The Dodge screw conveyor torque arm is a critical component in sand and aggregate processing plants, ensuring reliable power transmission for material handling. Designed for heavy-duty applications, it integrates seamlessly with screw conveyors used in crushing, screening, and washing systems.

– Robust Construction: Cast iron housing with precision-machined gears
– Torque Capacity: Ranges from 500 lb-ft to 12,000 lb-ft (678-16,271 Nm)
– Mounting Options: Top, side, or bottom configurations
– Standard Ratio: 1:1 to 5:1 available
| Model | Max Torque (lb-ft) | Shaft Diameter (in) | Weight (lbs) |
|---|---|---|---|
| DSTA-500 | 500 | 2.5 | 85 |
| DSTA-2000 | 2,000 | 4.0 | 220 |
| DSTA-5000 | 5,000 | 6.0 | 480 |
In typical sand production plants (200-500 TPH capacity), the torque arm connects screw conveyors transporting crushed material between:
1. Primary jaw crusher → Vibrating screen
2. Sand washer → Stockpile conveyor
3. Tertiary cone crusher → Final grading screen
Q: How often should lubrication be performed?
A: Every 400 operating hours or monthly under normal conditions.

Q: What indicates excessive wear?
A: Unusual vibration patterns or temperature exceeding 160°F (71°C).
Q: Can it handle wet aggregate?
A: Yes, when equipped with IP65-rated seals.
A Texas-based operation replaced conventional couplings with Dodge torque arms on their 350 TPH washing line:
– Reduced downtime by 37%
– Extended service intervals
