Sand Mining Challenges in West Bengal: Sustainable Solutions

West Bengal faces severe environmental and infrastructural issues due to uncontrolled sand mining. To address this, modern crushing-screening plants offer eco-friendly alternatives by processing hard rocks into high-quality aggregates.

Core Equipment for Sand-Gravel Production

A typical 200TPH plant includes:
1. Primary Jaw Crusher (PE-600×900) – 75kW motor, ≤480mm feed size
2. Secondary Cone Crusher (HPT300) – Hydraulic adjustment, 220kW power
3. Tertiary VSI Crusher (B-9100SE) – Rock-on-rock design, 45-165tph capacity
4. Vibrating Screens (3YK3070) – Triple-deck, 22kW power

Key Parameters Comparison

Model Capacity(tph) Power(kW) Output Size(mm)
PE-600×900 50-160 75 65-160
HPT300 120-250 220 5-60
B-9100SE 45-165 250 0-5 (sand)

Frequently Asked Questions

Q: What’s the lifespan of wear parts?
A: Jaw plates last ~6 months, cone mantles ~4 months under normal conditions.

Q: Can it process river gravel?
A: Yes, but requires pre-screening to remove silt.

Q: Minimum required space?
A: ~50m×30m for a complete 200TPH plant.

Sundarbans Rehabilitation Project Case

A 150TPH plant installed in 2021 produces:
– M-Sand (0-4.75mm) for concrete
– 10-20mm aggregate for road base
Reducing illegal river mining by 40% in the region. The system features water recycling
