1.Working Principle
The Huashengming double-roll crusher crushes materials by applying continuous compressive force through two counter-rotating rolls. This relatively “gentle” crushing method offers key advantages for lead-zinc ore processing.
2. Advantages
Precise particle size control effectively reduces over-crushing
Lead-zinc ores are predominantly sulfide minerals. Excessive impact crushing generates significant powder, leading to metal loss during beneficiation. The slow compression of double-roll crushers effectively minimizes the production of excessively fine powder, ensuring uniform particle size distribution in the final product. This is crucial for enhancing mineral recovery rates.
Specialized Wear-Resistant and Corrosion-Resistant Design
Addressing the corrosive nature of sulfur-containing lead-zinc ores, Huashengming’s double-roll crushers feature roll surfaces made of high-chromium alloy (hardness up to HRC 60-62) with anti-corrosion coating. This design extends roll surface lifespan to 6-8 months under harsh operating conditions.
Energy-Efficient Operation Reduces Overall Costs
The equipment operates with low energy consumption per unit, reportedly reducing energy use by approximately 30% compared to impact sand makers. Additionally, the finished sand exhibits high cubic content and continuous gradation, facilitating mineral processing while also serving as construction sand or backfill mining aggregate—enabling comprehensive resource utilization.
