Molino de bolas para mineral de plomo-zinc
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.
Adaptable to South American Mining Conditions
Designed to operate reliably in high-altitude Andean mines (Peru/Chile) and arid northern Mexico conditions, with dust-proof seals, temperature-resistant bearings, and corrosion-resistant coatings.
