A robust material handling system is critical for transporting slag, clinker, or other furnace byproducts to crushers in sand/aggregate production lines. This process directly impacts crushing efficiency and final product quality.
The typical system includes:
1. Vibrating Feeders (Capacity: 50-800t/h)
2. Belt Conveyors (Width: 500-1400mm)
3. Heavy-duty Impact Crushers (Feed size: ≤800mm, Output: 50-500t/h)
4. Dust Suppression Units (Water consumption: 0.5-3m³/h)
| Equipment | Model Example | Key Parameters |
|---|---|---|
| Impact Crusher | PF-1520 | Rotor Φ1500×2000mm, Power 315-400kW |
| Vibrating Feeder | GZD-1500×6000 | Capacity 400-600t/h, Vibration force 25kN |
| Conveyor Belt | B1400 | Belt width 1400mm, Speed 1.6-2.5m/s |
• Pre-screening before crushing reduces wear
• Magnetic separation for ferrous materials
• Temperature monitoring for hot materials (>200°C requires special belts)
Q: How to handle sticky materials from furnaces?
A: Install scrapers on conveyor belts and use heated chutes.
Q: Recommended crusher for high-temperature slag?
A: Water-cooled rotor impact crushers with Mn-steel liners.
• Material: Blast furnace slag at 180-250°C
• Solution:
– Air-cooling tunnel + water spray system
– Dual-stage crushing (Jaw + Impact crusher)
• Result: Achieved 250tph production of 0-5mm sand
