is achieved by the strong dispersion and projection of internal rotating blades.It mainly solves industrial pain points such as screen clogging and bearing jamming caused by powder ingress for light-specific-gravity, easily agglomerated and easily adhered powders, making it a special screening machine for light powder.

cylindrical screen：The fully enclosed cylindrical structure ensures uniform screening without dead zones, minimal screen blockage, and strong rigidity, significantly enhancing the screening precision and throughput rate of fine powder.
blade：The spiral streamlined design effectively disperses and evenly pushes materials, reducing material adhesion and accumulation, thereby significantly enhancing screening efficiency and operational stability.
observation mirror：With its high-definition sealed and visible design, real-time monitoring of internal material movement and screen status can be achieved without the need to stop the machine or open the cover, making it safe, intuitive, and convenient.
Integrated base with upper and lower flanges for superior strength.
Customizable, fully enclosed bottom barrel for durability in acidic and alkaline environments.
The bucket-type feeding port facilitates manual feeding of small bags.
Customizable discharge reversing valve for closed screening.
Stainless steel is smoothly polished, free of burrs and contamination of materials.
Customizable to accommodate different downstream devices.
With strong and stable power, precise speed adaptation, durable dust-proof sealing, low noise, and energy saving, the equipment ensures continuous and efficient operation, with a low failure rate and long service life.
The spiral feeding system ensures uniform screening by feeding material uniformly forward.
The transmission disc is well-concentric, effectively connecting the motor belt drive.
The airflow screen relies on the centrifugal projection of rotating blades combined with airflow sealing protection to achieve continuous screening of light-specific gravity fine powders,For materials with normal specific gravity, ultrasonic vibrating screens can be selected
The main machine cylinder adopts a fully enclosed sealing structure to prevent dust spillage, and is divided into a screening area and a discharge area. The material options include carbon steel and 304 stainless steel.
The rotary dispersing and screening assembly comprises a main shaft and high-strength dispersing blades. It achieves material dispersion, projection, and centrifugal propulsion through high-speed rotation, serving as the core executing component of screening.
The screen cylinder is equipped with a cylindrical screen, whose mesh size can be changed as needed. Fine powder passes through the screen while coarse residue is retained and graded.
The dedicated fan for the airflow sealing system, coupled with the air seal chamber, forms an airflow barrier at the position of the main shaft bearing, specifically preventing fine powder from entering the bearing.
The upper/side feed inlet, lower fine powder discharge outlet, and end coarse residue discharge outlet of the feeding and discharging system enable continuous automated operation.
The main motor of the drive and frame, coupled with the transmission mechanism and a stable frame, ensures smooth operation and low noise of the equipment.

Can heavy-specific gravity materials be screened? Answer: Because its screening core is "blade dispersion + centrifugal projection". Light-specific gravity materials (usually <1.0g/cm³) can be easily dispersed and projected by the blades onto the screen, ensuring smooth screening; heavy-specific gravity materials (such as metal powder, quartz sand, etc.) cannot be effectively projected by the blades due to their own weight. This not only results in extremely low screening efficiency but also impacts the screen, wears the blades, and even damages the equipment. Therefore, it is not recommended for heavy-specific gravity materials.
