-
Standard equipment includes a special two-pump asphalt meter for high precision and accuracy. -
Two divided 2.44 x 3.04 meter (8 x 10 ft) cold-feed bins feed up to four sizes of aggregate. -
Nomad features the largest knock-out box in its class, returning more fines to your mix. -
An internal auger in the knock-out box continually feeds captured fines to the mix. -
The drag conveyor features an integral hopper that serves as a surge bin for loadout. -
Each compartment of each aggregate bin has its own independently-adjustable feed gate. -
Heavy-duty flights inside the Nomad drum properly veil aggregate through the burner flame. -
Nomad uses stronger, more durable trunnions and drum tires than other plants in its class. -
Adjustable discharge gates and feed belts with variable-frequency drives (VFDs) allow precise control of aggregate size & feed rates. -
A slinger conveyor mounted just below the burner feeds aggregate into the drum dryer. -
Idlers keep the drum in position as it turns on four adjustable, belt-driven trunnions. -

-
An auger returns captured baghouse fines to the twin-shaft coater for mixing. -
Mixing of aggregate, fines and liquid asphalt cement (AC) occurs in the twin-shaft coater. -
Finished mix is discharged into the base of the plant's drag conveyor. -
The Nomad baghouse includes air compressor, caged ladder and handrails.Ships complete
The Nomad baghouse ships complete with air compressor, internal collecting auger and caged ladder and handrails. The lower section of the baghouse forms a hopper for the collection of fines.
-
The inertial separator is mounted on the baghouse inlet.Inertial Separator
An inertial separator removes the majority of dust from the exhaust gas stream prior to the filter bags. Remaining dust and small particulate adheres to filter bags that are suspended internally from the baghouse roof.
-
An internal collecting auger at the base of the hopper carries fines out of the baghouse.Air Flow
Powerful bursts of air are injected into the filter bags to make the dust break away and fall into the hopper below. The collecting auger that runs the full length of the hopper carries this dust (or fines) out of the baghouse.
-
This dedicated auger returns fines to the mix.Baghouse Fines
Fines collected in the baghouse are returned to the plant's twin shaft coater by a dedicated auger.
-
Drive motor for the internal auger is accessible from the ground. Two augers are available.Easy Access Maintenance
Access panels at the top of the baghouse allow easy changing of filter bags. The baghouse also has multiple access doors for internal inspection and maintenance.
-
The Nomad surge bin includes a drag conveyor and batcher.Surge Bin
The surge bin is available in either 45 or 90 metric ton capacity (50 or 100 ton). Each surge bins includes its own drag conveyor with batcher. The drag conveyor features a full-length stairway with platform around the batcher.
-
Drag conveyor features a chrome-carbide steel liner for superior durability.Drag Conveyor Chain and Liners
The drag conveyor is built to last. It features a chrome-carbide steel liner for durability and a heavy-duty drag chain.
-
Segmented, bolt-on sprockets allow for easy maintenance.Drag Conveyor Sprockets
The Nomad drag chain has segmented sprockets for easy maintenance. The conveyor discharge opening is set back from the head sprocket so that the mix is fully discharged from each flight. This eliminates carry-over of residues that can cause excess wear of the head sprocket and chain.
-
Low-level and high-level switches prevent over-filling of the surge bin.Access Panels
Access panels are provided along the top of the conveyor and on the batcher for internal inspection and maintenance. Low-level and high-level switches inside the surge bin prevent over-filling.
-
Multiple silos and truck scales are available.Available Options
Multiple silos, truck scales and load-out printing systems are available.
-
Standard control house.Control House
The air-conditioned control house is trailer-mounted for easy portability. It also includes heating, lights, internal power outlets and a sliding ticket window.
-
Numerous options for larger control houses are available to meet your requirements.Controls
Controls include three temperature controllers, burner management controller, and PLC (programmable logic controller) for control of mixing. An emergency plant shutdown control enables the operator to shut down the entire plant.
Motor controls enable the operator to turn off/on power to motors that operate the air compressor, exhaust fan, drum drives, drum mixer burner blower, drag conveyor, slinger conveyor, fines-return auger and fuel pump. These controls also provide the plant operator with control of mid-stream start/stop.
Burner Controls enable the operator to:
- Choose manual or automatic process control
- Preset mix process temperature
- Preset the mix temperature limit
- Preset the stack temperature limit
- See burner status
- Reset the flame safeguard controller
- Turn on burner pilot
- Turn on burner main flame
- See status of limits
- See status of flame failure
- Silence the burner alarm
-
Motor control centers are available options.Available Options
Larger control houses, motor control centers (MCC), etc. are available to meet your specific requirements. In addition to the standard drum burner that is fired on natural gas, optional burners are available that can operate on propane gas, diesel fuel, or heavy fuel and recycled waste oil (with an optional heavy fuel preheater). Low NOx burners and numerous other environmentally pro-active options are also available.
-
Plant controls are mounted on a centralized control panel.Centralized Controls
All Nomad plant controls are centralized on a panel located in the climate-controlled control house.

The standard plant configuration includes portable drum mix unit (with integral aggregate system, drum mix unit, knock-out box and wet scrubber), drag conveyor with hopper, and control house.
The Standard Nomad is the most compact design.
Split Plant
A variation of the standard plant, split into two loads.
A detachable aggregate system (2 or 3 bins) delivers maximum portability.
Expanded Plant
The expanded plant configuration includes independant aggregate system, scalping screen, parallel-flow dryer, baghouse, twin-shaft coater, drag conveyor, and single or multiple surge bins or storage silos.
The larger capacity Nomad expanded plant features an independent aggregate system, a baghouse and a storage silo.

Nomad Surge Bin
Each Nomad surge bin includes its own drag conveyor with batcher.
Nomad Controls
All plant controls are mounted on a centralized panel inside the control house. All of the plant's motors and switches are pre-wired and factory tested. Quick-plug connectors aid in rapid plant setup.
