The Assam government’s stone crusher policy mandates strict compliance with environmental norms, requiring dust suppression systems and noise control measures. Modern crushing plants in the region now prioritize multi-stage processing with jaw crushers (e.g., 90–160 kW motor power), cone crushers (like 75–315 kW models), and VSI sand makers for cubical aggregates.
A typical setup includes:
– Primary Jaw Crusher: Feed size ≤1,200 mm, capacity 50–800 TPH
– Secondary Cone Crusher: Closed-side setting 20–50 mm, output gradation adjustable
– Tertiary VSI Crusher: Produces 0–5mm sand with ≤3% flakiness index
– Vibrating Screens: 3–4 deck configurations, screening efficiency ≥90%
| Equipment | Model Example | Power (kW) | Max Feed Size (mm) | Output Range (mm) |
|———–|————–|————|——————-|——————|
| Jaw Crusher | JC110 | 110 | 850 | 100–250 |
| Cone Crusher | HPC200 | 200 | 240 | 10–45 |
| VSI Crusher | VSI1140 | 250×2 | 50 | 0–8 (sand) |
Q: How to reduce dust in Assam’s humid climate?
A: Use wet suppression systems with 5–10L/min water spray nozzles + enclosed conveyor belts.

Q: What’s the ideal production layout for granite?
A: Two-stage crushing (jaw + cone) + sand shaping (VSI), achieving 35% sand yield.
