India’s coal-fired power plants and heavy industries rely on high-performance coal pulverizers to achieve efficient combustion. Leading suppliers like L&T, BHEL, and Thermax provide robust vertical spindle mills and bowl mills capable of grinding coal to 70-90% below 75 microns.
A complete sand and aggregate production line typically includes:
1. Primary Crusher: Jaw crusher (e.g., 400×600mm feed size, 50-100tph capacity)
2. Secondary Crusher: Cone crusher (e.g., GP300, 200-300tph output)
3. Tertiary Crusher: VSI crusher for shaping (e.g., 50-500tph, ≤5mm final product)
4. Screening: Multi-deck vibratory screens (e.g., 3YK3070, 100-150tph)
| Model | Max Feed Size | Capacity (tph) | Motor Power (kW) |
|---|---|---|---|
| VSI-7611 | 35mm | 60-180 | 110-150 |
| VSI-1140 | 50mm | 120-380 | 250-315 |
| HVI-0815 | 45mm | 150-300 | 264-320 |
Q1: What’s the lifespan of a VSI crusher rotor?
A: Typically 1,200–2,000 hours depending on abrasiveness; tungsten carbide tips extend durability.
Q2: How to reduce dust in aggregate plants?
A: Use wet suppression systems or bag filters with ≥99% efficiency.
