For efficient coal processing in India’s mining and power sectors, mobile coal screening machines offer flexibility and high throughput. These units typically feature vibrating screens with 2-3 deck configurations, handling capacities of 50–400 TPH, and mesh sizes from 5mm to 100mm. Popular models include track-mounted units with diesel generators (e.g., 150 kVA) for remote operations.
| Model | Screen Size (m) | Capacity (TPH) | Power (kW) |
|---|---|---|---|
| MS-903 | 3.0×1.8 | 80–120 | 22 |
| MS-1202 | 4.8×1.8 | 200–300 | 45 |
| MS-1503 | 6.0×1.8 | 350–400 | 75 |
Mobile screeners often pair with jaw crushers (e.g., 200×300 mm feed size) or impact crushers for pre-screening coal. A typical setup includes:
1. Primary crushing → Screening → Stockpiling
2. Direct feeding to conveyor belts for washed coal
Q1: What’s the lifespan of screen mesh?
A: Polyurethane meshes last ~6 months in abrasive coal; steel wire meshes require replacement every 3–4 months.
Q2: Can these units handle wet coal?
A: Yes, models with heated screen decks or high-frequency vibration prevent clogging at up to 15% moisture content.
A 250 TPH mobile screener (MS-1202) was deployed for lignite screening, achieving 98% efficiency with 25mm–50mm output sizes. The system reduced fuel ash content by 12% through multi-stage screening
