Gold placer recovery plants require efficient crushing and sand-making equipment to process raw materials into high-quality aggregates. A well-designed production line ensures optimal recovery rates and minimizes waste.
1. Jaw Crusher (Primary Crushing)
– Model: PE-600×900
– Feed Size: ≤500mm
– Capacity: 50-160 t/h
– Power: 55-75 kW
2. Cone Crusher (Secondary Crushing)
– Model: CS160
– Max Feed Size: 240mm
– Capacity: 110-320 t/h
– Power: 160 kW
3. Sand Maker (VSI Crusher)
– Model: VSI-1140
– Output Size: 0-5mm (adjustable)
– Capacity: 100-260 t/h
– Power: 250 kW
4. Vibrating Screen
– Model: 3YK2460
– Screen Layers: 3
– Capacity: 80-150 t/h
Raw placer ore → Jaw Crusher (coarse crushing) → Cone Crusher (fine crushing) → Sand Maker (shaping) → Vibrating Screen (grading) → Final aggregates for gold recovery.
Q1: What is the ideal feed size for a jaw crusher in placer processing?
A1: ≤500mm to ensure efficient primary crushing.
Q2: How to adjust the output size of the sand maker?
A2: Modify the rotor speed or replace the crushing chamber liners.
Q3: What maintenance is required for cone crushers?
A3: Regular lubrication and inspection of wear parts like mantles and concaves.
A gold placer plant in Alaska adopted this line, achieving a daily output of 1,200 tons of high-quality sand for sluice box separation. The final recovery rate improved by 15% compared to traditional methods.
