In November 2012, the global price of copra (dried coconut kernel) averaged $800–$1,000 per ton, influenced by fluctuating demand in the edible oil and biofuel sectors. Regional variations occurred due to supply chain disruptions and seasonal production cycles in major exporters like Indonesia and the Philippines.
Modern sand-making plants integrate high-efficiency crushers, screens, and classifiers to transform raw materials (granite, basalt, or river pebbles) into graded aggregates. A typical configuration includes:
– Primary Jaw Crusher: PE600×900 (Feed size: ≤500mm; Output: 50–160t/h)
– Secondary Cone Crusher: HPT300 (Max feed: 240mm; Capacity: 120–400t/h)
– Tertiary VSI Crusher: B-9100SE (Throughput: 200–400t/h; Product shape: Cubical)
– Vibrating Screen: 3YK3070 (Deck layers: 3; Screening efficiency: ≥90%)
| Equipment | Model | Power (kW) | Output Size (mm) |
|---|---|---|---|
| Jaw Crusher | PE750×1060 | 110 | 80–180 |
| Cone Crusher | HST250 | 315 | 19–38 |
| Sand Maker | S8-1145 | 440 | 0–5 (adjustable) |
Q1: How to reduce dust in sand production?
*A:* Install wet scrubbers or pulse bag filters (+99% efficiency).
Q2: Optimal moisture content for screening?
*A:* Keep below 3% to prevent clogging.
