Drawing inspiration from Michael Morpurgo’s “The Marble Crusher,” modern aggregate plants transform raw stone into premium construction materials. This article explores a compact marble crushing and sand-making line tailored for medium-hardness minerals (Mohs 3-5).
The 150TPH production line features:
1. Vibrating Feeder: GZD-960×3800 (15kW)
2. Jaw Crusher: PE-600×900 (75kW, feed size ≤500mm)
3. Cone Crusher: HPT300 (220kW, discharge 20-50mm)
4. VSI Sand Maker: VSI1140 (250kW, sand yield 40%)

| Model | Capacity(t/h) | Power(kW) | Output Size(mm) |
|---|---|---|---|
| PE-400×600 | 15-60 | 30 | 40-100 |
| PE-600×900 | 50-160 | 75 | 65-160 |
| HPT200 | 90-250 | 160 | 10-30 |
The system incorporates:
– Water spray dust suppression (-90% particulate)
– Rubber conveyor belts (58dB noise reduction)
– Closed-circuit screening (95% material utilization)

Q: How to prevent marble dust accumulation?
A: Install pulse jet bag filters with ≥99% efficiency.
Q: Optimal crusher wear part replacement cycle?
A: Manganese steel jaws last 800-1,200 hours depending on SiO₂ content.
