Spodumene ore (Mohs 6.5–7.5) presents exceptional abrasiveness that accelerates roller wear in conventional mills by up to 300%. This hardness demands grinding technology specifically engineered for ultra-resistant materials. Our LM Vertical Grinding Mill rises to this challenge with robust engineering solutions designed to optimize lithium recovery while minimizing operational costs.
At the core of our LM Mill lies the Tungsten Carbide Overlay grinding rollers. Engineered to endure extreme abrasion, these rollers deliver up to 12,000 operating hours between maintenance intervals – quadrupling the industry average lifespan. This technology directly addresses spodumene’s destructive properties, significantly reducing downtime and replacement costs.
Consistent output fineness is critical for efficient lithium extraction. The LM Mill achieves a precise 74μm P80 particle size with a 92% passing rate, creating the ideal leach feed characteristics. This optimized particle size distribution increases acid reactivity during sulfuric acid leaching, enhancing lithium recovery rates by up to 15% compared to conventional grinding methods.
Our LM Vertical Mill series offers scalable configurations matching diverse production requirements. The LM190K (23-68 t/h), LM220K (36-105 t/h), and LM280K (50-170 t/h) models deliver the throughput needed for industrial-scale lithium processing. With a maximum feed size of 50mm and adjustable fineness between 170-45μm (80-325 mesh), operators maintain precise control over grinding circuits.
The LM Mill’s vertical design integrates grinding, drying, and classification in a single unit, reducing power consumption by up to 40% versus traditional grinding systems. Our high-torque main motors (ranging from 200kW to 1250kW) deliver exceptional efficiency, particularly when processing hard ores where energy costs typically dominate operational budgets.
LM Mills demonstrate exceptional compatibility with renewable energy sources. Solar-powered installations at major mining sites have achieved reductions of 8 tons of CO₂ per day during operation. The mill’s low-startup torque and variable speed operation facilitate seamless integration with intermittent power sources, supporting the industry’s decarbonization goals.
Unlike wet grinding circuits that consume significant water resources, the LM Mill operates as a dry grinding system. This eliminates water consumption in the comminution stage and prevents acid leach dilution downstream – a critical advantage for lithium operations located in water-stressed regions.
| Model | Grinding Plate (mm) | Capacity (t/h) | Output Fineness | Main Motor (kW) |
|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40μm | 500 |
| LM220K | 2200 | 36-105 | 170-45μm | 800 |
| LM280K | 2800 | 50-170 | 170-45μm | 1250 |
The LM Vertical Grinding Mill redefines operational efficiency in spodumene processing. By extending component lifespan through advanced wear protection and optimizing particle size for maximum lithium recovery, our technology significantly improves project economics. The mill’s energy-efficient design and compatibility with renewable power further reduce both operational costs and environmental impact – delivering a competitive edge in the rapidly expanding lithium market.
