The Comprehensive Guide to Iron Ore Loading Equipment and Crushing/Sand-Making Systems in Aggregate Industry
Industry Background
The global demand for iron ore and construction aggregates continues to drive innovation in crushing and sand-making technologies. As infrastructure projects expand, the need for efficient material handling—from extraction to loading—has become critical. The iron ore and aggregate sectors share synergies in equipment design, particularly in high-capacity crushing, screening, and material transfer systems.
Core Equipment for Iron Ore Loading & Processing
1. Primary Crushing Stations
– Jaw Crushers: Heavy-duty models (e.g., C6X Series) handle iron ore’s abrasiveness with 1,500 mm feed openings.
– Gyratory Crushers: Preferred for mines with >5,000 TPH capacity, offering reduced downtime via hydraulic adjustment.
2. Secondary/Tertiary Crushing
– Cone Crushers: Multi-cylinder hydraulic designs (like HPT Series) achieve 10–40 mm output for pellet feed.
– Impact Crushers: Vertical shaft impactors (VSI6X) produce cubical aggregates for high-grade concrete.
3. Screening & Transfer
– Banana Screens: High-efficiency 3-deck designs segregate sizes at 800–1,200 tph.
– Stacker Conveyors: Radial telescopic models load vessels at 5,000–20,000 tph rates with automated slew systems.
4. Loading Terminals
– Ship Loaders: Boom-type loaders with 10,000 tph capacity and dust suppression nozzles.
– Railcar Dumpers: Rotary systems unload 100-car unit trains in <2 hours.

FAQ Section
Q1: How to minimize iron ore degradation during loading?
A: Use cascading chute designs with rubber lining to control freefall height below 3 meters.
Q2: What’s the optimal crusher ratio for hematite vs. magnetite?
A: Magnetite’s higher hardness requires HPGR (High-Pressure Grinding Rolls) after secondary crushing for energy efficiency.
Q3: Can aggregate crushers process iron ore?
A: Only with tungsten carbide liners and reduced rotor speeds (≤35 m/s) to handle Fe content >60%.
