Molino de barras industrial
The Heavy-Duty Rod Mill is engineered specifically for the pre-concentration grinding of tungsten-tin ores, gold, silver, and other precious metal ores before gravity separation.
Unlike ball mills, its steel rod grinding media delivers a linear contact grinding action, drastically reducing over-grinding and preserving particle size uniformity—critical for maximizing recovery rates in jigging, shaking table, and other gravity separation processes.
Built for continuous operation in harsh mining environments, it is a trusted solution for mineral processing plants in Russia and other region.
Core Technical Highlights
Low Over-Grinding Design for High Recovery
The linear contact of steel rods minimizes fine particle generation, preserving the liberation of coarse and medium-sized tungsten-tin and precious metal grains.
This directly boosts recovery rates in downstream gravity separation processes, preventing valuable minerals from being lost in tailings due to excessive grinding.
Uniform Particle Size Distribution
Advanced internal lifter geometry and optimized rod grading ensure consistent, even grinding. The resulting product has a narrow particle size distribution, eliminating over-sized particles that disrupt gravity separation and fine particles that lead to mineral loss.
Heavy-Duty & Wear-Resistant Construction
The mill shell is made of thick steel plate with high-manganese steel liners, offering exceptional resistance to abrasion from hard tungsten-tin and precious metal ores. The reinforced main bearing and girth gear drive system ensure stable operation under continuous, heavy loads in remote mining sites.
Customizable Discharge Options
Available in overflow type and peripheral discharge type configurations:
-- Peripheral discharge models deliver more uniform particle size, ideal for gravity separation processes.
-- Overflow models support continuous, high-capacity grinding for larger mining operations.
Energy-Efficient & Low Maintenance
A high-efficiency girth gear and pinion drive reduces power consumption, while modular liner design and standardized spare parts simplify maintenance.
The mill is built to operate reliably in extreme climates, from Russia’s cold regions to Uzbekistan's arid mining zones.
