Inline screening is typically used as a safety screening in closed pneumatic systems. Common is the installation of an inline screener or sifter between a tanker and a silo or after a product pick-up station, like a feeding hopper or bag tipping station. The aim is to avoid contaminants like residual bits of packaging or lumps to enter the silo or the buffer hoppers via the pneumatic conveying system. Further, inline screeners can be used for breaking lumps and to aerate powder raw materials. AZO Inline Screeners can be used with all free-flowing, powdery bulk materials.
