Ballast feeding equipment is a critical component in aggregate production lines, ensuring efficient material transfer to crushers, screens, and sand-making machines. High-performance feeders, such as vibrating grizzly feeders or apron feeders, optimize raw material flow while reducing wear on downstream equipment. Key manufacturers focus on durability, adjustable feed rates (e.g., 50–1,500 TPH), and integration with automation systems for seamless operation.
A typical crushing and sand-making line includes:
1. Primary Crusher: Jaw crusher (e.g., feed size ≤1,200 mm, capacity 50–800 TPH).
2. Secondary Crusher: Cone/impact crusher for finer crushing (output size ≤40 mm).
3. Sand Maker: VSI crusher producing 0–5 mm sand with high cubicity.
4. Screening System: Multi-deck screens (e.g., 3-layer, 15–30° inclination) for precise grading.
| Equipment | Model Example | Capacity (TPH) | Power (kW) | Output Size (mm) |
|——————–|—————|—————-|————|——————|
| Vibrating Feeder | ZSW-600×130 | 100–400 | 22 | ≤800 |
| Jaw Crusher | PE-1200×1500 | 500–800 | 160 | ≤300 |
| VSI Sand Maker | VSI-1140 | 200–350 | 250 | 0–5 |
Q: How to reduce dust in the production line?
A: Install dust collectors (e.g., pulse bag filters) at transfer points and use water spray systems.
Q: What’s the lifespan of wear parts in a VSI crusher?
A: Typically 100–200 hours for rotor tips; material hardness affects longevity.
A granite processing plant in Malaysia deployed a 500 TPH line with ZSW feeders, jaw/cone crushers, and a VSI sand maker. The output achieved 45% high-quality sand (0–
