Ores for gold extraction and processing crusher Also known as a double-roll crusher (including double-tooth roll crushers), it is fully capable of serving as the core crushing
equipment for gold mining and processing, demonstrating significant advantages particularly in the medium and fine crushing stages.
ores for gold extraction and processing crusher
1. Technical Suitability: Feasibility of Gold Ore Crushing
Hardness and Material Compatibility
The double-roll crusher can process gold ores with compressive strength ≤250MPa, covering quartz vein-type gold deposits (typically 150-200MPa hardness) and
certain superhard rock types. Roll surfaces utilize high-chromium manganese steel or wear-resistant alloy (hardness HRC≥60), delivering over 2 years of service
life and significantly reducing maintenance costs.
Precision Particle Size Control
Hydraulic or mechanical roll gap adjustment (±1mm precision) enables stable output particle sizes between 1-5mm, meeting optimal sizing requirements for
leaching/flotation processes. Over-crushing rate <10% minimizes loss of fine gold particles.
Adaptability to Wet and Sticky Materials
The toothed roller design handles gold ore with high clay content or moisture content ≤35%, using shear force to strip viscous minerals and prevent jamming
(traditional jaw/cone crushers are prone to clogging).
2. Core Advantages: Competitive Edge in Gold Ore Crushing Applications
High Efficiency & Energy Savings
Layer compression crushing principle saves 30%-45% electricity compared to impact crushers, with power consumption per ton of ore at only 0.8-1.2 RMB;
Dual-motor independent drive mode allows flexible switching between single/dual-unit operation, further reducing energy consumption.
Overload Protection & Stability
Hydraulic springs automatically retract upon encountering hard objects (e.g., iron blocks), safeguarding core components;
Dual-safety system featuring hydraulic couplers + sensors ensures a failure rate **<1%, guaranteeing continuous production.
Environmental Compliance
Enclosed structure + pulse dust collection system keeps dust emissions **<10mg/m³ and noise ≤75dB(A)**, meeting green mining standards.
Versatility and Flexibility
Interchangeable tooth profiles adapt to various gold ore types (e.g., oxidized, sulfide);
Tiered dual-tooth roller models integrate crushing and screening functions, streamlining process flows.
