India’s chrome ore beneficiation relies heavily on efficient crushing and sand-making lines to produce high-quality aggregates. Below is a breakdown of core equipment and practices.
1. Jaw Crusher (Primary Crushing)
– Model: JC1200
– Feed Size: ≤1000mm
– Capacity: 200-400 TPH
– Power: 160 kW
2. Cone Crusher (Secondary Crushing)
– Model: HPC300
– Max Feed: 350mm
– Output Size: 10-50mm (adjustable)
– Capacity: 150-300 TPH
3. Vertical Shaft Impact Crusher (Sand Making)
– Model: VSI1140
– Input Size: ≤50mm
– Output: 0-5mm (artificial sand)
– Capacity: 100-200 TPH
A typical setup includes:
– Primary Crushing: Jaw crusher → Vibrating screen (pre-screening)
– Secondary Crushing: Cone crusher → Sand maker → Screening (grading)
– Washing: Spiral classifier or sand washer (for high-grade aggregates)
Q1: What’s the ideal moisture content for chrome ore sand?
A: Below 3% to ensure smooth screening and storage.
Q2: How to reduce dust in crushing lines?
A: Use dust suppression systems (water spray + bag filters).
Project: Odisha Chrome Beneficiation Plant, India (2023)
– Capacity: 500 TPD (tons per day)
– Equipment: JC1200 + HPC300 + VSI1140 + Sand Washer
– Output: 0-5mm sand (60%), 5-20mm aggregate (30%)
