Molino de barras para arena en Perú

The Lead-Zinc Ore Ball Mill is purpose-built for high-efficiency fine grinding of lead-zinc ores in beneficiation plants across South America. 

Designed to process both primary and secondary lead-zinc ores, it delivers consistent particle size distribution, maximizing flotation recovery rates for lead and zinc concentrates. 

With heavy-duty construction optimized for the harsh, high-altitude and arid mining environments of Peru, Chile, and Mexico, this mill is a reliable workhorse for your lead-zinc processing line.

Core Technical Highlights

High-Efficiency Fine Grinding for Flotation

Advanced grinding media grading and optimized liner design ensure uniform fine grinding, producing the ideal particle size for lead-zinc flotation circuits. This directly improves concentrate grade and recovery rates, reducing reagent consumption and tailings loss.

Heavy-Duty & Wear-Resistant Build

Thick steel shell combined with high-chrome alloy liners withstands the abrasion of hard lead-zinc ores. Reinforced main bearings and a high-torque drive system ensure stable operation under continuous, heavy loads in remote mining sites.

Low Energy Consumption & High Capacity

High-efficiency girth gear and pinion drive reduces power consumption by 15-20% compared to standard mills. The optimized internal flow design boosts throughput, making it ideal for large-scale lead-zinc mining operations.

Customizable for Wet/Dry & Continuous Operation

Available in overflow and grate discharge configurations:

-- Overflow type: Ideal for continuous wet grinding in large-scale lead-zinc mines.

-- Grate discharge type: Suitable for high-capacity coarse grinding stages.

Internal Structure (Key Components)

Mill Shell: Thick steel plate welded construction, stress-relieved for structural stability under heavy loads.
