IROCK RAPID DEPLOYMENT SYSTEM MODEL RDS-20
Our largest, most powerful, best in class, inline crushing and screening
system. Able to handle quarry rock, gravel, RAP, or recycle concrete. The
IROCK RDS-20 has it all. Capacities range up to 300 Tons Per Hour depending on material
and site conditions. The RDS-20 can make three products simultaneously,
two sized and one crusher run. Add an optional magnet and produce salvaged
metal from recycled concrete. IROCKS' "I-flow" plant design allows
the top screen deck oversize to return to the crusher or discharge as a
product; the second deck oversize can do the same. This gives the end user
the most flexible plant flow possible, thanks to "I-flow" from
IROCK. The RDS-20 is also one of the best-balanced plants on the market. Each
component is mated to the system to produce a plant that optimizes the
plant's capabilities. Options allow this plant to be fitted to exact job
site requirements. Contact IROCK for complete information and capabilities.
FEATURES OF THE IROCK RDS-20
HOPPER/FEEDER:
Full length fabricated steel plate hopper with supports. Vibrating grizzly
feeder with IROCK's exclusive 5' beveled grizzly section designed to fit
the 4056 impact crusher. This design maximizes the total inlet area to
increase production. Fabricated inlet chute and fines bypass chute. Variable
speed drive is standard.
HEAVY DUTY HORIZONTAL SHAFT IMPACT CRUSHER:
The 4056 hard rock crusher uses a solid one-piece rotor shaft. Ringfeder
locking assemblies fasten the heavy-duty rotor to the shaft. Alloy blow
bars are held in place by quick-change vertical wedges. The square rotor
shell is designed to allow maximum blow bar surface exposure to the incoming
feed material. POWER:
Cat 440 hp diesel engine
 and a 156 kW generator.
VIBRATING SCREEN:
Double deck incline vibrating screen with feed box.
CONVEYORS:
Wide under crusher/screen feed conveyor
with under crusher impact tray.
Wide top deck side discharge conveyor. Flop gate on discharge chute to
direct material to be returned to the crusher or discharged as a product.
Wide second deck reversible, side discharge conveyor is reversible to
direct the flow of material to be returned to the crusher or discharged
as a product.
Wide return conveyor, full-length skirt boards, receiving hopper.
Wide under screen fines conveyor, full length receiving hopper. RDS CHASSIS:
Fifth wheel, triple axle chassis.
PLANT FLOW:
The material to be processed is fed into the hopper. A vibrating feeder
conveys the material over the integral grizzly section of the feeder.
Sized material is bypassed through the grizzly section and around the
crusher to the under crusher conveyor; oversized material is fed into
the horizontal impact crusher. Crushed material is discharged onto the
under crusher/screen feed conveyor and combined with the bypassed material.
All the material on the conveyor is sent to the vibrating screen. Material
that is too large to pass the top deck is discharged onto the top deck
side discharge conveyor, which sends the oversize to a flop gate chute
where it can be sent to the return conveyor for further processing or
it can be discharged as a product. Material that passes the first deck
but not the second deck is discharged onto the second deck side discharge
conveyor where material can be discharged as a sized product or the conveyor
can be reversed to send the product back for further crushing. Material
that passes through both screen decks is collected on the under screen
fines conveyor and discharged to an off plant conveyor as a sized product.
