Huashengming rock crusher for gold primarily employs a double-roll design (twin-roll crusher), optimized for crushing medium-to-high hardness rocks like gold ore. Combining wear-resistant technology with a hydraulic adjustment system, it enhances mining operation efficiency.

1. Working Principle and Structural Features
Double-roll compression crushing
Two counter-rotating rollers crush materials by squeezing and grinding them within the roll gap. Hydraulic or spring adjustment controls the roll gap (1-50mm) to regulate output particle size.
Overload protection: Automatic roll retraction upon encountering hard objects (e.g., unbroken large ore chunks) prevents equipment damage.
Wear-Resistant Core Technology
Roll shells utilize high-chromium manganese steel + rare metal alloy (patented technology), enhancing wear resistance by 50% with a service life ≥2 years, reducing maintenance downtime frequency.
2. Model Parameters and Capacity Grading
Huashengming gold ore crushers are categorized into three capacity tiers, covering small-scale prospecting to large-scale mining operations:
| Model | ?Roll Diameter × Roll Length (mm) | Feed Size (mm) | Capacity (t/h) | ?Motor Power (kW) | ?Applications |
|---|---|---|---|---|---|
| Small (e.g., 2PGT400×400) | φ400×400 | ≤25 | 5-12 | 15×2 | Small-scale gold mining, mobile exploration operations |
| Medium (e.g., 2PGT400×400) | φ800×600 | ≤40 | 12-50 | 45×2 | Medium-sized mines, fixed production lines |
| Large (e.g., 2PGT400×400) | φ2000×1200 | ≤120 | 300-400 | 160×2 | Large-scale gold mining, intensive aggregate production |
Note: Model prefix “2PGT” denotes spring adjustment, while “2PGY” indicates hydraulic adjustment. The latter supports intelligent gap adjustment and carries a 30%-50% higher price.

3. Advantages in Gold Ore Crushing Applications
Energy Efficiency
Dual-motor drive reduces energy consumption by 20% compared to cone crushers at equivalent capacity. Over-crushing rate <8% preserves ore particle integrity, facilitating subsequent leaching and gold extraction.
Wet Material Adaptability
Screenless design prevents clogging in wet ores, supporting crushing of gold ores with ≤15% clay content (e.g., oxidized ores).
Mobility and Power Adaptability
Compact models (e.g., 2PGT610×400) support dual diesel/electric power, ideal for grid-unconnected mining areas. Modular construction enables rapid disassembly, relocation, and transportation.
