Australia’s mining and construction sectors frequently rely on crushing equipment auctions to source cost-effective machinery for sand and aggregate production. This article explores core equipment types, technical parameters, and real-world applications for optimized crushing-screening plants.
1. Primary Jaw Crushers
– Model Example: J1480 (Feed opening: 1,400x800mm, Capacity: 700 tph)
– Function: Coarse crushing of hard rock (granite, basalt).
2. Secondary Cone Crushers
– Model Example: C1540 (Max feed size: 160mm, CSS range: 10-45mm)
– Ideal for producing cubical aggregates for concrete/asphalt.
3. Tertiary Impact Crushers
– Model Example: I140 (Rotor diameter: 1,270mm, Output: 0-20mm sand)
– Used for manufactured sand (M-sand) production.
4. Screening Systems
– Multi-deck vibratory screens (e.g., 3-deck 20×5 ft, throughput 500 tph).
| Equipment | Key Parameter | Typical Value |
|—————–|—————————-|————————|
| Jaw Crusher | Feed Opening | 1,200x750mm |
| Cone Crusher | Closed Side Setting (CSS) | 8-38mm |
| Impact Crusher | Rotor Speed | 600-800 rpm |
| Screen | Deck Area | 10m² per deck |
Q1: How to assess used crushers at auctions?
A: Inspect wear parts (liners, bearings), check maintenance logs, and verify hydraulic system integrity.
Q2: What’s the ideal setup for a 200tph granite plant?
A: Jaw crusher (primary) + cone crusher (secondary) + 3-deck screen.
