High Speed Sort Gate
The Model 2000 High-Speed Sort Gate (HSG) is an automated sorting system that works with any online analyzer providing a 24 VDC sorting signal — sorting bulk material into two or more stockpiles based on quality parameters such as ash content, at full conveyor speed, updating as quickly as every 3 seconds.
Turn quality data into automatic sorting decisions
Sort at full belt speed
The Model 2000 mounts at the conveyor discharge and routes material to the correct stockpile automatically — no slowdown, no manual step, no operator intervention.
Works with any analyzer
Compatible with any online analyzer providing a 24 VDC sorting signal — including ETI's Model 410, FSEA, and third-party systems.
Sorts into more than two directions
Multiple gates can be linked on the output of the primary gate or downstream — separating material into low, medium, and high-quality stockpiles in a single pass.
Applications
Coal Quality Sorting
In coal preparation plants, the Model 2000 works in tandem with ETI's Model 410 Ash Analyzer or FSEA to automatically divert high-ash or off-spec coal to a reject stockpile — keeping product quality consistent without manual sampling or operator intervention.
Cement & Minerals
Cement producers and mineral processors use the Model 2000 to segregate raw material streams by elemental composition or density. Automated sorting reduces blending errors, improves product uniformity, and lowers the cost of downstream processing.
Multi-Stream Sorting
Multiple gates can be linked — installed on the output of the primary gate or downstream — to sort material into more than two directions. Useful for separating low, medium, and high-ash product into separate stockpiles.
Biomass & Alternative Fuels
Sort biomass or alternative fuel blends by moisture or heating value to maintain consistent fuel quality for combustion processes — reducing variability and improving boiler efficiency.
Key Benefits
Control Modes
Analyzer control
Automatically sorts material based on real-time quality data from any online analyzer providing a 24 VDC sorting signal. Sort decision made every spectral update — as quickly as every 3 seconds.
Manual control unit
Operator-initiated switching via the included remote control enclosure for testing, override, or manual sorting situations.
External controller
Accepts 24 VDC on/off signals from any external plant control system or PLC via the gate controller NEMA enclosure.
How It Works
The Model 2000 mounts at the discharge end of a conveyor and responds instantly to quality signals from a paired analyzer — automatically routing material to the correct stockpile at full belt speed, with no manual intervention.
Analyzer Measures Material Quality
An upstream ETI online analyzer (such as the Model 410 or FSEA) continuously measures material quality — ash, sulfur, chlorine, or other parameters — and makes a sort decision every spectral update, as quickly as every 3 seconds.
Control Signal Sent to Gate
Once a sort decision is made, the analyzer sends a 24 VDC control signal to the HSG. The gate can change position in under one second upon receiving the signal.
Gate Switches at Full Speed
The direct drive gear motor actuates the gate at full conveyor speed — no slowdown, no manual step required. The heavy-duty AR plate weldment and solid-state controls handle continuous industrial duty.
Material Directed to Stockpile
Material is diverted to the appropriate stockpile. Multiple gates can be linked — installed on the output of the primary gate or downstream — to sort into more than two directions.

Technical Specifications
System Components
The sort gate system consists of:
- Model 2000 High-Speed Sort Gate (HSG)Fixed high-speed sort gate mounted at the exit end of a conveyor belt. Includes heavy-duty AR plate weldment, shaft and bearings, direct drive gear motor with couplings, solid-state controls, and field wiring. Updates sort position as quickly as every 3 seconds; changes position in under one second. Gate weight: approximately 750 lbs. Includes gate controller (NEMA enclosure) and remote control enclosure.
Power Requirements
240/480 VAC clean power service adjacent to the electronics enclosure (supplied by customer)
Delivery
Approximately 90 days after receipt of the initial 50% payment, subject to inventory availability at time of order.
Warranty
12 months from date of installation or 15 months from date of shipment, whichever is first. ETI warrants the Model 2000 is free from manufacturer's defects in material and workmanship under normal use.
Plant Integration
The Model 2000 accepts a 24 VDC sorting signal from any upstream online analyzer — ETI or third-party. The gate controller NEMA enclosure also accepts signals from external PLCs and DCS systems. A remote control enclosure is included as standard for manual override. Multiple gates can be linked for complex multi-stream sorting without additional control hardware.
One year of service included
Every ETI system ships with one full year of support — unlimited phone, email, and remote VPN access, plus one scheduled site visit for inspection, calibration, and NRC-required leak tests.
