Cooling Spray Nozzles for Mining
Effective cooling protects critical assets, stabilizes processes, and extends component life on crushers, mills, and conveyors. NozzlePro provides mining-ready spray nozzles that deliver controlled heat removal with consistent coverage and efficient water use.
Applications in Mining Cooling
Equipment Cooling
Targeted sprays manage heat on crushers, grinding mills, gearboxes, and bearings to reduce wear and avoid thermal trips.
Material Cooling
Uniform coverage cools hot ore and aggregates at chutes and transfer points to protect belts and improve handling.
Integrated Dust & Heat Control
Dual-purpose systems combine misting for dust capture with light cooling to stabilize temperatures in loading zones.
Benefits of NozzlePro Cooling Solutions
- Reduced Equipment Wear – Controlled temperatures protect bearings, seals, and liners.
- Stable Throughput – Consistent cooling improves runtime and process reliability.
- Water Efficiency – Optimized patterns deliver cooling with less water.
- Lower Maintenance – Fewer heat-related stoppages and longer service intervals.
Cooling Planners & Reference (Illustrative)
Required Water Flow from Heat Load
Rule-of-thumb sizing for water cooling. Assumes ΔT = 20°F water temperature rise.
| Heat Load (kW) | Approx. Flow (gpm) | Notes |
|---|---|---|
| 25 | 8.5 | Light duty gearbox/motor set |
| 50 | 17.0 | Typical small crusher subassembly |
| 100 | 34.0 | Mid-size mill bearing group |
| 150 | 51.0 | High load transfer point |
| 250 | 85.0 | Large crusher/mill cooling loop |
Recommended Pattern & Pressure by Task
Select by target, distance, and desired impact; confirm against site constraints.
| Cooling Task | Typical Pattern | Pressure Range (psi) | Standoff (ft) | Comments |
|---|---|---|---|---|
| Equipment cooling (bearings/gearboxes) | Flat fan / solid stream | 80–200 | 1–3 | Higher impact; aim for direct impingement. |
| Conveyor/material cooling | Full cone | 40–120 | 2–4 | Wide, even coverage over belt width. |
| Chute/transfer cooling | Full cone / flat fan | 60–150 | 2–5 | Balance coverage with drift control. |
| Dust + heat combined | Fine mist / fog | 20–60 | 2–8 | Small droplets for dust capture; watch wind. |
Droplet Size Guidance (SMD)
Sauter Mean Diameter (SMD) ranges; smaller = faster heat transfer but more drift potential.
| Use Case | Typical SMD (μm) | Notes |
|---|---|---|
| Equipment cooling (impact) | 300–800 | Larger droplets for momentum/impingement; less drift. |
| Material/belt cooling | 400–1000 | Penetration with limited overspray. |
| Dust + light cooling | 50–200 | High surface area; monitor drift/evaporation. |
Coverage Diameter from Angle & Distance
D ≈ 2 × L × tan(θ/2). Use to check overlap for even cooling across a belt or target.
| Spray Angle (°) | Standoff L (ft) | Coverage D (ft) | Notes |
|---|---|---|---|
| 60 | 1 | 1.15 | Spot cooling at close range |
| 60 | 3 | 3.46 | Multiple-nozzle overlap likely required |
| 80 | 2 | 3.03 | Wider coverage; watch drift |
| 80 | 4 | 6.07 | For wide belts/transfer points |
| 90 | 3 | 6.00 | Very wide; ensure containment |
Water Use Planner by Target Temperature Drop
Approximate flow per 100 kW heat removed for different water ΔT targets (larger ΔT = less water).
| Target ΔT (°F) | Flow per 100 kW (gpm) | Comment |
|---|---|---|
| 10 | 68.2 | Low ΔT → highest water use, best thermal margin |
| 15 | 45.5 | Balanced for many open systems |
| 20 | 34.1 | Common planning baseline |
| 25 | 27.3 | Lower water; ensure outlet temp limits |
| 30 | 22.7 | Conservative water use; check materials |
Calculation basis (illustrative): Q[gpm] ≈ (Heat[kW] × 3412 BTU/h·kW) / (500 × ΔT°F).
