Sterlco SVL Series Compressed Air Loaders - Manual (Page 21)

SVL-A, SVL-B, SVL-C, & SVL-D Self-Contained Material Loaders - Venturi Style 21 of 49
3-2 Method of Functioning
The self-contained venturi loader works according to the
Venturi Principle. An external compressed air supply is
needed to provide the source of compressed air.
A venturi device (A) is integrated in the venturi assembly.
The venturi creates a vacuum in the lower part of the tube
(C) and then conveys the material into the conveyor
hopper using pressurized air in the upper part (B). In the
hopper loader, the material is separated from the air.
The filling level of material receiver is monitored and
controlled by a level sensor located on the sight glass (or
on a flange) of the receiver.
