UNIVERSAL
APRON FEEDERS
The Universal Apron Feeders consist of a continous steel belt that is made up of overlapping flights or
pans that are connect to and supported by steel chains. The underside of these flights are reinforced and
designed to withstand impact. Apron Feeders provide a positive material flow and with variable speed drives
can provide close control of the feed rate to the crusher. Apron Feeders are well suited for applications that
require moving a high tonnage of coarse material where the impact loads are too severe for other types of
feeders.
Universal Tractor Chain Apron Feeders are of extremely rugged construction. Designed for the demanding
conditions seen for material handling applications in mineral/ore, coal, and aggregate mining and material
processing operations. Universal has six model chain sizes FL4, FD4, FD7, FD9, FD10, and FD11. The
chain pull and application determines which chain size is required for the Apron Feeder. There are fifteen
standard widths and an infinite range of lengths. Each Apron Feeder is custom designed to meet a wide
range of tonnage and application requirements.
For light duty applications we also offer Engineered Chain Apron Feeders. Please contact Universal
Engineering Corp. for more information.
