The future of stone quarrying near Bhavnagar hinges on efficient crushing and sand-making technologies. With growing demand for construction aggregates, modern plants prioritize high-output, low-wear equipment to process basalt, limestone, or granite.
1. Primary Jaw Crusher (e.g., JC5460)
– Feed opening: 1400×1100mm
– Capacity: 800–1200 TPH
– Power: 400 kW
2. Secondary Cone Crusher (e.g., HPT500)
– Max feed size: 350mm
– Output: 300–600 TPH
– Hydraulic adjustment
3. Tertiary Impact Crusher (e.g., VSI6X1263)
– Rotor speed: 1200–1800 rpm
– Sand yield: Up to 70%
4. Vibrating Screens (3-4 deck)
– Screening efficiency: ≥90%
Raw material → Primary crushing → Secondary crushing → Screening → Sand making → Grading → Stockpiling. Optional sand washing modules ensure silt control per IS 383 standards.
Q1: What’s the lifespan of wear parts in basalt crushing?
*A:* Jaw plates last ~6 months; cone mantles ~4 months with proper maintenance.
Q2: Can the plant produce railway ballast?
*A:* Yes, via tertiary screening (45–65mm gradation).
A Bhavnagar-based quarry upgraded to a 500 TPH plant in 2023, achieving:
– Sand replacement ratio: 1:1.15 (vs. natural sand)
– Power consumption: ≤25 kWh/tonne
