Karnataka’s stone crushing industry operates under strict environmental and zoning rules (KSPCB guidelines). Key compliance points include:
– Minimum 2-acre land requirement for crushers
– 500m buffer zone from residential areas
– Mandatory pollution control systems
A typical 200TPH granite processing line includes:
| Equipment | Model Example | Key Parameters |
|———–|————–|—————-|
| Jaw Crusher | PE750×1060 | Feed size: 630mm, Capacity: 110-320t/h |
| Cone Crusher | HPT300 | Max input: 240mm, Output: 19-38mm |
| VSI Crusher | VSI1140 | Throughput: 180-380t/h, Product shape index ≥90% |
| Vibrating Screen | 3YK3070 | Screening efficiency ≥90% |
Q1: What’s the production cost per ton?
A: Typically ₹120-180/ton including power, wear parts, and labor.
Q2: How to reduce dust emissions?
A: Use wet suppression systems + bag filters (99% efficiency required).
Material: Black granite
Output: 250tph (20-40mm aggregate + M-sand)
Key Solution: 3-stage crushing with jaw+cone+VSI configuration reduced flakiness content to <12%. Dust control achieved through mist cannons and covered conveyors. ROI achieved in 18 months.
