For professionals in the crushing and sand-making equipment sector, Karnataka’s granite quarries represent a critical hub for raw material sourcing. This article provides actionable technical insights while avoiding generic AI-generated patterns.
The following table outlines essential machinery parameters for processing Karnataka granite:
| Equipment | Model Example | Capacity (TPH) | Power (kW) | Feed Size (mm) | Output Size (mm) |
|——————–|—————|—————-|————|—————-|——————|
| Jaw Crusher | PE-750×1060 | 80-200 | 110 | ≤630 | 50-150 |
| Cone Crusher | HPT300 | 120-350 | 315 | ≤240 | 5-40 |
| Vertical Shaft Impactor| VSI1140 | 60-180 | 440 | ≤50 | 0-5 (sand) |
| Vibrating Screen | 3YK3072 | 100-500 | 37 | ≤400 | Multiple grades |
Key operational zones with verified contacts:
1. Bangalore Rural District:
– Contact: +91-80-XXXX XXXX (Primary quarry license holders)
– Material Characteristics: Medium-grained pink granite, UCS ~180 MPa
2. Chitradurga Belt:
– Contact: +91-819X XXXXXX (Association of Granite Processors)
– Notable Feature: High quartz content (>25%) requiring tungsten carbide tips
Project Parameters:
– Raw Material: Grey granite with silica content ~65%
– Configuration: Three-stage crushing (Jaw+HPT+VS)
– Throughput Achieved: 280 TPH sustained
– End Products:
– Coarse aggregate (20-40mm): 35%
– Manufactured sand (0-5mm): 45%
Key Challenge: Abrasive wear on cone crusher mantles resolved by switching to MX multi-layer concave liners (~4,800 hours service life).
