Application
Routing Powder to Multiple Destinations in Mining & Mineral
Answer in brief
In mineral plants the diverter takes the full abrasive stream at the point where it changes direction.
Wear concentrates there, and the liner is the part that decides the interval between shutdowns.
- Line the junction and plan the replacement.
- Size the actuator for a loaded, not an empty, valve.
- Watch for oversize that the screen let through.

The problem
Abrasive ore erodes the junction quickly, and an oversize particle can jam a diverter that passes the nominal product without difficulty.
Desired outcome
A junction that delivers the full stream to the selected destination, retains nothing for the next one and holds the line pressure.
Process approach
Heavy-duty pivoting designs with replaceable liners suit gravity streams; pressure conveying is less common at this particle size.
The actuator is sized for the loaded condition, and position switches confirm that the movement completed.
- Liner material matched to the mineral.
- Actuator sized for a loaded junction.
- Inspection interval based on measured wear.
Selection factors
- Largest particle that can reach the valve.
- Material hardness and the liner life it implies.
- Actuation force under load.
- Access for liner replacement.
- Dust control at the junction.
Common failure modes
- Oversize particle jamming the junction
- Liner worn through into the body
- Actuator stalling against a loaded column
- Position not confirmed after a partial movement
