Extracting gold from ore requires efficient crushing and grinding equipment to liberate gold particles. A well-designed sand production line ensures optimal particle size for further processing. Below is a breakdown of key equipment and processes.
1. Jaw Crusher (Primary Crushing)
– Model: JC1200
– Feed Size: ≤1000mm
– Capacity: 200-500 t/h
– Power: 160 kW
2. Cone Crusher (Secondary Crushing)
– Model: HPC300
– Max Feed Size: 240mm
– Capacity: 150-400 t/h
– Power: 220 kW
3. Vertical Shaft Impact Crusher (Sand Making)
– Model: VSI-1140
– Feed Size: ≤50mm
– Capacity: 100-300 t/h
– Power: 250 kW
4. Vibrating Screen (Particle Classification)
– Model: 3YK3070
– Screen Layers: 3
– Capacity: 80-500 t/h
1. Primary crushing reduces large ore chunks to ≤200mm.
2. Secondary crushing further refines material to ≤50mm.
3. Sand making produces fine particles (0-5mm) for gold extraction.
4. Screening separates oversize material for recirculation.
Q1: What’s the ideal feed size for gold ore crushers?
A1: ≤1000mm for jaw crushers; ≤240mm for cone crushers.
Q2: How to improve sand yield in gold ore processing?
A2: Optimize VSI crusher speed and feed rate, ensuring proper moisture content (<5%).
Q3: Can this line process other ores?
A3: Yes, it suits iron, copper, and quartz with minor adjustments.
