The FLSmidth Fuller Airlift System is a pneumatic elevator capable of conveying dry pulverized materials through a vertical pipe to discharge into receivers or bins at a substantially higher level. The use of the Fuller Airlift System is suitable for those materials which can be fluidized by aeration without segregation.

Fuller Airlift Systems are used for the cement, aluminum, copper and chemical industries. Minimum capacity is several hundred pounds per hour on a continuous basis. Capacities of 800 MTPH and lift heights of up to 370 feet (113 meters) have been achieved. But, since Fuller Airlift Systems are engineered for each application, the limits of capacities and lift heights are a matter of design.

Fuller Airlift System Operation and Product Specifications

The Fuller Airlift System is characteristically a predominantly maintenance-free, reliable, vertical conveyor. The only moving parts are the material and air supply. The totally enclosed design provides a completely dust-free operation when connected to a dust collection system. A Fuller Airlift System consists of a feedbin, pipe, disengaging bin (alleviator) and one or two air supplies. The aeration air aerates the bottom of the feedbin, fluidizing the material within. The primary air conveys the material upward through the Airlift pipe. In operation, the Airlift System is a self-compensating system. As the product feed rate increases or decreases, the fluid level and conveying rate conform to such changes. Therefore, the Airlift System matches the conveying rate to the incoming feed, and compensates for any variations of the feed rate.
