Maintenance cycle Gold factory adaptation plan
Typical Configuration:nits in parallel Processing capacity 30m³/h Equipped with 1.5m³ nitrogen buffer tank Process indicators:
The adsorption rate of gold-loaded carbon increased to 99.8%
Carbon content of tailings slurry <0.01g/m³ pecial maintenance tips
1.Weekly inspection:
Explosion-proof surface fastening bolt torque (42±5N·m) Nitrogen pipeline air tightness test
2.Annual overhaul:
Replace all explosion-proof junction box seals
Screen wear layer thickness detection (<3mm must be replaced)
(Note: Specific cyanidation process parameters need to be provided to optimize the screen inclination and water pressure)
