Fogging trucks are essential pest control equipment in sand and gravel production sites, effectively eliminating mosquitoes, flies, and other insects that interfere with operations. These vehicles integrate high-pressure spray systems with 200-400L tanks, achieving 50-100μm droplet size for optimal dispersion. Common models feature 25-50HP diesel engines and 360° rotating nozzles.
A complete aggregate processing line typically includes:
1. Primary Jaw Crusher (90-450t/h capacity)
2. Secondary Cone Crusher (50-300t/h)
3. Tertiary Impact Crusher (60-500t/h)
4. VSI Sand Maker (30-400t/h)
5. Vibrating Screens (2-4 deck configurations)
Key parameters for VSI crushers:
| Model | Max Feed Size | Capacity | Power |
|——-|————–|———-|——-|
| VSI800 | 45mm | 60-140t/h | 110kW |
| VSI1140 | 50mm | 120-220t/h | 220kW |
Location: Johor Bahru
Configuration:
– PE750×1060 Jaw Crusher
– HST315 Cone Crusher
– VSI1140 Sand Maker
Output: 200tph manufactured sand (0-5mm)
Dust control: Integrated fogging system with 8 spraying points
Q: How often should crusher wear parts be replaced?
A: Jaw plates last 3-6 months; cone mantles 6-12 months depending on material hardness.
Q: What’s the optimal moisture content for screening?
A: Below 3% for dry screening; up to 8% for wet processes.
Q: Can fogging systems operate in rain?
A: Yes, but efficiency reduces by approximately 40% during precipitation.
Maintenance Tip: Always check hydraulic oil temperature stays below 65°C in crushers to prevent component damage.
