ASTEC
Recycling work horses
 Astec
RAP systems are offered in a range of configurations, with a variety of
conveyors, screens, grizzlies, lump-breakers, and crushers. The simplest
system consists of one bin, scalping screen, and conveyor. Options include
bulkheads, and either a screen or grizzly to separate lumps and oversized
material.
Recycle bins are designed for free flow of RAP even
with fine RAP in hot weather. At 8 feet, the tops of bins are 2 feet
narrower than regular cold-feed bins, resulting in very steep side walls to
aid free flow. One end-wall is vertical and the other is angled at 75
degrees. Air cannons are standard and keep RAP from compressing in the bin.
The bin discharge opening is tapered to make it
self-relieving. It is wider than that of cold-feed bins and uses a wider
belt feeder.
You can increase production capacity by running the
same grade of RAP through two bins. A swing-hammer crusher or fixed-bar
impactor, commonly referred to as a hammer mill, can be used for breaking
rock and hard pieces of RAP.

GENCOR
Industries, Inc.
Unique bin design
 The
Gencor Giraffe RAP unit combines a bin and feeder, lump breaker, vibrating
screen, and scale conveyor into a single, easily transportable unit. The
unique bin design eliminates material bridging, with steep-sided tapered
walls, self-relieving throat, and welded beater plates on the sides of the
bins. The rack and pinion adjustments allow the bin gates to be easily
raised or lowered to maintain the correct amount of RAP being fed for
precise material flow. The exclusive double-drum RAP lump breaker can easily
reduce RAP material size without crushing the aggregate and is designed with
a unique self-relieving tire- and air-bladder drive system. A long, folding
and reversible bulkhead can accommodate any plant arrangement and provides
for bin loading from either side for optimum versatility on varying
jobsites. All Giraffes come complete with quick-disconnect cabling, budd
wheels, and two-speed landing gear to reduce the cost of setup and
transport. The equipment is backed by world-class product support and
training.
