Flour Milling Air Lock
An airlock is a machine used in flour mills to separate air from the product and prevent
the atmosphere from entering the discharger or deduster. It's installed at the outlet of a
discharger or deduster to discharge materials or dust continuously and timely.
Air Lock purposes
Airlocks have several purposes, including:
Sealing device: Prevents loss of air while maintaining a flow of bulk materials between
components in a pneumatic conveying system
Volumetric feeder: Meters materials from bins or silos into a conveying system
Gravity discharger: Discharges materials or dust continuously and timely
Airlocks work with negative pressure and an air seal against leakage. The air-product mixture
enters the chambers created by fixing blades (wings) on the rotor shaft. Due to the precise
tolerance between the body housing and the rotor, the product is separated from air and
discharged regularly without any leakage.
Flour mills require several airlock systems for separating conveying air from the product
consisting of airlocks, cyclones, and air collecting ducts
From the air lock inlet the air-product mixture enters the chambers, which are created by fixing blades
(wings) on the rotor shaft. Due to the precise and standard tolerance between the body housing and the
rotor, the product is separated from air and discharged regularly without any leakage.
