1. Crushing system configuration

Two-stage crushing process

Primary crushing: PE250×400 jaw crusher (feed size ≤210mm, discharge size ≤60mm)

Secondary crushing: PGY800×600 roller crusher (discharge size ≤15mm)

Supporting equipment: GZD650×2300 vibrating feeder + TD75 belt conveyor system

Key technical parameters

Processing capacity: 3-5t/h (adjustable)

Power configuration: total installed capacity ≤45kW

Dust removal system: pulse bag dust collector (handling air volume 3000m³/h)

2. Flotation system design

Core equipment selection

Flotation machine: XJK-0.35 mechanical stirring flotation machine (4 tanks in series)

Reagent preparation: YJB-500 reagent mixing barrel (with metering pump)

Dehydration equipment: GNZ-3 high-efficiency concentrator + 750×750 plate and frame filter press

Process flow

Grinding (-200 mesh accounts for 65%) → Roughing (butyl xanthate 60g/t) → Scavenging (2 times) → Concentration (3 times)

→ Concentration and dehydration (final copper concentrate water content ≤18%)

Operation indicators

Ore grade: 0.8-1.2%Cu

Concentrate grade: ≥18%Cu

Recovery rate: 85-90%

Power consumption: ≤35kWh/t

3. Environmental protection and safety measures

Fully enclosed design of crushing workshop + sound insulation cotton (noise ≤75dB)

Tailings water circulation system (reuse rate ≥85%)

Flotation reagent automatic filling system (error ±2%)
