PROFESSIONAL AUTOMATIC SOLUTION FOR BULK STORAGE AND RECLAIM.These heavy-duty, track-driven systems are designed for continuous operation under the most challenging conditions. When higher-volume

delivery is required, or when handling materials with poor flow characteristics, track-driven reclaim systems are often the best solution. Storage

structures for this series range from 6m-20m in diameter, and are available in steel bolted tanks or, optionally, in monolithic concrete silos.

Track-Driven Silo Reclaim SystemsModel 298, 698, 1098

Hydraulic AdvanceThe hydraulic advance system

provides the flexibility and

sensitivity of adjustment to

match advance speed with

torque requirements.

Rugged Gear TrainThe track driven reclaimers

offer advanced design

gearboxes to accommodate

higher torque in the reclaim

auger power train.

Center DomeFor free-flowing materials an

optional center dome helps

create mass flow and prevents

segregation. Laidig domes

feature a hydraulic safety door

to allow secure maintenance

inside the dome.

Reclaim Auger ShieldWhile producing an efficient

conveying surface, a reinforced

shield on the trailing side of the

reclaim auger maintains auger

alignment despite the

extremely high stresses

encountered in many

installations.

Greasable Reclaim BearingLaidig’s track-driven systems

feature a lubrication system

allowing simplified

maintenance from inside the

hopper, even when the silo is

under full load.

Hydraulic Track DriveThe track drive powers the

reclaim auger into the stored

material with a unique

self-cleaning track shoe and

sprocket assembly.

Accessible Hopper DesignThe improved Laidig hopper

increases accessibility and

maximizes capacity. The

large-sized access door

simplifies routine inspections

and preventive maintenance.

Auger TrackThe reclaim auger shoe grips

the ductile iron track, keeping

the auger firmly in place as it

undercuts the stored material.

AUTOMATED HIGH-DELIVERY RECLAIM SOLUTION COMBINED WITH HIGH-VOLUME VERTICAL STORAGE.Based on Laidig's decades of unequaled experience in track-driven reclaim systems, the 2098 and 2198 DOMinator combine the next generation

automated high-delivery reclaimer with high-volume dome or super-silo storage. These storage and reclaim systems provide cost-effective

solutions for high-volume applications, providing the capacity up to 30000MT.

DOMinator™ Dome and Super-Silo SystemsModel 2098, 2198

Local Control StationAn intelligent control system,

preprogrammed with all

necessary internal logic,

simplifies integration into main

systems and gives local control

if needed. An HMI (Human

Machine Interface) screen

displays status of operation and

faults. Remote monitoring of all

operations is available.

Motion SensorThe advance motion detection

system features a motion

sensor and target wheel

located inside the hopper that

monitors the advancement of

the reclaim auger around the

silo.

Flighting OptionsLaidig’s exclusive cupped

flighting reduces starting torque

and can increase delivery rates.

Optional knifed flighting is used

for some applications,

especially in the wood industry.

Sonar Sensing System (Optional)For materials displaying uneven

flow characteristics, sonar

sensors installed help manage

flow rates. These sensors can

be omitted in semi-free flowing

meal-type applications.

Massive Reclaim Auger: A large-diameter reclaim auger (up to

36in) is powered by Laidig’ energy-efficient reclaim drive

system (150 HP). The rugged auger shield provides highly

efficient material conveyance.

Rugged Center Bullring: Reclaim auger, shield, and gear

motor are mounted on a rugged, large-diameter, rotating

bullring to provide rigid support.

Variable-Speed: Easy-Access Perimeter Service Area The

Perimeter Access Area allows easy service of the advance drive

system, and is protected with a reinforced high-strength steel

shield fully integrated with the storage structure.

Track-Driven Advance: Laidig unique self-cleaning track-driven

reclaim advance ensures dependable variable-speed advance.

High-Efficiency Cutting Blades: Austempered

ductile-iron cutting blades

provide high efficiency

reclaiming, reduced

starting-torque, and minimal

reclaim advance resistance.

Multi-Speed Reclaim Rate: A heavy-duty four-speed gearbox

delivers ultra-high torque at low

reclaim speeds for reliable start-up

under heavy loads. A 3:1 transmission

ratio allows faster reclaiming when

high discharge rates are required.

Enclosed Conductor Bar System: Electrical power for

the reclaimer is transmitted to

the rotating chute and reclaim

drive systems via the fixed

enclosed conductor bars.

Customized Control System: A PLC-controlled Local Control Station

(LCS) is custom designed for full

integration with the customer’s Main

Control Station. Optionally, Laidig can

provide the Main Control Station.
