Стержневая мельница для песка в Перу

Шаровая мельница для свинцово-цинковой руды предназначена для высокоэффективного тонкого помола на обогатительных фабриках 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.

Liner Plates: High-chrome alloy liners with optimized lifter geometry to enhance grinding efficiency and media movement.

Main Bearing Assembly: Large, heavy-duty sliding bearings with forced lubrication for low friction and high load capacity.

Drive System: Girth gear + pinion drive with high-precision machining, paired with a low-speed high-torque motor.

Feed & Discharge Heads: Cast steel heads with wear-resistant liners, designed for smooth material flow and minimal wear.

Grinding Media: Custom-graded high-carbon steel balls, optimized for your specific lead-zinc ore hardness and fineness requirements.
