Assam Stone Crusher Policy and Its Impact on Aggregate Production

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.

Key Equipment for High-Efficiency Crushing Lines

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%

Product Parameters Table

| 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) |

FAQ

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.
