Air Swept Screening
Material is conveyed and presented pneumatically to a screen of certain mesh size. Oversize particles are physically blocked from passing through the screen and are directed to an oversize chute for collection. Particles below the mesh size of the screen pass through the screen and are conveyed to a product collector. Screens are continually swept with rotating wand utilizing high pressure air clean the screen and maintain high separation efficiencies between oversize and fine particles.
