NABARD (National Bank for Agriculture and Rural Development) offers subsidies for stone crusher units under its Rural Infrastructure Development Fund (RIDF). Eligible projects include setting up crushing plants for producing aggregates, sand, and gravel. Subsidies typically cover 25-40% of machinery costs, with priority given to MSMEs and rural entrepreneurs.
Modern stone crusher plants integrate primary jaw crushers, secondary cone crushers, and tertiary VSI sand makers. Key equipment specifications:
| Equipment | Model Example | Capacity (TPH) | Power (kW) | Output Size (mm) |
|—————–|—————|—————-|————|——————|
| Jaw Crusher | PE-600×900 | 50-120 | 75 | 60-150 |
| Cone Crusher | HPT300 | 70-180 | 220 | 10-30 |
| VSI Crusher | B-9100SE | 100-260 | 250 | 0-5 (sand) |
1. Primary Crushing: Raw granite/basalt fed into jaw crusher.
2. Secondary Crushing: Cone crusher refines material to ≤30mm.
3. Sand Making: VSI crusher produces cubical sand (0-5mm).
4. Screening: Vibrating screens separate aggregates into 5-10mm, 10-20mm, etc.
Q: What’s the minimum land requirement?
A: ~1 acre for a 200TPH plant including stockpile areas.
Q: Can NABARD subsidy be combined with state schemes?
A: Yes, in states like Rajasthan or Karnataka.
A subsidized unit in Ahmedabad processes 250TPH basalt using:
– Primary: JC110 jaw crusher (160kW)
– Secondary: HST315 cone crusher (315kW)
– Output: 0-5mm sand (40%), 10-20mm aggregate (35%)
